And I try the way to use PagedCollectionView to my behind code .cs,but when I try to write:

PagedCollectionView view=new PagedCollectionView();

and the data is from the database ,and load by the way DomainDateSource ,and I search from the Internet,they often put a name of a List in the bracket,but I don't got a List ,how can I do to group the data?
Here is same code of my xaml,and I am badly in need of help!!!

<riaControls:DomainDataSource Name="studentDataSource" LoadSize="20" QueryName="GetSMBasicInfoes" AutoLoad="True">

<data:DataGrid Name="dataGrid1" ItemsSource="{Binding Data, ElementName=studentDataSource}" AutoGenerateColumns="False">
