I am running this same example http://demos.telerik.com/aspnet-mvc/grid/filtering in debug mode. I am using Q3 2010. Here is the controller:
If action Filtering (server) returns no record, action _Filtering (ajax) is invoked. Why is that? Not sure if this is by design, but what if I dont want to the Ajax select method being invoked? Is there a work around?
To reproduce, enter "Q" in the textbox and press Apply.
