ToolStripButton.CheckStateChanged Event

Definition

Occurs when the value of the CheckState property changes.

public:
 event EventHandler ^ CheckStateChanged;
public event EventHandler CheckStateChanged;
member this.CheckStateChanged : EventHandler 
Public Custom Event CheckStateChanged 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 CheckStateChanged 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 ToolStripButton named ToolStripButton1. Then ensure that the event handler is associated with the CheckStateChanged event.

private void ToolStripButton1_CheckStateChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripButton.CheckStateChanged event.");

}
Private Sub ToolStripButton1_CheckStateChanged(sender as Object, e as EventArgs) _ 
     Handles ToolStripButton1.CheckStateChanged

   MessageBox.Show("You are in the ToolStripButton.CheckStateChanged event.")

End Sub
