I had the same problem and i made a solution and it works perfectly.
I made an own Xps Document class to set URI dynamically:
public class ManualXpsDocument : XpsDocument
{
private const string _uriOfDoc= "...\\path.xps";
public ManualXpsDocument(FileAccess fileAccess) : base(_uriOfDoc, fileAccess)
{
}
}
Here is the xaml part of window (or control):
<Grid.Resources>
<ObjectDataProvider x:Key="myDataSource" MethodName="GetFixedDocumentSequence"
ObjectType="{x:Type manual:ManualXpsDocument}">
<ObjectDataProvider.ConstructorParameters>
<io:FileAccess>Read</io:FileAccess>
</ObjectDataProvider.ConstructorParameters>
</ObjectDataProvider>
</Grid.Resources>
<DocumentViewer x:Name="Viewer" Document="{Binding Source={StaticResource myDataSource}}">
<DocumentViewer.Resources>
<Style TargetType="ToolBar">
<Setter Property="Visibility" Value="Collapsed" />
</Style>
<Style TargetType="{x:Type ContentControl}">
<Setter Property="Visibility" Value="Collapsed" />
</Style>
</DocumentViewer.Resources>
<DocumentViewer.Style>
<Style TargetType="{x:Type DocumentViewer}">

Here is The xaml.cs part of Window (or control):
public ctor()
{
InitializeComponent();
PreviewTouchMove += ScrollingHandler;
}
private void ScrollingHandler(object sender, TouchEventArgs e)
{
TouchPoint tp = e.GetTouchPoint(Viewer);
if (tp.Action == TouchAction.Move)
{
//_scrollingInt is not necessary but Move procedure of Viewer has const value to scroll and the optimalization is recommended.
if (_lastYPosition > tp.Position.Y + _scrollingInt)
{
Viewer.MoveDown();
_lastYPosition = tp.Position.Y;
}
else if (_lastYPosition < tp.Position.Y - _scrollingInt)
{
Viewer.MoveUp();
_lastYPosition = tp.Position.Y;
}
}
// Viewer.IsHitTestVisible = false; this setting can disable the selection too,but if you use this, the hyperlinks won't work too.
Viewer.GetType().GetProperty("IsSelectionEnabled", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(Viewer, false, null);
//set false "IsSelectionEnabled" "hidden" property instead of Viewer.IsHitTestVisible = false, because the hyperlinks will work too.
e.Handled = true;
}
ScrollingHandler method solve the problem. This procedure do the scrolling of document viewer and disable the selection but the hyperlink function still available.
