Window.Activated Window.Activated Window.Activated Window.Activated Event

Definition

Occurs when a window becomes the foreground window.

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

Remarks

A window is activated (becomes the foreground window) when:

  • The window is first opened.

  • A user switches to a window by selecting it with the mouse, pressing ALT+TAB, or from Task Manager.

  • A user clicks the window's taskbar button.

Windows that need to detect when they become activate can handle the Activated event.

After a window is first activated, it may be deactivated and reactivated many times during its lifetime. If an application's behavior or state depends on its activation state, it can inspect IsActive to determine which activation state it's in.

An application can also be Activated.
