 DataTable dt = new DataTable();
 dt.Columns.Add("ID", typeof(int));
 dt.Columns.Add("Name", typeof(string));

@Victor, From looking at the dates, I'm late to the party. If you are reading this now, what these folks are trying to say is that you are mixing technologies unneccessarily. The ADO.Net objects have essentially been replaced by the EntityFramework, beginning in .Net 3.5.

To answer the question posed on 6/25/2011, the actual code would be something like this:

List results = SomeQueryResults.ToList();

And that's about it. Most of the rest of the work is done by the grid. you might have to override the OrderBy() function, but that might be it.
