Control.TabIndex 屬性

定義

取得或設定控制項容器中的控制項定位順序。Gets or sets the tab order of the control within its container.

public:
 property int TabIndex { int get(); void set(int value); };
public int TabIndex { get; set; }
member this.TabIndex : int with get, set
Public Property TabIndex As Integer

屬性值

在控制項集合內的控制項之索引值 (在其容器內)。The index value of the control within the set of controls within its container. 容器內的控制項會包含在定位順序中。The controls in the container are included in the tab order.

範例

下列程式碼範例會將 Button 新增至表單,並設定其一些通用屬性。The following code example adds a Button to a form and sets some of its common properties. 這個範例會將按鈕錨定表單右下角,讓它在調整大小表單時保持相對位置。The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. 接下來,它會設定 BackgroundImage,並將按鈕大小調整為與 Image 相同的大小。Next it sets the BackgroundImage and resizes the button to the same size as the Image. 然後,此範例會將 TabStop 設定為 true,並設定 TabIndex 屬性。The example then sets the TabStop to true and sets the TabIndex property. 最後,它會加入事件處理常式來處理按鈕的 Click 事件。Lastly, it adds an event handler to handle the Click event of the button. 這個範例需要您的 ImageList,名為 imageList1This example requires that you have an ImageList named imageList1.

   // Add a button to a form and set some of its common properties.
private:
   void AddMyButton()
   {
      // Create a button and add it to the form.
      Button^ button1 = gcnew Button;

      // Anchor the button to the bottom right corner of the form
      button1->Anchor = static_cast<AnchorStyles>(AnchorStyles::Bottom | AnchorStyles::Right);

      // Assign a background image.
      button1->BackgroundImage = imageList1->Images[ 0 ];

      // Specify the layout style of the background image. Tile is the default.
      button1->BackgroundImageLayout = ImageLayout::Center;

      // Make the button the same size as the image.
      button1->Size = button1->BackgroundImage->Size;

      // Set the button's TabIndex and TabStop properties.
      button1->TabIndex = 1;
      button1->TabStop = true;

      // Add a delegate to handle the Click event.
      button1->Click += gcnew System::EventHandler( this, &Form1::button1_Click );

      // Add the button to the form.
      this->Controls->Add( button1 );
   }
// Add a button to a form and set some of its common properties.
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;
   
   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form.
   this.Controls.Add(button1);
}
' Add a button to a form and set some of its common properties.
Private Sub AddMyButton()
   ' Create a button and add it to the form.
   Dim button1 As New Button()
   
   ' Anchor the button to the bottom right corner of the form
   button1.Anchor = AnchorStyles.Bottom Or AnchorStyles.Right
   
   ' Assign a background image.
   button1.BackgroundImage = imageList1.Images(0)

   ' Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center

   button1.Size = button1.BackgroundImage.Size
   
   ' Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1
   button1.TabStop = True

   ' Add a delegate to handle the Click event.
   AddHandler button1.Click, AddressOf Me.button1_Click
   
   ' Add the button to the form.
   Me.Controls.Add(button1)
End Sub

備註

Tab 鍵索引可以包含大於或等於零的任何有效整數,也就是定位順序中較低的數位。A tab index can consist of any valid integer greater than or equal to zero, lower numbers being earlier in the tab order. 如果相同父控制項上有一個以上的控制項具有相同的索引標籤索引,控制項的迭置順序會決定要迴圈流覽控制項的順序。If more than one control on the same parent control has the same tab index, the z-order of the controls determines the order to cycle through the controls.

若要讓控制項包含在定位順序中,其 TabStop 屬性必須設定為 trueFor a control to be included in the tab order, its TabStop property must be set to true.
