At the current moment filter not working whit filter expresion. Use OnFilter event.
Filter dialog from RxDBGrid not work with TRxMemoryData.
In future i'm plan write code for this functional.

Maybe you can add "ISNULL" to ColumnFilter ValueList and done it?

It's don't work because you must add "break"
if Filter.IsNull then begin
Accept:=Field.IsNull;
break
end
