事件類型

範例

這個範例展示了如何在自訂 ListView 控制項中覆寫「全部選取」指令（Ctrl+A 鍵盤加速器）。 我們也將 Handled 屬性設為 ， true 以阻止事件繼續冒泡。

public class MyListView : ListView
{
  …
  protected override void OnKeyboardAcceleratorInvoked(KeyboardAcceleratorInvokedEventArgs args) 
  {
    if(args.KeyboardAccelerator.Key == VirtualKey.A 
      && args.KeyboardAccelerator.Modifiers == VirtualKeyModifiers.Control)
    {
      CustomSelectAll(TypeOfSelection.OnlyNumbers); 
      args.Handled = true;
    }
  }
  …
}

備註

處理此事件以覆蓋預設 的 KeyboardAccelerator 行為。
