Hi Thangachan,

Thank you for posting in our forums.

Merging works only if you have the same values in a two adjacent columns. So in this case, since you have different values in your columns, it is not really applicable. What I would suggest to do in this case is to hide the empty columns and make the “Type” column larger. You can hide a column by setting its Hidden property to true and you can control its width from the Width property:

            ultraGrid1.DisplayLayout.Bands[0].Columns["EmptyColumn1"].Hidden = true;
            ultraGrid1.DisplayLayout.Bands[0].Columns["EmptyColumn2"].Hidden = true;
            ultraGrid1.DisplayLayout.Bands[0].Columns["Type"].Width = 200;

Please let me know if you have any additional questions.
