I put this control on a grid and it dramatically reduces the rendering speed of the grid.  It takes noticeably longer to scroll down.

Am I doing something wrong?

Here is what I have added to the Grid.

<telerik:GridViewDataColumn  DataMemberBinding="{Binding Path=Rating}" Header="Rating" MinWidth="60" Width="SizeToCells">
                       <telerik:GridViewColumn.CellTemplate>
                          <DataTemplate>
                             <telerikInput:RadRating Name="_leadRating"  Value="{Binding Path=Rating,Mode=TwoWay}" UseLayoutRounding="True">
                                <i:Interaction.Triggers>
                                   <i:EventTrigger EventName="ValueChanged">
                                      <cmd:EventToCommand Command="{Binding Path=DataContext.ChangeRatingCommand, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl, AncestorLevel=1}}" CommandParameter="{Binding}" />
                                   </i:EventTrigger>
                                </i:Interaction.Triggers>
                             </telerikInput:RadRating>
                          </DataTemplate>
                       </telerik:GridViewColumn.CellTemplate>
                    </telerik:GridViewDataColumn>
