Public ReadOnly Property CloseReason As ToolStripDropDownCloseReason

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

Private Sub ToolStripDropDown1_Closed(sender as Object, e as ToolStripDropDownClosedEventArgs) _ 
     Handles ToolStripDropDown1.Closed

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

End Sub
