If I have a RadGrid which has a column that can have A, B, C or blank displayed in the column and I enable it to be a filtered column with a check box. 

Can I assign a value to value to show up in the popup menu for blanks?

so for example instead of

[ ]

[ ] A

[ ] B

[ ] C

I would see the menu displayed as

[ ] Empty

[ ] A

[ ] B

[ ] C

Hi Ed,

If you are using the CheckList or Excel-like filtering modes provided by RadGrid, you can modify the source passed to the e.ListBox in the FilterCheckListItemsRequested event handler:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/filtering/checklist-filtering

I hope this will prove helpful.
