CheckBox.CheckStateChanged Event

Definition

Occurs when the value of the CheckState property changes.

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

Event Type

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 CheckBox named CheckBox1. Then ensure that the event handler is associated with the CheckStateChanged event.

private void CheckBox1_CheckStateChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the CheckBox.CheckStateChanged event.");
}
Private Sub CheckBox1_CheckStateChanged(sender as Object, e as EventArgs) _ 
     Handles CheckBox1.CheckStateChanged

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

End Sub
