How to Access ScrollViewer of WPF WebBrowser Component

How can I reference and change the settings for the ScrollViewer of a WebBrowser component of a C#/WPF/XAML form from the backing C# code?

            <WebBrowser ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                        ScrollViewer.VerticalScrollBarVisibility="Disabled"
                        ScrollViewer.CanContentScroll="False"
                        HorizontalAlignment="Stretch" VerticalAlignment="Stretch" 
                        Name="BrowserForm"  />

For example, the following isn't defined:

this.BrowserForm.ScrollViewer.HorizontalScrollBarVisibility

I tried accessing the ScrollViewer from the VisualTreeHelper, but the following returns 0:

VisualTreeHelper.GetChild(this.BrowserForm, 0)

That syntax doesn't work because you are setting an attached property (MSDN).

To set it in code, you have to utilize the static method defined by the class defining the property, in this case ScrollViewer.SetHorizontalScrollBarVisibility

ScrollViewer.SetHorizontalScrollBarVisibility(MyBrowser, ScrollBarVisibility.Visible);

Note: WebBrowser does not appear to actually be affected by this property, in XAML or in code, but this concept is correct. You may want to try wrapping your WebBrowser inside of a ScrollViewer if you want more control over scrolling.
