    I would like to replace the default "error" image that is used to denote and invalid column (see attached image).  What's the best way to do so?

    Hello Lawrence,


    You may predefine the template of GridViewRow and modify the error indicator element, as follows:
    <Grid x:Name="ErrorIndicator" HorizontalAlignment="Center" VerticalAlignment="Center" Width="16" Height="16" Visibility="Collapsed">
                                    <Path Fill="{StaticResource GridView_ErrorIndicatorBackground1}" Stretch="Fill" Margin="1" Data="M3,12.999999 L4,12.999999 5,12.999999 6,12.999999 7,12.999999 8,12.999999 9,12.999999 10,12.999999 11,12.999999 11,13.999999 10,13.999999 9,13.999999 8,13.999999 7,13.999999 6,13.999999 5,13.999999 4,13.999999 3,13.999999 z M11,11.999999 L12,11.999999 12,12.999999 11,12.999999 z M2.0000001,11.999999 L3,11.999999 3,12.999999 2.0000001,12.999999 z M12,10.999999 L13,10.999999 13,11.999999 12,11.999999 z M1,10.999999 L2.0000001,10.999999 2.0000001,11.999999 1,11.999999 z M13,2.9999992 L14,2.9999992 14,3.9999992 14,4.9999992 14,5.9999992 14,6.9999992 14,7.9999992 14,8.9999992 14,9.9999992 14,10.999999 13,10.999999 13,9.9999992 13,8.9999992 13,7.9999992 13,6.9999992 13,5.9999992 13,4.9999992 13,3.9999992 z M0,2.9999992 L1,2.9999992 1,3.9999992 1,4.9999992 1,5.9999992 1,6.9999992 1,7.9999992 1,8.9999992 1,9.9999992 1,10.999999 0,10.999999 0,9.9999992 0,8.9999992 0,7.9999992 0,6.9999992 0,5.9999992 0,4.9999992 0,3.9999992 z M12,1.9999999 L13,1.9999999 13,2.9999992 12,2.9999992 z M1,1.9999999 L2.0000001,1.9999999 2.0000001,2.9999992 1,2.9999992 z M11,0.99999994 L12,0.99999994 12,1.9999999 11,1.9999999 z M2.0000001,0.99999994 L2.9999998,0.99999994 2.9999998,1.9999999 2.0000001,1.9999999 z M2.9999998,0 L3.9999998,0 5,0 6,0 7,0 8,0 9,0 10,0 11,0 11,0.99999994 10,0.99999994 9,0.99999994 8,0.99999994 7,0.99999994 6,0.99999994 5,0.99999994 3.9999998,0.99999994 2.9999998,0.99999994 z" />
