    I have a RadLinearSparkLine control within a DataGridTemplateColumn of my DataGrid. After I scroll, the markers on the RadLinearSparkline seem to jump around to random spots (please see attached screenshots). How do I prevent this from happening?

      <sdk:DataGridTemplateColumn Width="Auto" MinWidth="100" CanUserReorder="False" CanUserResize="True" CanUserSort="False">
                    <telerik:RadLinearSparkline MinWidth="90" Height="20" Margin="5,4"
                                                ItemsSource="{Binding Uptake}"
                                                ShowMarkers="True" LineStroke="{Binding UptakeBrush}"
                                                AutoRange="False" MinYValue="0">

    Kind regards,

    Hi Chris,

    The problem you are observing is caused by the UI virtualization of the RadGridView. You can try turning off the GridView virtualization by setting EnableRowVirtualization to False. You can find more information in this topic in our help system.

    I will forward your report to our developers for further investigation. Meanwhile you can use the fix described above.
