Answer 1

try this

var xpage = your user control or page to which scroll bar need to be added at runtime

            xpage.SetValue(ScrollViewer.CanContentScrollProperty, true);
            xpage.SetValue(ScrollViewer.HorizontalScrollBarVisibilityProperty, ScrollBarVisibility.Auto);
            xpage.SetValue(ScrollViewer.VerticalScrollBarVisibilityProperty, ScrollBarVisibility.Auto);

            var scrollViewer = xpage.Content as ScrollViewer;
            if (scrollViewer != null)
            {
                var content = scrollViewer.Content;
                scrollViewer.Content = null;
                xpage.Content = content;
            }
            else
            {
                var content = xpage.Content;
                xpage.Content = null;
                xpage.Content = new ScrollViewer { Content = content };
            }

You could add a ScrollViewer element to your window and put the necessary controls into the ScrollViewer control.

<ScrollViewer VerticalScrollBarVisibility="Auto">
    ...
</ScrollViewer>

Or if you want to code it in the code-behind file you could write

ScrollViewer viewer = new ScrollViewer();
viewer.VerticalScrollBarVisibility = ScrollBarVisibility.Auto;
// append scroll viewer to window

You cannot add a scrollbar to a window itself. You can only add scrollbars to controls. I.E. to a grid inside your window.

Example:

<Grid  ScrollViewer.CanContentScroll="True"
       ScrollViewer.HorizontalScrollBarVisibility="Auto">
   ...
</Grid>

EDIT:

Just realized that Window also has a ScrollViewer property. I'm not sure how this property works for a Window and how such a window would look like. Gave it a try, but no scrollbars show up.

EDIT 2:

ScrollViewer sv = new ScrollViewer();
sv.VerticalScrollBarVisibility = ScrollBarVisibility.Visible;
myGrid.Children.Add(sv);
