Tabcontrol動態添加TabPage(獲取或設置當前選項卡及其屬性)

http://blog.csdn.net/xiongxyt2/article/details/6920575

?MultiLine 屬性用true 或false來確定是否可以多行顯示?
?Appearance 屬性設置選項卡的顯示方式，Normal,Buttons和FlatButtons為三種不同的顯示方式。
?
?TabPages屬性設置選項卡的一系列屬性，包括字體，圖片和背景等
? Enabled 屬性設置為 true 或 false 表示啟用或禁用選項

新建一個WinForm程序，拖一個TabControl（在tabPages屬性里面將默認的兩個TabPage刪除）和三個Button（增加、刪除、修改）

public?partial?class?Form1?:?Form??
????{??
????????private?int?index?=?0;??
????????public?Form1()??
????????{??
????????????InitializeComponent();??
????????}??
??
????????private?void?Form1_Load(object?sender,?EventArgs?e)??
????????{??
????????????//this.tabControl1.SelectedIndex?=?1;??
????????}??
??
????????private?void?btnAdd_Click(object?sender,?EventArgs?e)??
????????{??
????????????TabPage?Page?=?new?TabPage();??
????????????Page.Name?=?"Page"?+?index.ToString();??
????????????Page.Text?=?"tabPage"?+?index.ToString();??
????????????Page.TabIndex?=?index;??
????????????this.tabControl1.Controls.Add(Page);??
?
????????????#region?三種設置某個選項卡為當前選項卡的方法??
????????????//this.tabControl1.SelectedIndex?=?index;??
????????????this.tabControl1.SelectedTab?=?Page;??
????????????//this.tabControl1.SelectTab("Page"?+?index.ToString());??
????????????#endregion???
??
????????????index++;??
????????}??
??
????????private?void?btnRemove_Click(object?sender,?EventArgs?e)??
????????{??
????????????bool?first?=?true;??
????????????if?(index?>?0)??
????????????{??
????????????????#region?兩種刪除某個選項卡的方法??
????????????????this.tabControl1.Controls.RemoveAt(this.tabControl1.SelectedIndex);??
????????????????//this.tabControl1.Controls.Remove(this.tabControl1.TabPages[this.tabControl1.TabPages.Count-1]);??
????????????????#endregion???
????????????}??
????????????else??
????????????{??
????????????????return;??
????????????}??
?
????????????#region?用于設置刪除最后一個TabPage后，將倒數第二個設置為當前選項卡??
????????????if?(first)??
????????????{??
????????????????this.tabControl1.SelectedIndex?=?--index?-?1;??
????????????????first?=?false;??
????????????}??
????????????else??
????????????{??
????????????????this.tabControl1.SelectedIndex?=?index--;??
????????????}??
????????????#endregion???
????????}??
??
????????private?void?btnUpdate_Click(object?sender,?EventArgs?e)??
????????{??
????????????this.tabControl1.SelectedTab.Text?=?"xyt";//修改當前選項卡的屬性??
????????????//this.tabControl1.SelectedTab.Name?=?"";??
????????????//this.tabControl1.SelectedTab.Tag?=?"";??
????????????//this.tabControl1.SelectedTab.Select();??
????????}??
????}??

上面同好幾種方法來設置當前選項卡，用tabControl1.SelectedTab更方便，因為他返回的是TabPage對象，可以通過這個對象對當前TabPage進行你想要的操作
