0. suggest you put a Public Property in the UserControl code to track whether the Control is Visible and Active:

public bool HiddenOrLeft { set; get; }

Update that variable using the various EventHandlers described here:

1. use the 'VisibleChanged Event of the UserControl to detect when it is hidden.

2. use the 'Leave Event of the UserControl to detect it loses Focus on the Form it is sited in.

3. use the 'Enter Event of the UserControl to detect it becomes active/has focus.

4. use the Form 'Leave Event to also set the flag that indicates the UserControl is not active.

You want to go "whole hog:" also handle the /Form.Deactivated Event and the Form 'VisibleChanged Event
