Question

On my ListBoxItem MouseEnter event I am creating a new window with the following code.

Window w = new Window(); w.Show(); 

When the mouse leaves the current item I want to close the window.

How do I do that?

Many Thanks.

Store a reference to the window (w in your case) in a place where both the event handler for MouseEnter and MouseExit can access it and then just do a w.Close().
