VisualTreeHelper.FindElementsInHostCoordinates is not return controls from the window

[Anatoly Chekh]

Hello!

I have a question.
We use method VisualTreeHelper.FindElementsInHostCoordinates for finding all elements by mouse position.
In the Q1 Release this methods return window and child control.
But in the Q2 it's not return them.
How can I find all controls under mouse position in the window?

For more details, we use VisualTreeHelper.FindElementsInHostCoordinates(position, Application.Current.RootVisual)

Thanks, Anatoly Chekh.

Hello Alex,

Thank you for contacting us.
What we changed was that we moved the RadWindow's popups out of the VisualTree - that was a work-around intended for internal use only which we don't need anymore. What I would suggest you is to change all the places where you call this method to do one additional check - is the point in one of the opened windows. You could use the RadWindowManager class to access all the opened Windows.

Hope this helps.

Thanks, but RadWindowManager.GetWindows now return empty list (http://www.telerik.com/community/forums/silverlight/window/radwindowmanager.aspx) so we need to use ourself Manager.

Hello Anatoly,

You are correct that such an issue exists in the Q2 2011 release, but we managed to fix it in the internal build. You could also keep track of the opened windows yourself as you suggested.
