UserControl.AutoValidateChanged Event

 

Occurs when the AutoValidate property changes.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(true)]
public event EventHandler AutoValidateChanged

If your custom control performs any of its own validation, you will need to know when a developer using your control has changed the AutoValidate property so that you can change your control's validation behavior accordingly.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the AutoValidateChanged 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 UserControl named UserControl1. Then ensure that the event handler is associated with the AutoValidateChanged event.

private void UserControl1_AutoValidateChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the UserControl.AutoValidateChanged event.");

}
