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
