Yes, the WPF DataGrid has built in support for virtualization. By default theVirtualizingStackPanel .IsVirtualizing property is set to true, so by default the virtualization is used on the DataGrid, and you can specify the VirtualizingStackPanel.VirtualizationMode to either Standard or Recycling . 
By default, a VirtualizingStackPanel creates an item container for each visible item and discards it when it is no longer needed (such as when the item is scrolled out of view). When an ItemsControl contains a many items, the process of creating and discarding item containers can negatively affect performance. When VirtualizationMode is set to Recycling, the VirtualizingStackPanel reuses item containers instead of creating a new one each time.
For example, you can use Recycling mode like this:
<my:DataGrid AutoGenerateColumns="True" ItemsSource="{Binding}" Margin="11,20,8,9" Name="dataGrid1"
VirtualizingStackPanel.VirtualizationMode="Recycling" />

 

DataGrid.EnableColumnVirtualization
        若是啓用列虛擬化，則爲 true，不然爲 false。 註冊的默認值爲 false。
        https://msdn.microsoft.com/query/dev14.query?appId=Dev14IDEF1&l=ZH-CN&k=k(System.Windows.Controls.DataGrid.EnableColumnVirtualization);k(VS.XamlEditor);k(TargetFrameworkMoniker-.NETFramework,Version%3Dv4.0)&rd=true
        
DataGrid.EnableRowVirtualization
        若是啓用行虛擬化，則爲 true，不然爲 false。 註冊的默認值爲 true。
        https://msdn.microsoft.com/query/dev14.query?appId=Dev14IDEF1&l=ZH-CN&k=k(System.Windows.Controls.DataGrid.EnableRowVirtualization);k(VS.XamlEditor);k(TargetFrameworkMoniker-.NETFramework,Version%3Dv4.0)&rd=true

 

 

這樣設置會提升用戶體驗：

 

        <DataGrid ItemsSource="{Binding UserData}" 

                  EnableColumnVirtualization="True" 

                  EnableRowVirtualization="True"  

                  ScrollViewer.IsDeferredScrollingEnabled ="True"

                  VirtualizingStackPanel.IsVirtualizing="True"

                  VirtualizingStackPanel.VirtualizationMode="Recycling" 

                  AutoGenerateColumns="False">
