Thanks Mike, exactly what I was looking for. And no, the rows are not many. So this works.

Thanks Andrew for the direction.

The Checkbox column is unbound, how can I tie to the data item or the row selection? I do not see anything in UltraGrid.Selected.Rows (count is 0). I don't think it is tied to either of these.
 
(I am very new to this infragistics controls, please excuse me if any of this sounds silly)
