【轉】WPF自定義控件與樣式(3)-TextBox RichTextBox PasswordBox樣式、水印、Label標簽、功能擴展...

一．前言.預覽

　　申明：WPF自定義控件與樣式是一個系列文章，前后是有些關聯的，但大多是按照由簡到繁的順序逐步發布的等。

本文主要是對文本輸入控件進行樣式開發，及相關擴展功能開發，主要內容包括：

  • 基本文本框TextBox控件樣式及擴展功能，實現了樣式、水印、Label標簽、功能擴展；
  • 富文本框RichTextBox控件樣式；
  • 密碼輸入框PasswordBox控件樣式及擴展功能；

二．基本文本框TextBox控件樣式及擴展功能

2.1 TextBox基本樣式

樣式代碼如下：??

<!--TextBox默認樣式--><Style TargetType="{x:Type TextBox}" x:Key="DefaultTextBox"><Setter Property="ContextMenu" Value="{DynamicResource TextBoxContextMenu}" /><Setter Property="SelectionBrush" Value="{StaticResource TextSelectionBrush}" /><Setter Property="FontFamily" Value="{StaticResource FontFamily}" /><Setter Property="FontSize" Value="{StaticResource FontSize}" /><Setter Property="BorderThickness" Value="1" /><Setter Property="MinHeight" Value="26" /><Setter Property="Width" Value="100" /><Setter Property="Background" Value="{StaticResource TextBackground}" /><Setter Property="Foreground" Value="{StaticResource TextForeground}" /><Setter Property="Padding" Value="0" /><Setter Property="BorderBrush" Value="{StaticResource ControlBorderBrush}" /><Setter Property="local:ControlAttachProperty.FocusBorderBrush" Value="{StaticResource FocusBorderBrush}" /><Setter Property="local:ControlAttachProperty.MouseOverBorderBrush" Value="{StaticResource MouseOverBorderBrush}" /><Setter Property="VerticalContentAlignment" Value="Center" /><!-- change SnapsToDevicePixels to True to view a better border and validation error --><Setter Property="SnapsToDevicePixels" Value="True" /><!--英 ['k?r?t]  美 ['k?r?t]  插入符號--><Setter Property="CaretBrush" Value="{StaticResource TextForeground}" /><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type TextBox}"><Grid x:Name="PART_Root"><Border x:Name="Bg" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"CornerRadius="{TemplateBinding local:ControlAttachProperty.CornerRadius}"BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" /><Grid x:Name="PART_InnerGrid"><Grid.ColumnDefinitions><ColumnDefinition  Width="Auto" /><ColumnDefinition Width="*" /><ColumnDefinition  Width="Auto" /></Grid.ColumnDefinitions><!--Label區域--><ContentControl x:Name="Label" Margin="1" Template="{TemplateBinding local:ControlAttachProperty.LabelTemplate}"Content="{TemplateBinding local:ControlAttachProperty.Label}"/><!--內容區域--><ScrollViewer x:Name="PART_ContentHost" BorderThickness="0" Grid.Column="1" IsTabStop="False" Margin="2"VerticalAlignment="Stretch" Background="{x:Null}" /><!--水印--><TextBlock x:Name="Message"  Padding="{TemplateBinding Padding}" Visibility="Collapsed"Text="{TemplateBinding local:ControlAttachProperty.Watermark}" Grid.Column="1"Foreground="{TemplateBinding Foreground}" IsHitTestVisible="False" Opacity="{StaticResource WatermarkOpacity}"HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="5,2,5,2" /><!--附加內容區域--><Border x:Name="PART_AttachContent" Grid.Column="2" Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" ><ContentControl VerticalAlignment="Center" VerticalContentAlignment="Center" Template="{TemplateBinding local:ControlAttachProperty.AttachContent}" /></Border></Grid></Grid><ControlTemplate.Triggers><!--顯示水印--><DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=Text}" Value=""><Setter TargetName="Message" Property="Visibility" Value="Visible" /></DataTrigger><Trigger Property="IsMouseOver" Value="True"><Setter Property="BorderBrush" Value="{Binding Path=(local:ControlAttachProperty.MouseOverBorderBrush),RelativeSource={RelativeSource Self}}"/></Trigger><Trigger Property="IsFocused" Value="True"><Setter  Property="BorderBrush" Value="{Binding Path=(local:ControlAttachProperty.FocusBorderBrush),RelativeSource={RelativeSource Self}}"/></Trigger><!--不可用--><Trigger Property="IsEnabled" Value="False"><Setter TargetName="PART_Root" Property="Opacity" Value="{StaticResource DisableOpacity}" /></Trigger><!--只讀時，禁用PART_AttachContent--><Trigger Property="IsReadOnly" Value="True"><Setter TargetName="PART_AttachContent" Property="IsEnabled" Value="False" /><Setter TargetName="Bg" Property="Opacity" Value="{StaticResource ReadonlyOpacity}" /><Setter TargetName="PART_ContentHost" Property="Opacity" Value="{StaticResource ReadonlyOpacity}" /><Setter TargetName="Label" Property="Opacity" Value="{StaticResource ReadonlyOpacity}" /></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style>

