Default Line Spacing

[tj]

Hi,

When I create the richtextbox editor, the default line spacing is single. But when I bind it to my viewmodel, the default line spacing is set to multiple. Can I set the default line space to just single?

thanks,
tj

Hello tj,

When binding RadRichTextBox through a format provider, the format provider actually instantiates a new RadDocument and sets the Document property of the RadRichTextBox to the newly created document. Therefore, your custom settings do not apply.
What you can do is catch the SetupDocument event of the provider, which occurs after setting the content of the document but before visualizing it on the page, and handle it as you like. Some help on this is available here.
In your case, you would need something like:

private void HtmlDataProvider_SetupDocument(object sender, Telerik.Windows.Documents.FormatProviders.SetupDocumentEventArgs e)
        {
            e.Document.LineSpacing = 1.15;
        }

Hi,

The link you posted gives an error.

I am binding a RadRichTextBox to Txt:TxtDataProvider and want to set the default Paragraph SpacingAfter to 0. I already tried doing this:

<Txt:TxtDataProvider   RichTextBox="{Binding ElementName=description}"
                                    Text="{Binding Description, Mode=TwoWay}" />
<telerik:RadRichTextBox  x:Name="description" DocumentInheritsDefaultStyleSettings="True" >
                <telerik:RadRichTextBox.Document>
                    <telerik:RadDocument>
                        <telerik:Section>
                            <telerik:Paragraph SpacingAfter="0" />
                        </telerik:Section>
                    </telerik:RadDocument>
                </telerik:RadRichTextBox.Document>
            </telerik:RadRichTextBox>

But from what you wrote, it won't work. Any other links?

Thanks,

Jonathon

Hi Jonathon,

I am sorry, this is the correct link: http://www.telerik.com/help/silverlight/radrichtextbox-features-data-providers.html.
Here is also a code-snippet, which should be what you need:

<Txt:TxtDataProvider RichTextBox="{Binding ElementName=description}"
               Text="{Binding Description, Mode=TwoWay}"
               SetupDocument="TxtDataProvider_SetupDocument" />

And the same code from my previous post in the handler for the SetupDocument event:

private void TxtDataProvider_SetupDocument(object sender, Telerik.Windows.Documents.FormatProviders.SetupDocumentEventArgs e)
        {
            e.Document.LineSpacing = 1;
        }

Thanks, that's exactly what I needed.
