The MS ComboBox and RadComboBox are interchangeable. So you can use either one. It really does not matter that much.
Anyway, the question now is: If you take these two lines of code and execute them the outside
RadDataFilter, i.e. in a simple SL page that has nothing but a ComboBox, does it work? This is very important.
Just create a new page, add a combo in the page and do the same thing.
What do you get. Is it working?
