Public Custom Event Invoked As TypedEventHandler(Of KeyboardAccelerator, KeyboardAcceleratorInvokedEventArgs) 

Examples

This example shows how to override the "Select all" command (Ctrl+A keyboard accelerator) in a custom ListView control. We also set the Handled property to true to stop the event bubbling further.

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;
    }
  }
  …
}

Remarks

Handle this event to override the default KeyboardAccelerator behavior.
