RadRichTextBox Print Preview does nothing.

[Cameron Molyneux]

Hi,

I'm using Silverlight RadControls Q2 2010 SP2 (924) and Silverlight 4 plugin.

I have a user control that contains RadRichTexBox and RadRichTextBoxRibbonUI (standard just dropped onto user control) and a RadWindow that justs hosts this user control. The window and editor displays fine however print preview and html print don't appear to work.

When I select the print preview or html print option on the RadRichTextBoxRibbonUI nothing happens at all, I get no errors, I get no print preview window I just get nothing at all. I understand that this is out of the box functionality and should work without adding any code to support the printing? I've added copies of the xaml and code behind files any ideas suggestions?

My User Control Xaml is:

[Iva Toteva]

Hello Cameron Molyneux,

HTML printing and Print Preview are indeed out-of-the box functionalities that we provide. They are supported by the Telerik.Windows.Documents.FormatProviders.Html assembly. Could you please check that there is a reference to this assembly in your Silverlight project, as it may have not been added automatically when you dragged and dropped RadRichTextBoxRibbonUI? Also, please make sure that if you're running your application from inside Visual Studio that you're running the Web project and not the Silverlight one. There is a permission issue otherwise.

If your issues persist, please get back with your browser, browser version and how exactly you're running your application so we can troubleshoot your problem better.

Sincerely yours,
Iva
the Telerik team
