Displaying a large number of items may cause performance issues. In this case, it might be useful to use deferred scrolling. For more information, see Optimizing Performance: Controls.

This property can be used as an instance property and an attached property.

The following example shows a ScrollViewer with the IsDeferredScrollingEnabled property set to true.

<ScrollViewer Grid.Column="0" Grid.Row="0"  Height="200" Name="sv1"  IsDeferredScrollingEnabled="true">
    <TextBlock Text="1" Height="50"/>
    <TextBlock Text="2" Height="50"/>
