I am trying to figure out how to only display a single page at a time and when the user scrolls using a mouse, it scrolls through full page views (Not showing partials as you scroll up).

I was advised to do this in an email "You can call ScrollToPage method or increment/decrement CurrentPageIndex property". Is there any documentation on how to actually implement that and use it for C# WPF applications.

XAML:

Code:

<ScrollViewer Grid.Row="1" CanContentScroll="True"  VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
    <Wpf:PdfViewer Name="pdfViewer1" ViewMode="SinglePage" SizeMode="FitToSize" MouseWheel="pdfViewer1_MouseWheel" />
</ScrollViewer>


code behind:
Code:

private void pdfViewer1_MouseWheel(object sender, MouseWheelEventArgs e)
{
	var doc = pdfViewer1.Document;
	if (doc == null)
		return;

	if (e.Delta < 0 && pdfViewer1.CurrentIndex < doc.Pages.Count)
		pdfViewer1.CurrentIndex++;
	else if (e.Delta > 0 && pdfViewer1.CurrentIndex > 0)
		pdfViewer1.CurrentIndex--;

}
