I have Grid with country column here i need to apply filter for this column and also i need to make that filter as Combo Box.
How to bind data for that but not static data.How to implement this?
If your RadFilter is bound to your RadGrid, then the static data that is bound to the grid should still be filtered with the filter. If you would like to understand how to implement a RadFilter then you should refer to the documentation:
