For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ContextMenuStripChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox..::.Show with Console..::.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. Then name the instance Control1 and ensure that the event handler is associated with the ContextMenuStripChanged event.

Private Sub Control1_ContextMenuStripChanged(sender as Object, e as EventArgs) _ 
     Handles Control1.ContextMenuStripChanged

   MessageBox.Show("You are in the Control.ContextMenuStripChanged event.")

End Sub

private void Control1_ContextMenuStripChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.ContextMenuStripChanged event.");

}