模板內容主要包含四部分：

  • 用于實現Label標簽的預留區域；
  • TextBox本身的文本輸入顯示部分；
  • 水印顯示部分；
  • 功能擴展的預留區域；

　　其中Label標簽、功能擴展，還有輸入框的不同狀態顯示效果都是通過附加屬性來實現的，其實從本質上附加屬性和控件上定義的依賴屬性是同一個概念，有些時候附加屬性會更加方便，對于一些可共用的屬性，就比較方便，這一點怎本文是有體現的。上面代碼使用到的附加屬性代碼：

#region FocusBorderBrush 焦點邊框色，輸入控件public static readonly DependencyProperty FocusBorderBrushProperty = DependencyProperty.RegisterAttached("FocusBorderBrush", typeof(Brush), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null));public static void SetFocusBorderBrush(DependencyObject element, Brush value){element.SetValue(FocusBorderBrushProperty, value);}public static Brush GetFocusBorderBrush(DependencyObject element){return (Brush)element.GetValue(FocusBorderBrushProperty);}#endregion#region MouseOverBorderBrush 鼠標進入邊框色，輸入控件public static readonly DependencyProperty MouseOverBorderBrushProperty =DependencyProperty.RegisterAttached("MouseOverBorderBrush", typeof(Brush), typeof(ControlAttachProperty),new FrameworkPropertyMetadata(Brushes.Transparent,FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.Inherits));/// <summary>/// Sets the brush used to draw the mouse over brush./// </summary>public static void SetMouseOverBorderBrush(DependencyObject obj, Brush value){obj.SetValue(MouseOverBorderBrushProperty, value);}/// <summary>/// Gets the brush used to draw the mouse over brush./// </summary>[AttachedPropertyBrowsableForType(typeof(TextBox))][AttachedPropertyBrowsableForType(typeof(CheckBox))][AttachedPropertyBrowsableForType(typeof(RadioButton))][AttachedPropertyBrowsableForType(typeof(DatePicker))][AttachedPropertyBrowsableForType(typeof(ComboBox))][AttachedPropertyBrowsableForType(typeof(RichTextBox))]public static Brush GetMouseOverBorderBrush(DependencyObject obj){return (Brush)obj.GetValue(MouseOverBorderBrushProperty);}#endregion#region AttachContentProperty 附加組件模板/// <summary>/// 附加組件模板/// </summary>public static readonly DependencyProperty AttachContentProperty = DependencyProperty.RegisterAttached("AttachContent", typeof(ControlTemplate), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null));public static ControlTemplate GetAttachContent(DependencyObject d){return (ControlTemplate)d.GetValue(AttachContentProperty);}public static void SetAttachContent(DependencyObject obj, ControlTemplate value){obj.SetValue(AttachContentProperty, value);}#endregion#region WatermarkProperty 水印/// <summary>/// 水印/// </summary>public static readonly DependencyProperty WatermarkProperty = DependencyProperty.RegisterAttached("Watermark", typeof(string), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(""));public static string GetWatermark(DependencyObject d){return (string)d.GetValue(WatermarkProperty);}public static void SetWatermark(DependencyObject obj, string value){obj.SetValue(WatermarkProperty, value);}#endregion#region CornerRadiusProperty Border圓角/// <summary>/// Border圓角/// </summary>public static readonly DependencyProperty CornerRadiusProperty = DependencyProperty.RegisterAttached("CornerRadius", typeof(CornerRadius), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null));public static CornerRadius GetCornerRadius(DependencyObject d){return (CornerRadius)d.GetValue(CornerRadiusProperty);}public static void SetCornerRadius(DependencyObject obj, CornerRadius value){obj.SetValue(CornerRadiusProperty, value);}#endregion#region LabelProperty TextBox的頭部Label/// <summary>/// TextBox的頭部Label/// </summary>public static readonly DependencyProperty LabelProperty = DependencyProperty.RegisterAttached("Label", typeof(string), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static string GetLabel(DependencyObject d){return (string)d.GetValue(LabelProperty);}public static void SetLabel(DependencyObject obj, string value){obj.SetValue(LabelProperty, value);}#endregion#region LabelTemplateProperty TextBox的頭部Label模板/// <summary>/// TextBox的頭部Label模板/// </summary>public static readonly DependencyProperty LabelTemplateProperty = DependencyProperty.RegisterAttached("LabelTemplate", typeof(ControlTemplate), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static ControlTemplate GetLabelTemplate(DependencyObject d){return (ControlTemplate)d.GetValue(LabelTemplateProperty);}public static void SetLabelTemplate(DependencyObject obj, ControlTemplate value){obj.SetValue(LabelTemplateProperty, value);}#endregion

