1. Create a new project with RadGridView and bind it. 2. Set the DisableHtmlFormatting property for a column to false. 3. Handle the CellFormatting event and use the Text property to change the cell font. For example: e.CellElement.Text = "<html><b>AASA:</b><size=15><font='Comic Sans MS'><color=green>qwert qwertwe"; 4. Run the project and check the cell font.
