Set background color at runtime?

[Charles Bates]

Hello,
I have seen, in other threads, recommendations for setting the RichTextBox's background color at design-time, in xaml.
Is it possible to change the background at runtime (allowing the user to set the background, for example)?
If not, this would seem like a serious limitation.
Thanks for any information...

Hi Charles Bates,
There are two ways to do this:

1. Change the default background color in the Presenters' default template to Transparent and then change the background of RadRichTextBox:
   

   <telerik:RadRichTextBox Name="radRichTextBox">
       <telerik:RadRichTextBox.Resources>
           <Style TargetType="telerik:DocumentWebLayoutPresenter">
               <Setter Property="Background" Value="Transparent" />
           </Style>
           <Style TargetType="telerik:DocumentPrintLayoutPresenter">
               <Setter Property="Background" Value="Transparent" />
           </Style>
       </telerik:RadRichTextBox.Resources>
   </telerik:RadRichTextBox>

radRichTextBox.Background = new SolidColorBrush(Colors.Yellow);

2. Modify directly the background color of the active presenter like this:

   ((Control)radRichTextBox.ActiveEditorPresenter).Background = new SolidColorBrush(Colors.Yellow);

I hope this solves your problem.

Kind regards,