2.2 水印效果實現

　　通過2.1的代碼示例，可以看出，水印是內置了一個TextBlock，用附加屬性ControlAttachProperty.Watermark設置水印內容，在觸發器中檢測，當TextBox中有輸入值，則隱藏水印的TextBlock，使用示例：??

<StackPanel><TextBox Width="140" Height="40" Margin="3" TextWrapping="Wrap" VerticalScrollBarVisibility="Visible">333333333333333</TextBox><TextBox Width="150" Height="30" Margin="3" core:ControlAttachProperty.Watermark="我是水印" core:ControlAttachProperty.CornerRadius="2"></TextBox><TextBox Width="150" Height="30" Margin="3" IsReadOnly="True" core:ControlAttachProperty.CornerRadius="15" SnapsToDevicePixels="True" >我是只讀的</TextBox><TextBox Width="150" Height="30" Margin="3" IsEnabled="False">IsEnabled="False"</TextBox><TextBox Width="150" Height="30" core:ControlAttachProperty.Watermark="我是水印"></TextBox></StackPanel>

　效果：

　　

2.3 Label標簽實現

　　參考2.1的代碼，預留了Label的區域，通過設置附加屬性local:ControlAttachProperty.Label設置標簽文本，local:ControlAttachProperty.LabelTemplate設置Label標簽的模板樣式，即可自定義實現Label標簽，自定義樣式：

<!--TextBox包含附加屬性Label的樣式--><Style TargetType="{x:Type TextBox}" x:Key="LabelTextBox" BasedOn="{StaticResource DefaultTextBox}"><Setter Property="local:ControlAttachProperty.LabelTemplate" ><Setter.Value><ControlTemplate TargetType="ContentControl"><Border Width="60" Background="{StaticResource TextLabelBackground}"><TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="3" Text="{TemplateBinding Content}"></TextBlock></Border></ControlTemplate></Setter.Value></Setter></Style>

使用示例及效果：?

