GridMultiColumnDropDownList missing ItemsSourceSelector

[Ondrej Svoboda]

Hi,

I'm missing ItemsSourceSelector in GridMultiColumnDropDownList. I need to filter items source values based on some other row value. (something you have in your docs - filter cities by country).

Is there some other way how to do it?

Thanks
