Page DomainDataSource

![Silverlight RadDataPager Binding to DomainDataSource(images/RadDataPager_How_To_PageDomainDataSource_01.png)

If you are using the WCF RIA Services and the DomainDataSource, you probably know that the DomainDataSource.Data property is in fact an instance of the DomainDataSourceView class. This class implements a handful of useful interfaces:

• ICollectionView

• IEnumerable

• INotifyCollectionChanged

• IEditableCollectionView

• PagedCollectionView

• INotifyPropertyChanged

IPagedCollectionView is among them which lets you do the whole paging in the server. To do that add a DomainDataSource control to your page/window and connect the items control and the pager to it. Here you can see how to do this:

<riaControls:DomainDataSource x:Name="invoicesDataSource" 
                              AutoLoad="True" 
                              QueryName="GetInvoicesQuery"> 
    <riaControls:DomainDataSource.DomainContext> 
          <services:ChinookDomainContext/> 
    </riaControls:DomainDataSource.DomainContext> 
</riaControls:DomainDataSource> 
<ListBox Name="itemsControl" 
      ItemsSource="{Binding Data, ElementName=invoicesDataSource}"/> 
<telerikGrid:RadDataPager Name="radDataPager" 
             Source="{Binding Data, ElementName=invoicesDataSource}" 
             PageSize="10" 
             DisplayMode="All"/> 

Note that both the ListBox and the RadDataPager are bound to the Data property of the DomainDataSource.
