WPF ScrollViewer偏移量设置

//获取scrollViewer的偏移量

private void scrollViewer1_ScrollChanged(object sender, ScrollChangedEventArgs e)
{
offsetValue = e.HorizontalOffset;
border_Left.Margin = new Thickness(offsetValue, 20, 0, 0);

offsetTop = e.VerticalOffset;
border_top.Margin = new Thickness(20, offsetTop, 0, 0);
}

 

//根据Grid大小改变设置scrollViewer的偏移量

private void Grid_SizeChanged(object sender, SizeChangedEventArgs e)
{
scrollViewer1.ScrollToHorizontalOffset(grid_1.ActualWidth - LayoutRoot.ActualWidth + 200);

//scrollViewer1.ScrollToVerticalOffset(grid_1.ActualHeight - LayoutRoot.ActualHeight);
