A way to filter distinct values at gridview filter popup

[Mustafa Erhan]

Hi All, 

I Have a gridview, which I enabled filter by FilteringMode.Popup. popup listing all the distinct values. How can I allow user to filter there distinct values or search within them ? Maybe something like dropdown beaviour may help, I mean when user types beginning of the value and the scroll goes to first item matches within the list. Have any option to do that ?
