IButtonControl.PerformClick IButtonControl.PerformClick IButtonControl.PerformClick IButtonControl.PerformClick Method

定義

コントロールの Click イベントを生成します。Generates a Click event for the control.

public:
 void PerformClick();
public void PerformClick ();
abstract member PerformClick : unit -> unit
Public Sub PerformClick ()

次の例では、 ButtonBaseクラスを継承しIButtonControl 、インターフェイスを実装しています。The following example inherits from the ButtonBase class and implements the IButtonControl interface. 実装は、 DialogResultプロパティ、メソッド、 NotifyDefaultおよびPerformClickメソッドに追加されます。Implementation is added to the DialogResult property and the NotifyDefault and PerformClick methods.

注釈

このメソッドは、フォーカスのあるボタン、またはユーザーが ENTER キーを押したときに既定のボタン (他のボタンがフォーカスされていない場合) に対して呼び出されます。This method is called for the button that has focus, or for the default button (if no other button has focus) when the user presses the ENTER key. このメソッドは、ボタンが [キャンセル] ボタンとして設定されている場合にユーザーが ESC キーを押したときにも呼び出されます。This method is also called when the user presses the ESC key if the button is set as the cancel button.
