Maintain scroll position on treelistview page navigation

[Vinod]

  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.

Hi Vinod,

You can take a look at this help topic about more information how to scroll to a particular item (or item index) and column (which in fact is a cell).
