Show xaml

[Edo Cof]

I am trying to use RichEdit for commenting something.
So the user enter some text, i save it to the base as xaml string (link), but then i want to show it in xaml, and that's the problem.

I write:

            string text = "<t:RadDocument xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:t=\"clr-namespace:Telerik.Windows.Documents.Model;assembly=Telerik.Windows.Documents\" ParagraphDefaultSpacingBefore=\"0\" SectionDefaultPageMargin=\"10,10,10,10\" PageViewMargin=\"10,10\" LayoutMode=\"Flow\"><t:Section PageMargin=\"10,10,10,10\"><t:Paragraph SpacingAfter=\"12\"><t:Span Text=\"This is a test.\" FontFamily=\"Verdana\" /></t:Paragraph></t:Section></t:RadDocument>";

            RadRichTextBox rich = new RadRichTextBox();
            rich.Document = XamlReader.Load(text) as <RadDocument>();
            xamlPlaceHolder.Child = rich;

But the user can edit text. I know that i can set read only to true, but the user can still focus RadRichTextBox.

I just want to show text that user enter it when commenting. (with formating of course)

Hi Edo Cof,

Setting the IsReadOnly property to true will prevent user from modifying the content of the RadRichTextBox. However, the control will still receive focus and will allow the user to select and copy parts of its content.

If you want to stop the control from ever receiving focus, you can try setting the IsEnabled property to false.  

Please let us know if this is what you need or if you need further assistance.

IsEnabled is a very nice idea. Don't know how i missed it. I will try it and probably it will work.
If user can select text is very good, if not it will be nice to find work arround or add this feature.
(I already post for feature request RichEditViewer)

Now the second thing that bothers me is white background.
I want to show text as plain text (as html) just if i write a textblock.
If i say the other way, how can i remove that white background, so the text background (RadDocument) will be transparent?

Hi Edo Cof,

You can remove the white page background by overriding the default Page template used by the RadRichTextBox. If you want the control to be fully transparent you will have to set the Background property of the RadRichTextBox to Transparent too. Here is an example:

<telerik:RadRichTextBox x:Name="editor" Background="Transparent">
  <telerik:RadRichTextBox.Resources>
    <Style TargetType="docUI:Page">
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="docUI:Page">
            <ContentPresenter x:Name="PageContentPresenter"
                                      Visibility="Collapsed"/>
          </ControlTemplate>
        </Setter.Value>
      </Setter>
      <Setter Property="HorizontalAlignment" Value="Center" />
      <Setter Property="VerticalAlignment" Value="Top" />
    </Style>
  </telerik:RadRichTextBox.Resources>
</telerik:RadRichTextBox>

You will have to add and the following xml namespaces:

xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Documents"
xmlns:docUI="clr-namespace:Telerik.Windows.Documents.UI;assembly=Telerik.Windows.Documents"

Let us know if this was helpful.

Kind regards,

It seems it works, but i am having problems adding this resources into control template. (So i don't need to add this code every time i want to use that kind of behaviour.

Is this possible?

Hi Edo Cof,

If you want to use this style resource throughout your entire application, you can put it in the App.xaml file. This way you will not need to add it every time you use the RadRichTextBox control.

All the best,
