Is view state required to perform muti-column filtering? If not, can someone point me to a decent demo of multi-column filtering with view state is disabled. The 2013 Q1 update broke all of our grids where we disabled view state for performance gains and we were able to have multi column filtering. This is a BIG step backwards if view state is required.

Hi,
Yes, Multi-Column filtering is not supported with ViewState disabled. The behavior you were using in the previous version was caused by a bug in the functionality that disables the ViewState. In the previous version the ViewState was only disabled for the MasterTableView object not for the whole Grid and that is why the filtering was working. Now, the bug and this breaks the functionality.
On the other hand when you have EnableViewState set to false you may not get the performance gain that you are expecting. Yes, you lower the memory consumption of the browser, but you are firing request to the database on each and every postback because the data could not be reloaded from the ViewState and this could prolong the response from the server.
I hope the provided information helps.
Kind regards,
