    Hi!

    I have a large GridView with a lot of columns and it is very slow when filtering.
    If I open the filter popup for a column and selects a checkbox in the distinct values list it will automatically filter my grid immediately.
    This will take a couple of seconds and the UI will lock up.

    Instead I would like the user to be able to check several items first, without filtering the grid.
    Then when the user press the Filter button it will do the filtering once.

    I guess this is not simply achieved out of the box, but how much retemplating or modifications do I need to make?
    Is there any behavior or something I can attach?
    Can I easily make my own filtercontrol?

    - Regards,
    Håkan

    Hello Håkan,

    In order to filter only on the Filter button click, you need to set IsFilteringDeferred="True" for the columns.

    Let me know how this works for you.
