    DataGridVirtualizingCollectionViewSource Class
    In This Topic
    The DataGridVirtualizingCollectionViewSource class is the XAML proxy of the DataGridVirtualizingCollectionView class, which provides support for data virtualization.
    Syntax
    'Declaration
 
<TypeDescriptionProviderAttribute(MS.Internal.ComponentModel.DependencyObjectProvider)>
<NameScopePropertyAttribute("NameScope", System.Windows.NameScope)>
Public Class DataGridVirtualizingCollectionViewSource 
   Inherits DataGridVirtualizingCollectionViewSourceBase
    'Usage
 
Dim instance As DataGridVirtualizingCollectionViewSource
    [TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
public class DataGridVirtualizingCollectionViewSource : DataGridVirtualizingCollectionViewSourceBase
    Remarks
    Also known as "virtual mode" or "lazy loading", data virtualization provides smart deferred querying of data, support for asynchronous data fetching, preemptive loading, and query abort notifications to ensure a smooth and seemless experience that leaves applications responsive and prevents needless queries to data servers.
