    I have i big big problem using a RadGridView and Entity Framework. As recently everything worked fine, but sine I've configured the last column correctly, the whole grid has turn read only and I can't even select a row.

    I'm afraid it will be terribly complicated to details here, but if you turn this into a support ticket I could send you a copy of the project.

    But to try to describe it:
    The form as a datasource:
                return from oo in this.DataContext.OnlineOrders
                       where oo.oo_Deleted == false
                       select oo;

    The grid has a datasource which is a subentity (this.DataContext.OnlineOrders.OnlineOrdersLine) from the selection here above.

    The first column is a GridViewComboBoxColum is receiving ("Another EF query").ToList() as datasource for list items. And always contains values.

    The last column, the one that seems to have just started the problem is a GridViewComboBoxColumn receiving ("Yet another EF query").ToList() as datasource for list items. And always contains blank/null at the start.

    (This kind of situation already revealed one or two bugs in the past that were corrected in the Q3 2011 and Q1 2012, as I was doing exactly what I need to do, but the RadGridView had some behavioural bugs when using the relatively new Microsfot .NET 'Entity Framework'. So I can't even be sure if it is my fault or RadGridView's.)

    Thank you for you help.
