I don't know for sure, but since you said "urgent", I'll shoot from the hip: I believe the Grid.DisplayLayout.LoadOnDemand property may do what you need. It's explained in the Online Docs (http://help.infragistics.com/NetAdvantage/NET/2008.2/CLR2.0/) on this page. (The first link requeres you to do a lot of navigation, the second is the frame contents you'll eventually find if you use the first link.)
