Thanks Haneef,
The solution is working .But I have implemented
bmsdgHierarchyMapping.TableModel.Model.CoveredRanges.Add(GridRangeInfo.Cells(1, 1, 1, 4));
bmsdgHierarchyMapping.TableModel.Model.CoveredRanges.Add(GridRangeInfo.Cells(1, 5, 1, 8));
bmsdgHierarchyMapping.TableModel.Model.CoveredRanges.Add(GridRangeInfo.Cells(1, 9, 1, 12));
As my newly column is at position 2..the earlier settings are vanished and then I am not able to acheive the GridCovered Ranges.
Please help .
sample exe will be useful.
Thanks in Advance
