    Gridview is databound manually in runtime from EntityFramework,i cant see data aboute row groups in gridview column

    <telerik:GridViewColumn  CellTemplate="{DynamicResource Cell_RouteGroup}" Header="Group" Width="180" DataContext="{Binding RouteGroupDataSource}"></telerik:GridViewDataColumn>

            <DataTemplate x:Key="Cell_RouteGroup">
                <telerik:RadComboBox Height="29"  Width="118" Foreground="Black"  DisplayMemberPath="GroupName" SelectedValuePath="RouteGroupID" ItemSource={Binding RouteGroupSource}  SelectedValue="{Binding RouteGroupID}" />

     public IOrderedQueryable<Routes_Groups> RouteGroupDataSource
                get { return Loader.TEX.Routes_Groups.OrderBy(p => p.GroupName); }

    Hello amirnet,

    In your code I see that you are defining the ComboBox in a template explicitly.  There is no need to do this. RadGridView provides a specialized column - the GridViewComboBox column. It would create the combobox and set bindings for you. You just need to define such column and set a few properties.
    The approach is described in details in  this article.

    In case you have further troubles , just send me your project and I will gladly modify it to fix the issue.

    *In order to attach the project files you will need to open a support ticket.

    Sincerely yours,