<TextBox Width="200" Height="30" Margin="3" core:ControlAttachProperty.Watermark="請輸入姓名" Style="{StaticResource LabelTextBox}" core:ControlAttachProperty.Label="姓名："></TextBox>

2.4 擴展功能及自定義擴展

　　思路和2.3的Label標簽實現相似，清除文本框內的內容是一個常用需求，我們就線擴展一個這么一個功能的TextBox，通過附加屬性ControlAttachProperty.AttachContent定義擴展功能的模板，模板內定義的是一個按鈕FButton（可參考上一篇，本文末尾附錄中有鏈接）??

<!--TextBox包含清除Text按鈕的樣式--><Style TargetType="{x:Type TextBox}" x:Key="ClearButtonTextBox" BasedOn="{StaticResource DefaultTextBox}"><Setter Property="local:ControlAttachProperty.AttachContent"><Setter.Value><ControlTemplate><local:FButton FIcon="&#xe60a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"local:ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.ClearTextCommand" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"Margin="1,3,1,4" FIconSize="14" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></ControlTemplate></Setter.Value></Setter></Style>

這里定義的是顯示效果，清除TextBox內容的邏輯代碼如何實現的呢？還是附加屬性：

  • ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" ：注入事件到當前Button
  • Command="local:ControlAttachProperty.ClearTextCommand"：定義Fbutton的命令對象實例Command
  • CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"：把TextBox作為參數傳入

　　邏輯代碼如下，從代碼不難看出，它是支持多種輸入控件的內容清除的，也就是說該擴展功能可以輕松支持其他輸入控件，第四節密碼數據的清除也是這樣使用的。

#region IsClearTextButtonBehaviorEnabledProperty 清除輸入框Text值按鈕行為開關（設為ture時才會綁定事件）/// <summary>/// 清除輸入框Text值按鈕行為開關/// </summary>public static readonly DependencyProperty IsClearTextButtonBehaviorEnabledProperty = DependencyProperty.RegisterAttached("IsClearTextButtonBehaviorEnabled", typeof(bool), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(false, IsClearTextButtonBehaviorEnabledChanged));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static bool GetIsClearTextButtonBehaviorEnabled(DependencyObject d){return (bool)d.GetValue(IsClearTextButtonBehaviorEnabledProperty);}public static void SetIsClearTextButtonBehaviorEnabled(DependencyObject obj, bool value){obj.SetValue(IsClearTextButtonBehaviorEnabledProperty, value);}/// <summary>/// 綁定清除Text操作的按鈕事件/// </summary>private static void IsClearTextButtonBehaviorEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e){var button = d as FButton;if (e.OldValue != e.NewValue && button != null){button.CommandBindings.Add(ClearTextCommandBinding);}}#endregion#region ClearTextCommand 清除輸入框Text事件命令/// <summary>/// 清除輸入框Text事件命令，需要使用IsClearTextButtonBehaviorEnabledChanged綁定命令/// </summary>public static RoutedUICommand ClearTextCommand { get; private set; }/// <summary>/// ClearTextCommand綁定事件/// </summary>private static readonly CommandBinding ClearTextCommandBinding;/// <summary>/// 清除輸入框文本值/// </summary>private static void ClearButtonClick(object sender, ExecutedRoutedEventArgs e){var tbox = e.Parameter as FrameworkElement;if (tbox == null) return;if (tbox is TextBox){((TextBox)tbox).Clear();}if (tbox is PasswordBox){((PasswordBox)tbox).Clear();}if (tbox is ComboBox){var cb = tbox as ComboBox;cb.SelectedItem = null;cb.Text = string.Empty;}if (tbox is MultiComboBox){var cb = tbox as MultiComboBox;cb.SelectedItem = null;cb.UnselectAll();cb.Text = string.Empty;}if (tbox is DatePicker){var dp = tbox as DatePicker;dp.SelectedDate = null;dp.Text = string.Empty;}tbox.Focus();}#endregion/// <summary>/// 靜態構造函數/// </summary>static ControlAttachProperty(){//ClearTextCommandClearTextCommand = new RoutedUICommand();ClearTextCommandBinding = new CommandBinding(ClearTextCommand);ClearTextCommandBinding.Executed += ClearButtonClick;//OpenFileCommandOpenFileCommand = new RoutedUICommand();OpenFileCommandBinding = new CommandBinding(OpenFileCommand);OpenFileCommandBinding.Executed += OpenFileButtonClick;//OpenFolderCommandOpenFolderCommand = new RoutedUICommand();OpenFolderCommandBinding = new CommandBinding(OpenFolderCommand);OpenFolderCommandBinding.Executed += OpenFolderButtonClick;SaveFileCommand = new RoutedUICommand();SaveFileCommandBinding = new CommandBinding(SaveFileCommand);SaveFileCommandBinding.Executed += SaveFileButtonClick;}

