ToolStripMenuItem.CheckedChanged Event


Occurs when the value of the Checked property changes.

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


The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the CheckedChanged 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 ToolStripMenuItem named ToolStripMenuItem1. Then ensure that the event handler is associated with the CheckedChanged event.

private void ToolStripMenuItem1_CheckedChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripMenuItem.CheckedChanged event.");

Private Sub ToolStripMenuItem1_CheckedChanged(sender as Object, e as EventArgs) _ 
     Handles ToolStripMenuItem1.CheckedChanged

   MessageBox.Show("You are in the ToolStripMenuItem.CheckedChanged event.")

End Sub
