    The Q3 version does not appear to support mulitple column sorting when bound to a CollectionViewSource.View or DataView. When attempting to sort one column in ascending order and a second column in descending order, it does not correctly apply the second sort. This functionality had worked with the Q1 version. Has this functionality been purposefully removed?

    Hi Scott Janouskovec,

    Thank you for reporting the problem.
    It is already fixed and the fix will be part of our next internal build. Unfortunately, we will not be able to include it in our upcoming Q32010 SP1 because it is in final stage of testing.

    I have updated your Telerik points accordingly.

    Do you have an estimated timeframe for when this fix might be included in a "public" release?

    I am having the same problem. Are you saying I need to use the latest internal build for this?

    Thanks,

    I have tested with the 2011.1.315.35 version and am able to reproduce this issue. Is there a new property that needs to bet set to enable the multiple-column sorting?

    Hi,

    We have tested the case and everything works fine with Q1 2011 binaries. Could you share more details about your grid and the collection it is bound to? Are there specific steps how to reproduce the issue?

    The sample code and steps to reproduce were provided in the original bug report. The RadGridView is simply bound to a System.Data.DataTable.DefaultView that consists of two columns and attempt to sort the first column in ascending order and the second column in descending order.

    Hi,

    I have just tried the test project provided by you and multiple sorting is working fine. Please, check this short video.

    It appears to work if the GridView.ItemsSource is set to either a DataTable or CollectionViewSource. However, if the GridView.ItemsSource is set to a DataView it does not work.

    Hello,

    We were able to reproduce the problem with multiple sorting and it was fixed immediately. The fix will be part of the next internal build on Monday.

    Thank you for the feedback. Your Telerik points have been updated.
