CheckBox.AutoCheck 属性

获取或设置一个值，该值指示当单击某一 CheckBox 时，Checked 或 CheckState 的值以及该 CheckBox 的外观是否自动改变。

**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 AutoCheck As Boolean
用法
Dim instance As CheckBox
Dim value As Boolean

value = instance.AutoCheck

instance.AutoCheck = value

public bool AutoCheck { get; set; }

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

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

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

public function get AutoCheck () : boolean

public function set AutoCheck (value : boolean)

属性值

如果 Checked 值或 CheckState 值及该控件的外观在发生 Click 事件时自动更改，则为 true；否则为 false。默认值为 true。

备注

如果将 AutoCheck 设置为假，则需要添加代码以更新 Click 事件处理程序中的 Checked 或 CheckState 值。

示例

下面的代码示例创建了一个 CheckBox 并对它进行了初始化，为它赋予切换按钮的外观，将 AutoCheck 设置为 false，并将该复选框添加到 Form 中。

Public Sub InstantiateMyCheckBox()
    ' Create and initialize a CheckBox.   
    Dim checkBox1 As New CheckBox()
    
    ' Make the check box control appear as a toggle button.
    checkBox1.Appearance = Appearance.Button
    
    ' Turn off the update of the display on the click of the control.
    checkBox1.AutoCheck = False
    
    ' Add the check box control to the form.
    Controls.Add(checkBox1)
End Sub 'InstantiateMyCheckBox

public void InstantiateMyCheckBox()
 {
    // Create and initialize a CheckBox.   
    CheckBox checkBox1 = new CheckBox(); 
    
    // Make the check box control appear as a toggle button.
    checkBox1.Appearance = Appearance.Button;
 
    // Turn off the update of the display on the click of the control.
    checkBox1.AutoCheck = false;
 
    // Add the check box control to the form.
    Controls.Add(checkBox1);
 }
 

public:
   void InstantiateMyCheckBox()
   {
      // Create and initialize a CheckBox.   
      CheckBox^ checkBox1 = gcnew CheckBox;
      
      // Make the check box control appear as a toggle button.
      checkBox1->Appearance = Appearance::Button;
      
      // Turn off the update of the display on the click of the control.
      checkBox1->AutoCheck = false;
      
      // Add the check box control to the form.
      this->Controls->Add( checkBox1 );
   }

public void InstantiateMyCheckBox()
{
    // Create and initialize a CheckBox.   
    CheckBox checkBox1 = new CheckBox();

    // Make the check box control appear as a toggle button.
    checkBox1.set_Appearance(Appearance.Button);

    // Turn off the update of the display on the click of the control.
    checkBox1.set_AutoCheck(false);

    // Add the check box control to the form.
    get_Controls().Add(checkBox1);
} //InstantiateMyCheckBox

public function InstantiateMyCheckBox()
 {
    // Create and initialize a CheckBox.   
    var checkBox1 : CheckBox = new CheckBox(); 
    
    // Make the check box control appear as a toggle button.
    checkBox1.Appearance = Appearance.Button;
 
    // Turn off the update of the display on the click of the control.
    checkBox1.AutoCheck = false;
 
    // Add the check box control to the form.
    Controls.Add(checkBox1);
 }
