    The filter is very, very slow for everyday use against a radgrid. 

    It seems that a postback is created whenever an expression is added, when a field is selected and again when the operator is selected.  To do a simple filter for a last name "containing" it goes through 3 post backs.  Is there a way to speed this up?  Am I missing something?

    Hi Rob,

    Indeed, these three operations require three postbacks. The best way to improve the performance in this case would be to ajaxify the control as demonstrated in our online demos.
    For your convenience I performed a quick test to check what happens in terms of performance. You can see the results below (also in the attached screenshot)

    Request 1: 15.6 kb 393 ms
    Request 2: 15.8 kb 422 ms
    Request 3: 20.5 kb 432 ms

    Total: 51.9 kb for 1.25 sec for all three requests

    Let me know whether ajaxifying the control helps in your case.

    Best regards,
