So I've got a control that uses a radcombobox. Said control exists in two nearly identical pages, but on one of the pages it's empty. Doing a step through on the codebehind shows that the datasource is binding correctly and is populated with information.
So I'm left here scratching my head trying to figure out why the combobox on this one page is always empty. In both cases the combobox is in a separate table above a radgrid, and is loaded when the grid calls it's NeedDataSource function on postback (after search, the box is used to determine an action to take against an item in the list).
It looks as if everything is fine on the server side.
