Click textbox to show popup, click outside to close popup

Question

I am designing a WPF usercontrol, and there is a textbox and a popup under the textbox. I want to click the textbox, then the popup shows. If I click outside of the textbox, the popup closes.

Now the problem is how to unfocus the textbox if I click outside the usercontrol area? Is any better way to design this control? Thanks.
