    Hi,
    We are using Telerik RadDocking control within our main framework window. The RadDocking contains RadSplitContainers that has a RadPaneGroup with RadDoumentPane and RadDoumentPane.content 

    Description: 
    The content (RadDoumentPane.content) is WPF user control for to Displaying Data.
    The data we display is rendered by some graphic component, using DirectX to render images on the Rad panel control.

    This graphic component is writen in native C++/MFC, and is informed of the hosting WPF application window through its handle, in addition to the location of the Rad panel control. When given the order, this component is creating a window, to which it renders all its content,
    placing that window exactly on the same location that we give (the location of the Dock panel). 

    Issue:
    The problem starts when we're undock the panel. We then have to inform the graphic component on the change
    of host to the native window (when docked, the host is actually the main application window, but when undocked, it is rather the Docking panel itself). It seems that when we do that, we do get the native window to be hosted on the Dock panel (we see menus that belong to the native window, but no image is rendered on the native window.

    *when the control is docked all works fine.

    I think maybe it is a related issue
