My goal is to display the entire contents of a FlowDocument (that is, without paginating) in a column layout. It would have a fixed height, but the width would depend on the contents of the FlowDocument.

My problem is: FlowDocumentReader does not automatically resize to the contents of the FlowDocument. As you see in my XAML below, FlowDocumentReader.Width is 5000 units (just a large number that can accommodate most documents) -- when I make it Auto, it just clips to the width of the ScrollViewer and paginates my stuff!

Is there a proper way of solving this problem?

I also made a screenshot of what this looks like now, but the ScrollViewer scrolls past the end of the document in most cases: http://i.imgur.com/3FSRl.png

<ScrollViewer x:Name="scrollViewer" 
              HorizontalScrollBarVisibility="Visible" 
              VerticalScrollBarVisibility="Disabled"
              >
        <FlowDocumentReader x:Name="flowDocReader" 
                            ClipToBounds="False" 
                            Width="5000"
                            >
            <FlowDocument   x:Name="flowDoc"
                            Foreground="#FF404040" 
                            ColumnRuleWidth="2" 
                            ColumnGap="40" 
                            ColumnRuleBrush="#FF404040" 
                            IsHyphenationEnabled="True" 
                            IsOptimalParagraphEnabled="True" 
                            ColumnWidth="150">

                <Paragraph>
                    Lorem ipsum dolor sit amet, ...etc...
                </Paragraph>
                <Paragraph>
                    Lorem ipsum dolor sit amet, ...etc...
                </Paragraph>
                <Paragraph>
                    Lorem ipsum dolor sit amet, ...etc...
                </Paragraph>
            </FlowDocument>
        </FlowDocumentReader>
</ScrollViewer>
