TVirtualDataTable.GetDistinct Method
Override this method to return a new VirtualDataSet with unique values. Note that the returned dataset will not have all the columns this one has, only the ones defined on "filterFields"
Remarks
You do not need to implement this method if you do not want to let users create "Distinct()" filters on the config sheet.
