Silverlight Treeview with pages

I made a treeview with pages. Hope it helps anybody...


XAML:
A treeview and a Datapager


 
 

 
C#:

//ini
private Int16 _ElementsPerPage { get; set; } //The items per page
private ObservableCollection _Coll{ get; set; }

//onload
_ElementsPerPage = 250; //set the items you want per page
dataPager1.PageSize = _ElementsPerPage;

PagedCollectionView PC1 = new PagedCollectionView(_Coll);
dataPager1.Source = PC1;



//the event handler of the datapager
private void dataPager1_PageIndexChanged(object sender, EventArgs e)
{
ObservableCollection tcol =
  new ObservableCollection(_Coll.Skip(_ElementsPerPage * dataPager1.PageIndex).Take(_ElementsPerPage));

treeView1.DataContext = tcol; //bind to treeview 
}
