    Hi Santhosh,

    We are sorry but this issue is not reproducible at our end. Could you please share the C1 version you are using?

    In case you are using an old version, could you please try the same with the latest build (4.5.20203.727) and see if the issue happens or not? You can upgrade to the latest build using C1ControlPanel from here :

    Hi Karthik,

    We are using 4.5.20202.716, we are also not able to reproduce the scenario exactly so that, i didn't able to create a sample for your reference. I think there is a problem while calling the System.Windows.Media.Visual.PointToScreen(Point point) method while dragging the dockcontrols., what my assumption is, it needs some validation before calling the PointToScreen method, will you please check on it meanwhile, i will try with the latest build.

    Thanks & Regards

    And also are you performing any specific operation during the docking operation? If yes then please make the necessary changes in the attached sample.
