How to remove DocumentViewer drop-shadow?

Question

How can I remove the drop-shadow from the DocumentViewer control?
If I use docViewer.ShowPageBorders = false the normal border around the document is gone too. When I set a BorderBrush the border goes around the control and not the document.
Here is a screenshot of what I mean:

Any idea how I can do this?

Answer 1

I achieved it by creating my own style which overrides the built in style (along with ShowPageBorders="False"):

<Style TargetType="{x:Type DocumentPageView}">
    <Setter Property="OverridesDefaultStyle" Value="True" />
    <!-- custom styles here -->
</Style>

By using a custom Template for your DocumentmentViewer you can change how it all looks even more.
