    I have used a custom column in my grid which contains a radprogressbar (from an example on here! see below)

    When I used this column the first time the grid displays the progress bar values do not display correctly (see picture 1), then after I sort one by clicking one of the column headings the progress bar displays the correct values (see picture 2)

    Any idea why this would happen?  The XAML is also below

    <local:GridViewPercentageColumn DataMemberBinding="{Binding Turnaround, Mode=TwoWay}" DataFormatString="{}{0}%" Header="{Binding Path=CellPathResource.Turnaround, Source={StaticResource ResourcesWrapper}}" />

    #region PercentageColumn
     
       public class GridViewPercentageColumn : GridViewDataColumn
       {
           public override FrameworkElement CreateCellElement(GridViewCell cell, object dataItem)
           {
               var bar = cell.Content as RadProgressBar;
     
               if (bar == null)
               {
                   bar = new RadProgressBar();
                   bar.Height = 20;
                   bar.Foreground = new SolidColorBrush(Colors.Green);
                   bar.SetBinding(RadProgressBar.ValueProperty, this.DataMemberBinding);
                   cell.Content = bar;
               }
     
               return bar;
           }
     
           public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem)
           {
               var slider = new RadSlider();
               slider.Maximum = 0;
               slider.Maximum = 100;
               slider.SmallChange = 1;
               slider.LargeChange = 10;
               slider.SetBinding(RadSlider.ValueProperty, this.DataMemberBinding);
               return slider;
           }
       }
     
       #endregion

    Hi Cameron,

    I tried to reproduce the issue you reported, but still without any success. Could you take a look at the sample attached and let me know whether you can get the same behavior on it ? Am I missing something ?