效果：

　　

當然我們也可以自定義擴展其他功能，如：??

<TextBox Width="200" Height="30" Margin="3" core:ControlAttachProperty.Watermark="查詢關鍵詞" IsEnabled="True"><core:ControlAttachProperty.AttachContent><ControlTemplate><StackPanel Orientation="Horizontal"><core:FButton FIcon="&#xe60b;"  Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"FIconSize="18" Margin="1,1,2,3" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/><core:FButton FIcon="&#xe628;"  Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"FIconSize="22" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></StackPanel></ControlTemplate></core:ControlAttachProperty.AttachContent></TextBox>

效果：

由上不難同時實現Label標簽和清除文本內容的樣式：

<!--TextBox包含附加屬性Label，以及ClearText按鈕的樣式--><Style TargetType="{x:Type TextBox}" x:Key="LabelClearButtonTextBox" BasedOn="{StaticResource DefaultTextBox}"><Setter Property="local:ControlAttachProperty.LabelTemplate" ><Setter.Value><ControlTemplate TargetType="ContentControl"><Border Width="60" Background="{StaticResource TextLabelBackground}"><TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="3" Text="{TemplateBinding Content}"></TextBlock></Border></ControlTemplate></Setter.Value></Setter><Setter Property="local:ControlAttachProperty.AttachContent"><Setter.Value><ControlTemplate><local:FButton FIcon="&#xe60a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"local:ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.ClearTextCommand" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"Margin="0,3,1,4" FIconSize="14" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></ControlTemplate></Setter.Value></Setter></Style>

2.6 文件選擇輸入相關擴展

　　先看看效果，就明白了。

　　?

具體實現原理和上面2.4差不多 ，實現了三個文件、文件夾選擇相關的功能擴展，樣式代碼：

<!--LabelOpenFileTextBox--><Style TargetType="{x:Type TextBox}" x:Key="LabelOpenFileTextBox" BasedOn="{StaticResource LabelClearButtonTextBox}"><Setter Property="local:ControlAttachProperty.Label" Value="文件路徑"/><Setter Property="local:ControlAttachProperty.Watermark" Value="選擇文件路徑"/><Setter Property="local:ControlAttachProperty.AttachContent"><Setter.Value><ControlTemplate><local:FButton FIcon="&#xe64e;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"local:ControlAttachProperty.IsOpenFileButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.OpenFileCommand" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"Margin="0,1,0,1"  FIconSize="22" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></ControlTemplate></Setter.Value></Setter></Style><!--LabelOpenFolderTextBox--><Style TargetType="{x:Type TextBox}" x:Key="LabelOpenFolderTextBox" BasedOn="{StaticResource LabelClearButtonTextBox}"><Setter Property="local:ControlAttachProperty.Label" Value="設置路徑"/><Setter Property="local:ControlAttachProperty.Watermark" Value="選擇文件夾路徑"/><Setter Property="local:ControlAttachProperty.AttachContent"><Setter.Value><ControlTemplate><local:FButton FIcon="&#xe636;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"local:ControlAttachProperty.IsOpenFolderButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.OpenFolderCommand" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"Margin="0,1,0,1"  FIconSize="22" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></ControlTemplate></Setter.Value></Setter></Style><!--LabelSaveFileTextBox--><Style TargetType="{x:Type TextBox}" x:Key="LabelSaveFileTextBox" BasedOn="{StaticResource LabelClearButtonTextBox}"><Setter Property="local:ControlAttachProperty.Label" Value="保存路徑"/><Setter Property="local:ControlAttachProperty.Watermark" Value="選擇文件保存路徑"/><Setter Property="local:ControlAttachProperty.AttachContent"><Setter.Value><ControlTemplate><local:FButton FIcon="&#xe61a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"local:ControlAttachProperty.IsSaveFileButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.SaveFileCommand" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"Margin="0,1,0,1"  FIconSize="20" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/></ControlTemplate></Setter.Value></Setter></Style>

