VirtualQueryableCollectionView and Filtering on Distinct Values

[Pawel]

I found in documentation in section GridView/Populating with Data/Using Data Virtualization quote:

Filtering on Distinct Values is not fully supported when using VirtualQueryableCollectionView. We suggest configuring with ShowDistinctFilters="False". That way only filtering through the Field Filters will be enabled. You can check the basic filtering section as a reference on the filtering support. There you can also find more information on how to filter through the Field Filters.

What mean, in details, "is not fully supported"? How it reveals?

How can I cope with it? Maybe loading data separately for Distinct Values section using OnRadGridViewDistinctValuesLoading event can help?(gridview-filtering-howto-display-all-distinct-values)?

Hi,

This means that the user will only be able to filter on the distinct values that are displayed into view. 
That is why, in order to avoid any misunderstanding, we suggest you to filter with the field filters.

Indeed, you are right and you can try loading the distinct values with your own custom logic when the DistinctValuesLoading event is raised.
