I've been trying to get the Filter Template on the grid to work with a RadComboBox, but have not been successful. I'm binding to a dataset which is a little different than the example at Filter Template Example. The dropdown seems to load correctly the first time, but then when I make a selection it fails. I'm guessing it's in the client code because it never gets back to the .
I'm getting the error:
Selection out of range
Parameter name: value
Below is my code:
Note, in the example you have the rebind that I've commented out above. When I do this, my ComboBox comes out empty. If I leave it out, then I get the values in the Combo Box.
I'm having a secondary problem with the ComboBox itself. Sometimes, the text in the is huge, other times it's the right size. I have no idea what's causing this.
