ToolStripDropDown.Closed Event

Definition

Occurs when the ToolStripDropDown is closed.

public:
 event System::Windows::Forms::ToolStripDropDownClosedEventHandler ^ Closed;
public event System.Windows.Forms.ToolStripDropDownClosedEventHandler Closed;
public event System.Windows.Forms.ToolStripDropDownClosedEventHandler? Closed;
member this.Closed : System.Windows.Forms.ToolStripDropDownClosedEventHandler 
Public Custom Event Closed As ToolStripDropDownClosedEventHandler 

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 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 Closed event.

private void ToolStripDropDown1_Closed(Object sender, ToolStripDropDownClosedEventArgs e) {

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

Remarks

When you create a ToolStripDropDown delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Handling and Raising Events.
