Scroll WPF Listview to specific line

Question

WPF, Browserlike app.
I got one page containing a ListView. After calling a PageFunction I add a line to the ListView, and want to scroll the new line into view:

Answer 1

Try this

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            ScrollViewer scrollViewer = GetScrollViewer(lstVw) as ScrollViewer;
            scrollViewer.ScrollToHorizontalOffset(dataRowToFocus.RowIndex);
            if (dataRowToFocus.RowIndex < 2)
                lstVw.ScrollIntoView((Entity)lstVw.Items[0]);
            else
                lstVw.ScrollIntoView(e.AddedItems[0]);
        } 

 public static DependencyObject GetScrollViewer(DependencyObject o)
        {
            if (o is ScrollViewer)
            { return o; }

            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(o); i++)
            {
                var child = VisualTreeHelper.GetChild(o, i);

                var result = GetScrollViewer(child);
                if (result == null)
                {
                    continue;
                }
                else
                {
                    return result;
                }
            }
            return null;
        } 

private void Focus()
{
 lstVw.SelectedIndex = dataRowToFocus.RowIndex;
 lstVw.SelectedItem = (Entity)dataRowToFocus.Row;

 ListViewItem lvi = (ListViewItem)lstVw.ItemContainerGenerator.ContainerFromItem(lstVw.SelectedItem);
ContentPresenter contentPresenter = FindVisualChild(lvi);
contentPresenter.Focus();
contentPresenter.BringIntoView();

}
