    Hello.

    I use control GridView (RadControls for WPF v2013.1.403.4 (Dev))
    As source I bound ObservableCollection.
    Sometimes after hard manupulating with data in my ObservableCollection I get duplicates in Grid rows.
    In such case I can see that collection GridView.Items contains duplicates but in the same time ObservableCollection is ok.

    DataLoadMode has default value (is it "Synchronous" ?).

    I see topic with similar problem (http://www.telerik.com/community/forums/wpf/gridview/radgridview-duplicates-data-from-observablecollection.aspx).

    Please could you advice me which way I can fix my problem (may be it is fixed in new version of control).
    Thank you.

    Hi Yordanka,
    unfortunately I do not have clearly actions for reproduce it.

    In my case duplicates happen after :
    View.MyBoundToGridCollection = new ObservableCollection<MyEntity>(myEntityList);

    But it is a floating error, sometime happens, sometime do not.

    As I can see in old topic ((http://www.telerik.com/community/forums/wpf/gridview/radgridview-duplicates-data-from-observablecollection.aspx)
    users got similar problems in previous version of telerik controls, and Telerik wrote that "This is a known bug which manifests in some scenarios"
    Please could you find out if mentioned bug was fixed or not ?

    Thank you

    Hello Pavel,

    The problem with Asynchronous load mode and duplicated items has been fixed and it is not reproducible with our latest official version Q2 2013 SP1.
