Vista - how to get focused item in a page

I've got a browser-like WPF app, and would like to know what element in
my page currently is focused.

There seems to be no 'currentfocus' element in a page, and I'm a bit
stumped how to get the current focus of my app/page.
Probably I'm missing something very obvious here

Can someone help?
Thanks,
Sam

Check out the static FocusManager::FocusedElement[1] property.

HTH,

I tried FocusManager.GetFocusedElement(), but it always returns null in
my case

I'll dig around the FocusManager some more tomorrow though, thanks.

I`d be interested in knowing about your findings on your FocusManager
digging...

In the mean-time, I did work around that "problem" by using the
Keyboard.FocusedElement property..

This solution is however far from perfect since the KeyboardFocus
"drops" when application becomes inactive (keyboard focus in another
application)...

Well, I didn't even start digging, since your post does contain my
answer: I was looking for the keyboard focus, thats exactly the one I
needed.

*scratches head* I got to check this, maybe I'll run into the same
problems.

Thanks,

Hi,

just thinking about the keyboard focus problem.
Your app must be (at least one time) active - then you will get the KF Element.
When another app gains the focus you will have no KF element - am I right?

Idea: track the KF element in the manner of "CurrentKeyBoardFocusElement".
When your app loses focus this element still points to the control which was focused before.
So this should be the element you are looking for - no matter if you are active or not.
