Hello!

My problem is that I am coding a UserControl. Is basically a textbox that when it get focus it opens a popup. The popup contains buttons, a grid and others. The popup also has its StaysOpen property to False and the IsOpen is set to true on the textbox previewmousedown event.

The thing is that once I click the textbox it opens but when I click outside the popup it does not close.

A strange behavios is that when I click a button inside the popup and then outside of it, it works normally. It closes.

What am I doing wrong?

Solution 1

The popup probably doesn't get focus when it is shown. The close action is performed when it looses its focus, but you cannot lose focus if you didn't get it in the first place.
As a solution you might want to set the focus on the popup. When you click the button on the popup you also give it focus but manually.

Good luck!

I can't set focus on a popup. Setting focus on any element inside the popup does not work.

It inherits Focusable from UIElement and I think that should be true.
