Default Extending DataGridItem

Hi,

I am using the Row-Selectable DataGrid Control http://aspnet.4guysfromrolla.com/articles/072104-1.aspx and wanted to extend it with the feature that a datagriditem "remember" it's selected Status.

Code:
public class PrettyDataGridItem : DataGridItem, IPostBackEventHandler
{
   public PrettyDataGridItem(int itemIndex, int dataSetIndex, 
              ListItemType itemType) : base(itemIndex, dataSetIndex, itemType) {}

   public void RaisePostBackEvent(string eventArgument)
   {
      CommandEventArgs commandArgs = new CommandEventArgs(eventArgument, null);
      DataGridCommandEventArgs args = 
                     new DataGridCommandEventArgs(this, this, commandArgs);
      base.RaiseBubbleEvent(this, args);
   }

   public bool IsSelected
   {
      get{return ViewState["IsSelected"+UniqueID];}
      set{ViewState["IsSelected"+UniqueID] = value;}
   }
}
But if the PrettyDataGrid builds it's items hierarchy the DataGridItem looses the Value....and I don't know why

can somebody help me?
