Assembly: System.Windows.Forms (in system.windows.forms.dll)
/** @event */ public void add_CausesValidationChanged (EventHandler value) /** @event */ public void remove_CausesValidationChanged (EventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
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 System.Windows.Forms.MessageBox.Show with System.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.
