When the user filters the dataSource, I would like to modify that filter before it gets sent to the server. Where and how can I do this? I am guessing the data event handler function is an appropriate place, but I tried that and it didn't work for me - I modified the filter and set it using filter(), but then it just resubmits the query and the data event handler is triggered again.
How can I do this?
Thanks,
