    I have a simple implemation using the RadGridView that when you sort Asc and then Desc, i.e. cycle thru, you start to see duplicate rows appear. The Data does not  have duplicate rows so is a UI issue. I do not have any custom sorting and the sorting is on a text column, Company Name.

    Has anyone else seen this behavior and is there a work around to fix it??


    Version: 2011.1.419.1040

    THis is the usage: (I have removed the HeaderMenu, and ScrollMode with no change)

             <telerik:RadGridView Name="RunSheetGrid"
             telerikGridViewHeaderMenu:GridViewHeaderMenu.IsEnabled="True" Margin="0,22,0,0"
             RowStyleSelector="{StaticResource pendingRowStyleSelector}"

    Hi Jason Taylor,

    Our RadGridView controls for WPF and Silverlight share a common code base. However that is not the case with RadGridView for Winforms. In order to get better and timely support I would strongly advice you to post related to RadGirdView for Winforms in the relevant forum section.

    Kind Regards,

    Hi everyone,

    I'm having the same issue in a WPF project. Have any of you found a solution to this or another explanations about why it is happening?

    Hi Vlad,

         We have been using RadGridView Control of Silverlight in our application.Our RadGridView uses  'VirtualQueryableCollectionView' as its Itemsource.
         But when we use the sorting functionality of any column, some of the rows gets duplicated.
         We are currently using Telerik version "2014.1.331.1050".

    Hello Abhishek,

    Could you please open a support ticket or post in a new thread that describes your problem? This thread refers an issue that was reproducible with a 2011 version of our controls. As far as I can see, you are using a 2014 version. Since our product has changed a lot for the past 3 years, I guess that your issue will be addressed much more adequately out of this outdated context. It will be great if you can provide a sample project that we can debug on our side. Thank you.
