How to close the rad pane on mouse leave?

[Sherry]

HI,

 

I have a docking control with a single radpane in it.

I have a button which makes this rad pane active. and I want to do is that when the mouse goes outside the pane then the pane closes. But the problem is that if I move the mouse from center region to the header of the rad pane then the mouse leave event is considered which seems the radpane header is not part of the radpane?

How to achieve the correct behavior?

 

Thanks
