The best option in this case is to set a left padding. This can be done when handling ViewCellFormatting
to affect also the header cell. Consider the following sample:
|void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
| e.CellElement.Padding = new Padding(5, 0, 0, 0);
I hope this helps. If you have further questions, I will be glad to answer them.
