Scrollviewer reset when setting row.IsExpanded

[Sharada]

In the treelistview row loaded event , when I am trying to expand a tree node programatically,the scrollviewer resets.

 

private void rtSummaryInfo_RowLoaded(object sender, RowLoadedEventArgs e)

 

{    

 

        TreeListViewRow

 

lobjTreeListViewRow = (e.Row as Telerik.Windows.Controls.TreeListView.TreeListViewRow);

 

 

        SummaryData lobjSummaryData = (e.Row as Telerik.Windows.Controls.TreeListView.TreeListViewRow).DataContext as SummaryData;

 

 

        if (_lstExpandedNode.Contains(lobjSummaryData.NodeName))

 

        {

     

 

          lobjTreeListViewRow.IsExpanded =

true;  // at this point, scrollviewer gets resets 

 

        }

}

I need to maintain the scroll position while expanding a node. Your help is appreciated.
