Examples

The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the Closing 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 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 ToolStripDropDown named ToolStripDropDown1. Then ensure that the event handler is associated with the Closing event.

private void ToolStripDropDown1_Closing(Object sender, ToolStripDropDownClosingEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "CloseReason", e.CloseReason );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Closing Event" );
}

Private Sub ToolStripDropDown1_Closing(sender as Object, e as ToolStripDropDownClosingEventArgs) _ 
     Handles ToolStripDropDown1.Closing

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "CloseReason", e.CloseReason)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Closing Event")

End Sub
