  Hi,

  I am able to observe the discrepancy in row background upon scrolling the grid. However, upon debugging the application, the cause of this behavior was when model with AccountBackGround other than Plum/LightPink/Orange was passed there was no specific Style returned which is why the grid was showing randomly any Style. Returning a default style for else part fixed the issue at my end.

  public override Style SelectStyle(object item, DependencyObject container)
  {
         var model = item as DataItemComponent;
         if (model != null)
         {
             if (model.AccountBackGround == "Plum")
             {
                  return PlumCellTemplate;
             }
             else if (model.AccountBackGround == "LightPink")
             {
                  return LightPinkCellTemplate;
             }
             else if (model.AccountBackGround == "Orange")
             {
                  return OrangeCellTemplate;
             }
             [b]else
             {
                  return NormalCellTemplate;
             }[/b]
         }
         return null;
  }
  ```[b]Xaml[/b]```
  <[b]c:CheckResultStyleSelector.NormalCellTemplate>
       <Style TargetType="c1:DataGridCellPresenter">
          <Setter Property="Background" Value="{Binding C1DataGridExtension.RowBackground}" />
       </Style>
   </c:CheckResultStyleSelector.NormalCellTemplate>[/b]
  ```Please verify the fix using the attached modified sample application.
