Our client is complaining about RadGrid filtering functionality. The problem is that when they want to filter Grid by more than 1 column they have to click the button and experience postback (which takes time) every time they apply filter for another column. We need to overcome this somehow. Using RadFilter control doesn't seem to be a good solution because it also causes postback every time filter item is applied.
Do we have a workaround for this?
