    Dear Telerik Community.

    We are using the Silverlight Telerik control GridView in combination with the Persistence Framework.
    We use the nice GridViewCustomPropertyProvider from the samples, to be able to save the layout and settings of the grid.
    This works fine.

    Due to the fact, that the grid is 3 times the size wider than a normal monitor here, it is horizontaly scrollable.
    We also have the ColumnGroups in use, which seem to have a bug after loading from the persistence framework.

    Scrolling with ColumnGroups works, after the RadGridView is restored from persistence, it is broken. The position of the ColumnGroups seperators(?) is no longer matching the correct position.
    If i reset the persistence settings and reload the page without any settings applied, it works again. So i assume there is some kind of property set, which seems to be wrong or making trouble.

    Could you please have a look at this?

    I have made a screenshot showing the problem.

    Hi Florian ,

    It seems you have encountered a bug in RadGridView. May you please share the code relevant to restoring the column groups . I need to be able to reproduce it here and I will take care for the proper fix to be provided.

    Meanwhile as a workaround you may use a small hack to  perform  a "dummy" action to trigger  rearrangement of the common headers  e.g. add a fake column group to the column groups collection and remove it . A proper moment to do this would be after data has been loaded.

    Again any hints , code snippets etc. that may help us reproduce the issue in a local project would be highly appreciated.

    Kind regards,
