WPF window fails to load properly in designer

[Alan Cordner]

I have been developing an application in WPF using the RadControls for WPF trial version (2009 Q3 I think) over the last few months. Just last week I was able to purchase the RadControls suite and installed them on my machine. Everything has been working fine, even as early as this morning, until this afternoon. For some unexplained reason, my main window no longer appears at design time. By trial and error, I have narrowed the problem down to the inclusion of the references to Telerik.Windows.Controls, Telerik.Windows.Controls.Navigation, and Telerik.Windows.Data. Removing these references and code that requires them resolves the issue.

To test this, I created a new project (WPF application) in VS2008. The application built and ran without me making any modifications to it. Then, I added the references listed above and attempted to run it again. The application runs, but at design time the main window Window1.xaml is not displayed. Instead, I get the following exception information:

Exception has been thrown by the target of an invocation.

Again, I did NOTHING to this project except add the references to it. Removing the references causes the exception to disappear and the window is displayed at design time as expected.

This exception is a little different from the exception I get in my other application, which contains two nested RadTabControls. Here is that exception:

            InnerException:

This application will only display the main window at design time if I remove the references I mentioned above. Even removing all of the RadTabControl XAML code does not allow the window to be displayed if the references are still included.

The only odd thing I remember seeing immediately before this started happening was a green balloon appearing on the Telerik menu in VS2008 indicating there was an upgrade available and asking if I wanted to upgrade my project. I ignored the message because I did not want to affect my project until I reached a point where I could deal with that by itself. After this exception started to occur, I tried running the upgrade to see if that would resolve the problem, but it did not. I also uninstalled ALL Telerik WPF controls from my machine and re-installed the 2010_0309_DEV version. (JustCode is also installed on my machine)

Here is my XAML code for the window that will not load in the designer:

One other thing to note is that my application DOES actually run, but the orientation and alignment of the nested tab control's tab headers (defined by the productsHeaders template) has changed seemingly on its own since the last time the application worked without raising this exception. The nested tab header content is rotated 90 degrees clockwise and the tabs themselves are vertically bottom aligned instead of top aligned. The ScrollMode is also being ignored (using Pixel instead of Item).

I've got this same error since upgrading to the March 9th 2010 assemblies on a test app Im messing about with to trial the telerik components,

I have a main user control which has a Ribbon and a Docking manager on it and the error throws in InitialiseComponent(). The xaml for this control is posted below. There's not a lot going on here, just a ribbon with one tab (Home) with nothing on it, three docking panes.

The exception message is 

Cannot convert string 'telerik:VistaTheme' in attribute 'ThemeType' to object of type 'System.Type'. Could not load file or assembly 'Telerik.Windows.Data, Version=2010.1.309.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

Note, if I cut the Ribbon Bar definition in xaml down to this, it still fails, but now with the following exception message:

Could not load file or assembly 'Telerik.Windows.Controls.RibbonBar, Version=2010.1.309.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference

<telerikRibbonBar:RadRibbonBar Grid.Row="0" >
        </telerikRibbonBar:RadRibbonBar>

When I downloaded the March 2010 release I took the DLLs only and referenced them from my project (I have a local project directory called "Dependencies" with all the Dlls in). I am currently uninstalling the entire Q3 2009 package (to reinstall with Q1 2010) to see if that helps.

[Andrew Thompson]

Ok I fixed this error on my machine, here's the steps I took - hope it helps you too! 

(Dont know which step precisely fixed it, but I believe the issue was due to there being multiple Telerik assembly versions on the machine and the .NET runtime trying to load Q1 2010 and Q3 2009 for the ribbon bar)

• Close all instances of Visual Studio
• Completely uninstalled Telerik Q3 2009 from control panel
• Searched for any DLL named Telerik on my computer and deleted
• Downloaded/copied Telerik March 2010 Assemblies into Dependencies folder in my code directory
• Opened the code folder and searched/deleted all bin/obj directories
• Open Visual Studio, removed and re-added all Telerik DLLs as references
• Set all Telerik DLLs to “Copy Local – True” on the Main exe, set all Telerik DLLs to copy local - False on satellite DLLs
• Clean/Rebuild again – magically worked!

Sorry - yes, the updated libraries resolved the design time problems, even though I am not running Windows 7 nor a 64-bit environment (Vista 32-bit).

Thank you for being so responsive!

There is always someone at the end of a thread who posts when the problem has been fixed for everyone! Sadly this person is myself.
I'm receiving this error when trying to compile a WPF application. I've tried each step outlined in Andrew Thompson's post and also extracted and installed the design assemblies. So am a little lost for ideas on how to fix this. Any help greatly appreciated:

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

Additional information: '/Telerik.Windows.Controls.Navigation;component/themes/vista/CarouselDataFieldPresenter.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Object reference not set to an instance of an object.  Error at object 'System.Windows.ResourceDictionary' in markup file 'Telerik.Windows.Controls.Navigation;component/Themes/GenericVista.xaml'.

I had the same problem on VS2008 Win7/64 when installed 10q1 instead 09q3. Even demo application coulnd't run properly reporting this error. Alan referenced the forum thread with the fix which fixed the problem. Before I tried to rename libraries according another method to xxx4.0 but it didn't help and I revesed it back.
Mark, but if your application can't compile - try to remove all Debug folders with all telerik libs(dlls) and recompile it again. Probably it catch them somehow.
