Hi Sheela, Normally this issue happens in the following reason. 1)Setting the ColWidths through Header Text (grid.Model.ColWidths["Header Text"] = 10) 2) If you are binding to any empty table that causing this issue ColWidths accepts either the column number or the mapping name. It will not accept the HeaderText. so try this, col.MappingName = "Name" grid.Model.ColWidths["Name"] = 10; // or grid.Model.ColWidths[5] = 10; // If it is added as the Fifth Column Let me know if this helps. Regards, Haneef
