    In my project I add a image on column's header to let user group or ungroup current column, in the same time I add some javascript to call Grid's client API fireCommand("UnGroupByColumn", "") and fireCommand("GroupByColumn", "") on these image's click event, when I click one columns' groupping image, grid will group or ungroup on this column.

    Currently groupping image's behavior is: [Group] -> [UnGroup] -> [Group] -> ..., Now, I want to midify their behavior with: [Group ascending] -> [Group descending] -> [UnGroup]
    So, how I can implement this function?

    I hope Grid's fireCommand can support the following function:
    fireCommand("GroupByColumn", "ContactName DESC");

    Hello Liu Peng,

    Thank you for contacting us and for your question.

    I am afraid that the fireCommand method does not support such a functionality.

    The best way to achieve the implementation you are considering is to use the AjaxManager ajaxRequest client method and handler your group by expressions on the server.

    For your convenience, I am sending you a small sample demonstrating how to achieve that.

    Please, use it for comparison with your implementation and let me know if I can help you further.

    All the best,
    the Telerik team
