Control.TabStop 属性

获取或设置一个值，该值指示用户能否使用 Tab 键将焦点放到该控件上。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property TabStop As Boolean
用法
Dim instance As Control
Dim value As Boolean

value = instance.TabStop

instance.TabStop = value

public bool TabStop { get; set; }

public:
property bool TabStop {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_TabStop ()

/** @property */
public void set_TabStop (boolean value)

public function get TabStop () : boolean

public function set TabStop (value : boolean)

属性值

如果用户可以用 Tab 键将焦点放到此控件上，则为 true；反之，则为 false。默认为 true。

提示

对于 Form 类的实例，该属性将始终返回 true。

备注

当用户按下 Tab 键时，输入焦点设置为 Tab 键顺序中的下一个控件。TabStop 属性值为 false 的控件不包括在按 Tab 键顺序排列的控件集合中。Tab 键顺序可以通过设置控件的 TabIndex 属性值来操作。

示例

下面的代码示例将 Button 添加到窗体并设置该控件的一些通用属性。示例将该按钮定位在窗体的右下角，因此调整窗体大小时其相对位置不变。接着，它设置 BackgroundImage 并将该按钮的大小调整为与 Image 同样的大小。然后，该示例将 TabStop 设置为 true，并设置 TabIndex 属性。最后，它添加一个事件处理程序以处理按钮的 Click 事件。此示例要求您有一个名为 imageList1 的 ImageList。

' 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()

   button1.Anchor = AnchorStyles.Bottom Or AnchorStyles.Right
   
   ' Assign a background image.
