  1. <DataGrid x:Name="DG_myStudents" RowDetailsVisibilityMode="Visible">    
  2.         <DataGrid.RowDetailsTemplate>    
  3.             <DataTemplate>    
  4.                 <DataGrid x:Name="DG_myMarks" ItemsSource="{Binding myMarks}" />    
  5.             </DataTemplate>    
  6.         </DataGrid.RowDetailsTemplate>    
  7. </DataGrid>  
Nothing, the nested datagrid "DG_myMarks" is not showing any data. And when i bind "myMarks" to a label to just to see any thing happening there, then label is showing "Marks class name" like this "MyNameSpace.myPage+Marks"
