Hi
Mike,
Thanks
for using Syncfusion products.
We
analyzed your query and you can achieve your requirement by setting the
EnableLegacyStyle=”True” in GridDataControl.
In
our upcoming release volume 3,we changed the Filter Button behavior
to differentiate Filtered Columns and Non Filtered Columns, Which will be available
in mid of August, 2012.
Please
let us know if you have any concerns.
Regards,
Santhosh.A
