[Solved] Binding RadGrid to generic list

[Richard Branham]

I'm attempting to bind a generic list to a RadGrid.  This works:

            List<int> originList = new List<int>();

            originList.Add(24);
            originList.Add(328);

            myDataContext dc = new myDataContext();
            List<Leg_ListResult> legList = (from l in dc.Leg_List()
//                                               where originList.Contains((int)l.OriginWaypointID)
                                                select l).ToList();
            gridLegs.DataSource = legList;

But the following does not.  The only difference is the addition of 'where' in the LINQ code.  When I run in the debugger, the legList contains the expected number of records in both cases, but no records are displayed in the grid in when I bind after specifying the where condition.  Am I missing something?

            List<int> originList = new List<int>();

            originList.Add(24);
            originList.Add(328);

            myDataContext dc = new myDataContext();
            List<Leg_ListResult> legList = (from l in dc.Leg_List()
                                               where originList.Contains((int)l.OriginWaypointID)
                                                select l).ToList();
            gridLegs.DataSource = legList;

Hello Richard,

I don't see any reason why the code you use to not work as expected. For your convenience I've prepared sample application using scenario described in your post and it seems that RadGrid binds properly to the collection.

Please find the attached application.

All the best,

Thanks for the reply. 

The problem was with the AJAX configuration, which I think I failed to mention in my initial post.  I configured the AJAX manager to update the grid in question and the page works as expected.