當然實現原理和2.4一樣，都是依賴屬性來實現事件的注入和綁定的，所以就不多廢話了：

#region IsOpenFileButtonBehaviorEnabledProperty 選擇文件命令行為開關/// <summary>/// 選擇文件命令行為開關/// </summary>public static readonly DependencyProperty IsOpenFileButtonBehaviorEnabledProperty = DependencyProperty.RegisterAttached("IsOpenFileButtonBehaviorEnabled", typeof(bool), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(false, IsOpenFileButtonBehaviorEnabledChanged));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static bool GetIsOpenFileButtonBehaviorEnabled(DependencyObject d){return (bool)d.GetValue(IsOpenFileButtonBehaviorEnabledProperty);}public static void SetIsOpenFileButtonBehaviorEnabled(DependencyObject obj, bool value){obj.SetValue(IsOpenFileButtonBehaviorEnabledProperty, value);}private static void IsOpenFileButtonBehaviorEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e){var button = d as FButton;if (e.OldValue != e.NewValue && button != null){button.CommandBindings.Add(OpenFileCommandBinding);}}#endregion#region IsOpenFolderButtonBehaviorEnabledProperty 選擇文件夾命令行為開關/// <summary>/// 選擇文件夾命令行為開關/// </summary>public static readonly DependencyProperty IsOpenFolderButtonBehaviorEnabledProperty = DependencyProperty.RegisterAttached("IsOpenFolderButtonBehaviorEnabled", typeof(bool), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(false, IsOpenFolderButtonBehaviorEnabledChanged));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static bool GetIsOpenFolderButtonBehaviorEnabled(DependencyObject d){return (bool)d.GetValue(IsOpenFolderButtonBehaviorEnabledProperty);}public static void SetIsOpenFolderButtonBehaviorEnabled(DependencyObject obj, bool value){obj.SetValue(IsOpenFolderButtonBehaviorEnabledProperty, value);}private static void IsOpenFolderButtonBehaviorEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e){var button = d as FButton;if (e.OldValue != e.NewValue && button != null){button.CommandBindings.Add(OpenFolderCommandBinding);}}#endregion#region IsSaveFileButtonBehaviorEnabledProperty 選擇文件保存路徑及名稱/// <summary>/// 選擇文件保存路徑及名稱/// </summary>public static readonly DependencyProperty IsSaveFileButtonBehaviorEnabledProperty = DependencyProperty.RegisterAttached("IsSaveFileButtonBehaviorEnabled", typeof(bool), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(false, IsSaveFileButtonBehaviorEnabledChanged));[AttachedPropertyBrowsableForType(typeof(TextBox))]public static bool GetIsSaveFileButtonBehaviorEnabled(DependencyObject d){return (bool)d.GetValue(IsSaveFileButtonBehaviorEnabledProperty);}public static void SetIsSaveFileButtonBehaviorEnabled(DependencyObject obj, bool value){obj.SetValue(IsSaveFileButtonBehaviorEnabledProperty, value);}private static void IsSaveFileButtonBehaviorEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e){var button = d as FButton;if (e.OldValue != e.NewValue && button != null){button.CommandBindings.Add(SaveFileCommandBinding);}}#endregion#region OpenFileCommand 選擇文件命令/// <summary>/// 選擇文件命令，需要使用IsClearTextButtonBehaviorEnabledChanged綁定命令/// </summary>public static RoutedUICommand OpenFileCommand { get; private set; }/// <summary>/// OpenFileCommand綁定事件/// </summary>private static readonly CommandBinding OpenFileCommandBinding;/// <summary>/// 執行OpenFileCommand/// </summary>private static void OpenFileButtonClick(object sender, ExecutedRoutedEventArgs e){var tbox = e.Parameter as FrameworkElement;var txt = tbox as TextBox;string filter = txt.Tag == null ?

