I see how to specify a dropdownlist for a column filter, however it appears to require a data source for the list items. Is it possible to specify that this data source be the unique values in the column being filtered on?
Thanks,
Gary

Hello Gary,
To achieve this you should manually handle the back end and return the distinct values for the specified column. For example in the MVC Filter menu customization demo, here is the controller action, that we are using for the cities column:
public ActionResult FilterMenuCustomization_Cities()
