Public Event CausesValidationChanged As EventHandler

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the CausesValidationChanged 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 type ToolStrip named ToolStrip1. Then ensure that the event handler is associated with the CausesValidationChanged event.

Private Sub ToolStrip1_CausesValidationChanged(sender as Object, e as EventArgs) _ 
     Handles ToolStrip1.CausesValidationChanged

   MessageBox.Show("You are in the ToolStrip.CausesValidationChanged event.")

End Sub
