Inorder to enable filtering on pressing the Enter key, you would have to enable AutoPostBackOnFilter property for the the columns in your grid to true. AutoPostBackOnFilter
Autopostback is enabled, and filters work,
but i just want to capture this event in OnCommand handler as i do for Sort, Page.
But event "Filter" is fired only when filter is applied from menu item like Equal, Greater than etc..
For simple string filters it is not fired for me ((
