I am in the init row event, and I am trying to make the font in certain cells bold. How do I do that?
You can do this using the Appearance property on the cell. The Appearance has a FontData property where you can define font properties like Bold.
I recommend that you take a look at the WinGrid Performance Guide.
There is a section in the guide called "Re-Use Appearances" which discusses how to apply appearances to cells in the most efficient way.
