You can make use of PagedCollectionView's PageChanging and PageChanged event: Store the SelectedItems in PagedChanging event and set the SelectedItems back in PagedChanged event.

C#

PagedCollectionView view;
List<course> selectedCourses = new List<course>();
public void OnLoadCompleted(LoadOperation<course> courses)
{
    view = new PagedCollectionView(courses.Entities.OrderBy(c => c.CourseID));
    view.PageSize = 5;
    //datapager
    page.Source = view;
    //datagrid
    datagrid2.ItemsSource = view;
    //event handler
    view.PageChanging += new EventHandler<system.componentmodel.pagechangingeventargs>(view_PageChanging);
    view.PageChanged += new EventHandler<eventargs>(view_PageChanged);
    //remove default selection
    datagrid2.SelectedIndex=-1;      
}

void view_PageChanged(object sender, EventArgs e)
{
    //remove default selection
    view.MoveCurrentToPosition(-1);
    if (selectedCourses.Count <= 0)
        return;
    //set the selected items
    for (int i = 0; i < view.Count; i++)
    {
        if (selectedCourses.Contains(view[ i ] as Course))
            datagrid2.SelectedItems.Add(view[ i ]);
    }      
}

void view_PageChanging(object sender, System.ComponentModel.PageChangingEventArgs e)
{
    //store selected items
    if (datagrid2.SelectedItems.Count > 0)
    {
        for (int i = 0; i < datagrid2.SelectedItems.Count; i++)
        {
            if (selectedCourses.Contains(datagrid2.SelectedItems[ i ] as Course))
                continue;
            selectedCourses.Add(datagrid2.SelectedItems[ i ] as Course);
        }
    }
}</eventargs></system.componentmodel.pagechangingeventargs></course></course></course>
