Previously i used the Infragistics v6.1 .so i put the UltraGrid v6.1 in one windows form. i set the Allow Add New Property in the Ultra Grid. Then it worked fine and grid did not show any button in the Grid at run time when datasource is null. Now i upgrade to Infragistics v8.2 . but now the Grid show one star button at runtime when datasource is null. then i click that button , it shows one  "Data Error" like "Unable to add a Row: Not enough context to add a new row.Either a row in this band or parent band as to be active to provide for enough context." . This Problem occured after upgrade to Infragistics v8.2. How to resolve this problem ?
