Is it possible to have the vertical scroll bar visible?

We are using the PDF viewer in MouseMode PanTool.

The scroll bars are displayed automatically when the content does not fit into the viewing area.
I guess you need to set the PdfViewer to vertical viewing mode.
Code:

pdfViewer1.ViewMode = ViewModes.Vertical;

Thanks for the reply, unfortunately that doesn't work.

This is the only properties I'm setting:

pdfViewer.CanVerticallyScroll = true;
pdfViewer.CanHorizontallyScroll = false;
pdfViewer.MouseMode = MouseModes.PanTool;
pdfViewer.ViewMode = ViewModes.Vertical;

The PDF documents are display just as we would like i.e. full page width and then able to pan with the mouse/finger. It would be preferable to have a scroll bar present as well if possible.

Do you use WPF or WinForms?

Do you use it like shown below?
Code:

<ScrollViewer CanContentScroll="True"  VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
    <Wpf:PdfViewer Name="pdfViewer1" />
</ScrollViewer>

I've tried that and it's just the same.

I was going to attach a screenshot but I can't see the Attach button that is mentioned in the Forum help.

I've found out what is causing the issue.

We're overriding the styling of the scrollbar within the application. This works fine everywhere else in the application where a scroll bar is used. Once I take off the new styling then the scroll bar re-appears when viewing PDF documents.

We're developing a touch base application and therefore wish to present the scroll bar more similar to a mobile device.

I'll investigate the way it is restyled to try and determine what is causing the issue.

Thanks for your help.

None of these suggestions work for me. I simply cannot get the PdfViewer to scroll, as no scrollbar shows up. I can only use the mouse to pan it up and down. Here is my xaml declaration:

<ScrollViewer Grid.Row="1" CanContentScroll="True" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
<wpf:PdfViewer x:Name="Viewer" ViewMode="Vertical" CanVerticallyScroll="True" MouseMode="PanTool"/>
</ScrollViewer>
