Hello,
when a GridView has no items to display, the funnels for the filters are not displayed, excepted for custom filters.
This poses problem for some cases. In my case, I have a custom filter that descends from FilteringControl. In the Prepare method, I call the inherited Prepare method and it raises an InvalidOperationException exception, with the following text: A column without EffectiveFilteringType cannot supply AvailableFilterOperators.