?三．富文本框RichTextBox控件樣式

　　RichTextBox的樣式比較簡單：??

<!--***************************DefaultRichTextBox***************************--><Style x:Key="DefaultRichTextBox" TargetType="{x:Type RichTextBox}"><Setter Property="ContextMenu" Value="{DynamicResource TextBoxContextMenu}" /><Setter Property="SelectionBrush" Value="{StaticResource TextSelectionBrush}" /><Setter Property="FontFamily" Value="{StaticResource FontFamily}" /><Setter Property="FontSize" Value="{StaticResource FontSize}" /><Setter Property="BorderThickness" Value="1" /><Setter Property="BorderBrush" Value="{StaticResource ControlBorderBrush}" /><Setter Property="MinHeight" Value="26" /><Setter Property="MinWidth" Value="10" /><Setter Property="Background" Value="{StaticResource TextBackground}" /><Setter Property="Foreground" Value="{StaticResource TextForeground}" /><Setter Property="CaretBrush" Value="{StaticResource TextForeground}" /><Setter Property="local:ControlAttachProperty.FocusBorderBrush" Value="{StaticResource FocusBorderBrush}" /><Setter Property="local:ControlAttachProperty.MouseOverBorderBrush" Value="{StaticResource MouseOverBorderBrush}" /><Setter Property="Padding" Value="1" /><Setter Property="AllowDrop" Value="True" /><Setter Property="VerticalScrollBarVisibility" Value="Auto" /><Setter Property="FocusVisualStyle" Value="{x:Null}" /><Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst" /><!--該值指示是否啟用了筆勢--><Setter Property="Stylus.IsFlicksEnabled" Value="False" /><!--SnapsToDevicePixels:該值來確定呈現此元素是否應使用特定于設備的像素設置--><Setter Property="SnapsToDevicePixels" Value="True" /><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type TextBoxBase}"><Grid><Border x:Name="Bd"BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"Background="{TemplateBinding Background}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"><ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" /></Border></Grid><ControlTemplate.Triggers><Trigger Property="IsMouseOver" Value="True"><Setter Property="BorderBrush" Value="{Binding Path=(local:ControlAttachProperty.MouseOverBorderBrush),RelativeSource={RelativeSource Self}}"/></Trigger><Trigger Property="IsFocused" Value="True"><Setter  Property="BorderBrush" Value="{Binding Path=(local:ControlAttachProperty.FocusBorderBrush),RelativeSource={RelativeSource Self}}"/></Trigger><Trigger Property="IsEnabled" Value="False"><Setter TargetName="Bd" Property="Opacity" Value="0.5" /></Trigger><Trigger Property="IsReadOnly" Value="True"><Setter TargetName="Bd" Property="Opacity" Value="0.85" /></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style>

使用實力及效果：??

四．密碼輸入框PasswordBox控件樣式及擴展功能

　　密碼輸入控件的樣式和第二節文本框TextBox基本一致，就不做詳細的說明了，直接上樣式的代碼，相關邏輯（C#） 代碼和上面是一樣的（復用）。

<!--TextBox默認樣式--><Style TargetType="{x:Type PasswordBox}" x:Key="DefaultPasswordBox"><Setter Property="ContextMenu" Value="{DynamicResource TextBoxContextMenu}" /><Setter Property="SelectionBrush"
