MenuStrip.MenuDeactivate Event


Occurs when the MenuStrip is deactivated.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event EventHandler MenuDeactivate

When activated by the ALT key, the MenuStrip or ToolStrip typically neither take nor remove the focus from the control that currently has the focus. If there is a control hosted within the MenuStrip or a drop-down of the MenuStrip, the control gains focus when the user presses the TAB key. In general, the GotFocus, LostFocus, Enter, and Leave events of MenuStrip might not be raised when they are activated by the keyboard. In such cases, use the MenuActivate and MenuDeactivate events instead.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MenuDeactivate 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 MenuStrip named MenuStrip1. Then ensure that the event handler is associated with the MenuDeactivate event.

private void MenuStrip1_MenuDeactivate(Object sender, EventArgs e) {

   MessageBox.Show("You are in the MenuStrip.MenuDeactivate event.");
