I'm experiencing some performance issues when setting the AllowDrag and AllowDrop with the RadGridView.
<UserControl.Resources>
<converters:LineBackgroundConverter x:Key="lineBackground"/>
<Style TargetType="telerik:GridViewRow">
<Setter Property="Background" Value="{Binding LineNumber, Converter={StaticResource lineBackground}}" />
<Setter Property="telerikDragDrop:RadDragAndDropManager.AllowDrag" Value="True" />
<Setter Property="telerikDragDrop:RadDragAndDropManager.AllowDrop" Value="True" />
</Style>
</UserControl.Resources>
