Thank you for writing.
You can use the CellFormatting event of the RadGridView. Consider the following code snippet which demonstrates this:
, 10, FontStyle.Bold)
e.ColumnIndex = 1
Note that the creation of a Font is a heavy operation and can lead to memory leaks. It is best to create one font and use it across the application.
I hope this will help you. If you have further questions, I would be glad to help.
