Maintain scroll position on treelistview page navigation

[Manishkumar]

Hi,

I need to maintain scroll position (both horizontal and vertical) when moving across pages.
I tried the following code , but was unable to achieve the desired functionality.
Even after calling RestoreScrollPosition() the scrollviewer didn't change its position.

 

private void btnNext_Click(object sender, RoutedEventArgs e)

 

{

SetScrollPosition();
BindData();

RestoreScrollPosition();

 

 

 

}

 

 

private void SetScrollPosition()

 

{

 

GridViewScrollViewer svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();

 

 

 

_dbVerticalOffset = svSummaryInfo.VerticalOffset;
_dbHorizontalOffset = svSummaryInfo.HorizontalOffset;
}

private

 

void RestoreScrollPosition()

 

{

GridViewScrollViewer

 

svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();

 

 

if (svSummaryInfo != null)

 

  {

 

   svSummaryInfo.ScrollToHorizontalOffset(_dbHorizontalOffset);

   svSummaryInfo.ScrollToVerticalOffset(_dbVerticalOffset);

   }
}

Please provide a code snippet for the same.
