Default Font Size in RichTextBox

[Kate]

Hello! I use RichTextBox with HtmlDataProvider:

<documentsHtml:HtmlDataProvider x:Key="htmlDataProvider"
                           RichTextBox="{Binding ElementName=richTextBox}"
                           Html="{Binding Path=SelectedMessage.NewText, Mode=TwoWay}"
                           SetupDocument="HtmlDataProvider_SetupDocument"/>

When NewText is null or empty RichTextBox shows blank RadDocument and the font size ComboBox shows 12:

<telerik:RadRibbonComboBox CanAutocompleteSelectItems="False" CanKeyboardNavigationSelectItems="False" CommandParameter="{Binding SelectedItem.Tag, RelativeSource={RelativeSource Self}}" Height="21" IsEditable="False" IsReadOnly="True" OpenDropDownOnFocus="True" telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding ChangeFontSizeCommand}" Width="45" DataContext="{Binding ElementName=richTextBox}">

How can I change the default font size to another value?

Hello Kate,

Currently HtmlDataProvider expects to get the font properties from the Source of the binding, specified in the Html property. The default FontFamily in HTML is Times New Roman and the FontSize is 12, hence your ComboBox's 12.
We have considered reviewing this behavior and have decided to include an option for applying the default font properties, defined on RadRichTextBox, onto paragraphs and spans of the document that do not set them explicitly. This change, though, will most probably not appear in the service pack, but in a next release.
If you have any other questions, do not hesitate to contact us again.

Hello Kate,

Another workaround you can try is described in the following thread (especially the discussion with
Michael Montgomery and the sample solution we send to him).
