Problems after downloading 2012_2_0725_Dev_hotfix

[Rob Ainscough]

After downloading 2012_2_0725_Dev_hotfix (note: I did NOT change project references or migrate to the new DLLs) I started getting this error in one of my pages/User Controls ??

Error 26 Ambiguous type reference. A type named 'RadRibbonBackstage' occurs in at least two namespaces, 'Telerik.Windows.Controls' and 'Telerik.Windows.Controls'. Consider adjusting the assembly XmlnsDefinition attributes.

Project references are set to 2012_2_0607 so I don't understand why I'm getting this error?  If I go to the XAML 

<telerik:RadRichTextBoxRibbonUI BackstageClippingElement="{Binding ElementName=gridRadRtbParent}" CollapseThresholdSize="50,50" DataContext="{Binding Path=Commands, ElementName=ManageLettersRadRTB}" Title="Letter" TitleBarVisibility="Collapsed">
                                <telerik:RadRichTextBoxRibbonUI.Backstage>
                                    <telerik:RadRibbonBackstage>

The element <telerik:RadRibbonBackstage> will be identified as the problem with the following highlighted error "Property 'Backstage' does not support values of type 'RadRibbonBackstage'."

So 2 questions:
1.  Why is this now in "two namespaces" of 'Telerik.Windows.Controls'??
2.  Why would just downloading 2012_2_0725 cause this ... or did it?

SOLVED:

It was nothing to do with the latest download.

It was the old refernce "conflict" between Telerik.Windows.Controls.RibbonView and .RibbonBar when using .RichTextBoxUI ... .RibbonView and .RibbonBar don't like each other ;)

There must be a better way for Telerik to deal with this issue moving forward ... wrapper class or something.

Huh, what did you do to solve.  ? 

[Marc Roussel]

I tried to get rid of the RibbonBar reference then I've been able to load the whole RichTextBox editor demo but when running I get full of errors about BackStage

Object of type 'Telerik.Windows.Controls.RadRibbonBackstage' cannot be converted to type 'Telerik.Windows.Controls.RadRibbonBackstage'.

Ouff  I'm not close to have a complete working editor as the demo.....

Hello Marc,

 Could you please check out this help article and let us know if it helps you proceed further? Thank you in advance.

Marc,

You need to remove the project reference to Telerik.Windows.Controls.RibbonBar.

All you need are:
Telerik.Windows.Controls.RibbonView
Telerik.Windows.Controls.RichTextBoxUI

I've opened a ticket for that.  Seems that the problem is more with Visual Studio 2012 RC not totally supported as it is just not working with it but I tried in VS 2010 and it's ok so I assume it's going to be fix in the not so far release for Visual Studio 2012

Thank you anyway
