Hello,
I'm using the VirtualQueryableCollectionView with a RadGridView and it works fine; the problem that I have is when I open the filter control the list of distinct values is empty (as shown in the attached file).
Do they never show up with the virtual collection or does there exist some event where I can hook up and fill this list by my own?
Because I would like to avoid to implement my custom filter control and have to manage all this filterdescriptors stuff...
Regards

You could use the DistinctValuesLoading event of the RadGridView to load DistinctValues. This help article shows an example on how to use this event.

Hello,
thanks for the answer; I tried it out and if I specify a "static" List of items it works correctly; but if I load the distinct values on demand in the event handler from a RIA Service it does not work.
I solved the problem now by implementing a custom filter control.
Thanks
