[Solved] Paragraph spacing - RtfFormatProvider

[Justin Lee]

Hello,

I have a RadRichTextBox that the user can enter formatted text, and save it to the database to view again later.  I use richTextBox1.Document = rtfProvider.Import(formattedText) to populate the textbox, and  rtfProvider.Export(richTextBox1.Document) to get the text to save to the database.  This works just fine.

The problem I'm having is with paragraph line spacing.  Say the user changes the line spacing to single, and the spacing after to 0, then saves the text.  When it's loaded in the textbox again, the line spacing is single (correct), but the spacing after is 9.0 pt (incorrect).

Any ideas?
Thanks,
Justin

<telerik:RadRichTextBox DocumentInheritsDefaultStyleSettings="True"
     Height="140" HorizontalAlignment="Stretch" HorizontalScrollBarVisibility="Hidden"
     IsContextMenuEnabled="True" IsSelectionMiniToolBarEnabled="True"
     IsSpellCheckingEnabled="False" Name="richTextBox1" VerticalAlignment="Top"
     VerticalScrollBarVisibility="Hidden">
</telerik:RadRichTextBox>

// Loading Textbox
String formattedText = //retrieve from database
RtfFormatProvider provider = new RtfFormatProvider();
richTextBox1.Document = provider.Import(formattedText);

// Saving text
RtfFormatProvider provider = new RtfFormatProvider();
string formattedText = provider.Export(richTextBox1.Document);
// save formattedText to database

Some more information...

- I now use databind to the richtextbox -- but I still have the same issue.
- I subscribed to the SetupDocument event, and set e.Document.ParagraphDefaultSpacingAfter = 0 -- but still have the issue
- If I use HtmlDataProvider, I do NOT have the issue.  But I would prefer to use RtfDataProvider.

Thanks,
Justin

void p_SetupDocument(object sender, Telerik.Windows.Documents.FormatProviders.SetupDocumentEventArgs e)
{
  e.Document.ParagraphDefaultSpacingAfter = 0;
}

<my1:RtfDataProvider x:Key="rtfProvider" SetupDocument="p_SetupDocument"

            RichTextBox="{Binding ElementName=radRichTextBox1}"

            Rtf="{Binding Descriptor, Mode=TwoWay}">

</my1:RtfDataProvider>

Hi Justin Lee,
We did not manage to reproduce the issue with a simple document. Could you please send us the problematic document exported as XAML, so we can investigate it further?
ParagraphDefaultSpacingAfter is used on creation of new paragraphs, and SetupDocument event is fired after the document is deserialized, thus the paragraphs' spacing after is not set. You can, however, use RadDocument.EnumerateChildrenOfType<Paragraph>() to get an enumerator of all the paragraphs in the document and  set their SpacingAfter property as needed.
As a general practice, we recommend using our native Xaml format, since with it no information is lost on export/import round-trip.

Don't hesitate to contact us if you have other questions.

All the best,
Boby
