Printing Adorner Layers in a RichTextBox

Question

I have a richTextBox Editor that contains image adorner layers on top of each word.
I want to print the document in a good format and print the adorner picture layers too.
Is there a way I can accomplish this?
I tried PrintDialog but it didnt print the adorner layers.

Answer 1

I managed to print an Adorner layer associated with a item using http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/ae8312df-9ed9-4c4c-951b-42cee5427afa/ . I don't know if it would work for the RichTextBox, I wasn't able to add the Adorner inside the RichTextBox.

Since the Adorner is added OnRender, I had to wait until all was rendered on screen before printing it (hence the Print button), if I printed in the Window_Loaded function, I did not get the Adorner layer.

The Style to the ContentControl is necessary for the AdornerLayer to print.

Code follows:

<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300" Loaded="Window_Loaded">
<Window.Resources>
    <Style TargetType="{x:Type ContentControl}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type ContentControl}">
        <AdornerDecorator>
          <ContentPresenter
                    Content="{TemplateBinding Content}"
                    ContentTemplate="{TemplateBinding ContentTemplate}" />
        </AdornerDecorator>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>
</Window.Resources>
<ContentControl Name="MyContent">
    <StackPanel>
<Grid Name="MyGrid" Margin="10">
    <RichTextBox Name="MyDoc" Margin="2">
        <FlowDocument Name="MyFlow">
            <Paragraph Name="MyParagraph">
                I am a flow document. Would you like to edit me?
                    <Bold>Go ahead.</Bold>
            </Paragraph>

            <Paragraph Foreground="Blue">
                I am blue I am blue I am blue.
            </Paragraph>
        </FlowDocument>
    </RichTextBox>
</Grid>
        <Button Click="Button_Click">Print</Button>
        </StackPanel>
</ContentControl>

Window code

 public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        var myAdornerLayer = AdornerLayer.GetAdornerLayer(MyDoc);
        myAdornerLayer.Add(new SimpleCircleAdorner(MyDoc));


    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        LocalPrintServer ps = new LocalPrintServer();
        PrintQueue pq = ps.DefaultPrintQueue;
        XpsDocumentWriter xpsdw = PrintQueue.CreateXpsDocumentWriter(pq);
        PrintTicket pt = pq.UserPrintTicket;
        if (xpsdw != null)
        {
            pt.PageOrientation = PageOrientation.Portrait;
            PageMediaSize pageMediaSize = new PageMediaSize(this.ActualWidth, this.ActualHeight);
            pt.PageMediaSize = pageMediaSize;

            xpsdw.Write(MyContent);
        }
    }
}

Adorner from Microsoft SimpleCircleAdorner.

Hope this helps you.
