Hello Michael,

Thank you for posting to our forum.

To apply the cell padding we do have cellpadding property which you can use it like this:

this.ultraGrid1.DisplayLayout.Bands[0].Override.CellPadding = 2;

But keep in mind this padding would be applicable to all sides of the cell.
There is no way to apply cell padding only to the right side.

Please let me know if you need further assistance.
