    Using a RadComboBox on a UserControl; compiled on Win7 x64 using VS2010 and executed on a WinXP. When the drop down on the combo box is activated the contents is behind the dialog box.

    This is limited to a UserControl opened in a RadWindow

      RadWindow host = new RadWindow();
      host.Content = (new UserControl1());

    If the UserControl1 contains a ComboBox then the dropdown appears behind the UserControl1 window.

    Hi Stephen,

    We will greatly appreciate a sample project of yours. It will definitely help us in further pinpointing and resolving the problem. Can you attach the sample project to this thread?  

    All the best,

    Turns out the problem is machine dependent and I can't duplicate it on other XP machines so there must be something wrong with the one I tested it on and it happened in a very simple case of a combo box on a window - I had thought it had to do with the complex nature of the application that I saw the problem in. Very strange but I don't know the history of the machine so I don't know how it might have gotten this issue.

    Hi,

     
    Unfortunately, all our attempts to reproduce the problem failed. We will need a sample project to address the issue and locate its source.


    Best wishes,

    We have also been experiencing the exact same problem for a while now sporadically.
    Our issue also is on Windows XP machines, and seems to occur more often (or only) on PCs with dual monitors.
    I created a very basic test project with only a radwindow containing a radcombo and the problem does happen there.
    You may have better luck reproducing the problem if you run the test connected to the test pc via remote desktop.
    One important thing to add, it does not seem to happen with Expression Dark theme.
    I did create a small test app but do not have it with me currently.

    With us:
    Compiled on WinXP x32 using VS2010 and executed on multiple WinXP boxes.
    it is sporadic but does happen on multiple machines.
