TextBoxBase.ReadOnlyChanged TextBoxBase.ReadOnlyChanged TextBoxBase.ReadOnlyChanged TextBoxBase.ReadOnlyChanged Event

Definition

Occurs when the value of the ReadOnly property has changed.

public:
 event EventHandler ^ ReadOnlyChanged;
public event EventHandler ReadOnlyChanged;
member this.ReadOnlyChanged : EventHandler 
Public Custom Event ReadOnlyChanged As EventHandler 

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ReadOnlyChanged 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 TextBoxBase, such as a TextBox or TextBoxBase. Then name the instance TextBoxBase1 and ensure that the event handler is associated with the ReadOnlyChanged event.

private void TextBoxBase1_ReadOnlyChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the TextBoxBase.ReadOnlyChanged event.");

}
Private Sub TextBoxBase1_ReadOnlyChanged(sender as Object, e as EventArgs) _ 
     Handles TextBoxBase1.ReadOnlyChanged

   MessageBox.Show("You are in the TextBoxBase.ReadOnlyChanged event.")

End Sub
