Hello,
Use the UniqueName to access the cell in a particular column and apply the format from code behind based on the condition. The online help documentation shows how to access cells in grid.

I already tried this. The cell does not have the dataformatstring. The column does. I need a way to get a reference to the column itself so I can access the dataformatstring property. I don't how to do this using that link you sent.

Hello Levi,
The table cells do not know which column they belong to, but you can target a row's cell by using the column's UniqueName. If you want to use the ItemDataBound event handler to apply conditional formatting based on DataFormatString, then loop through the columns (not the cells) and use the columns' UniqueNames to target specific cells. For example:
(the DataFormatString in this case is empty, because it is not set)
