Feature request: Ability to customize scroll bar visibility

[alexrp]

With a RichTextBox, you can change HorizontalScrollBarVisibility/VerticalScrollBarVisibility to customize the scroll bar's visibility. It doesn't appear that there's an equivalent on MarkdownViewer.

The default theme for MardownViewer has a control template with FlowDocumentScrollViewer setting the vertical scrollbar visibility to Auto. You can override it by providing your own template.

Taking by example the MainWindow.xaml from the sample project (some lines omitted for clarity):

<Window x:Class="Markdig.Wpf.SampleApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:markdig="clr-namespace:Markdig.Wpf;assembly=Markdig.Wpf">
  <FrameworkElement.Resources>
    <Style TargetType="markdig:MarkdownViewer">
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="markdig:MarkdownViewer">
            <FlowDocumentScrollViewer Document="{TemplateBinding Document}"
                                      ScrollViewer.HorizontalScrollBarVisibility="Visible"
                                      ScrollViewer.VerticalScrollBarVisibility="Visible" />
          </ControlTemplate>
        </Setter.Value>
      </Setter>
    </Style>
  </FrameworkElement.Resources>
  <DockPanel>
    <markdig:MarkdownViewer x:Name="Viewer"/>
  </DockPanel>
</Window>
