C#WPF實戰出真汁06--【系統設置】--餐桌類型設置

1、系統設置的基本概念

系統設置是用于配置和管理餐桌類型和菜品類型，是維護整個系統的基礎數據。通過系統設置，用戶可以調整餐桌類型的添加，刪除，編輯，分頁，查詢，重置，列表，選擇等。

2、布局設計?

餐桌類型設置及菜品類型設置是通過TabControl控件實現的。不過要注意的是，左側每個菜單點擊時，右側呈現出來的是用戶控件，是用戶控件，而不是窗體。

1、控件介紹

TabControl 是一種功能強大且靈活的控件，適用于需要分頁顯示內容的場景。通過合理使用其屬性和事件，可以創建出滿足各種需求的用戶界面。TabControl 是一種常見的用戶界面控件，用于在多個選項卡之間切換內容。它通常由一組標簽頁（TabPage）組成，每個標簽頁包含不同的內容，用戶可以通過點擊標簽頁頭來切換顯示的內容。在 WPF 中，TabControl 的使用方式更加靈活，通常與數據綁定結合使用。以下是 XAML 示例：

<TabControl><TabItem Header="選項卡1"><Label Content="這是第一個選項卡的內容"/></TabItem><TabItem Header="選項卡2"><Label Content="這是第二個選項卡的內容"/></TabItem>
</TabControl>

?TabControl 的事件，TabControl 提供了多個事件用于響應用戶操作，以下是常見事件：

SelectedIndexChanged：當選中標簽頁發生變化時觸發。該事件本項目中必須用到
Selecting：在選中標簽頁之前觸發，可以取消選中操作。
Selected：在選中標簽頁之后觸發。

2、布局應用

Panuon.UI.Silver控件庫中帶有分頁控件Pagination，這個分頁控件蠻好用，靈活方便好使，支持隨時修改每頁條數，自動更新分頁導航。

3、視圖模型

在WPF中，ViewModel是MVVM（Model-View-ViewModel）架構模式的核心組件，負責連接View（界面）和Model（數據/業務邏輯）。

ViewModel的核心作用
數據綁定橋梁：通過屬性暴露數據，供View雙向綁定，實現數據自動同步。
命令處理：封裝UI操作邏輯，通過ICommand接口實現事件響應（如按鈕點擊）。
狀態管理：維護View的視覺狀態（如加載中、錯誤提示等）。
