To whom it may concern:

I'm getting an Exception when opening a xaml file containing the <telerikNavagation:treeview> in Expression Blend 3.  The version of the controll that I'm using is "2009.3.1103.1030".

I'm using Visual Studion 2008 sp1.

Basically, what I did was drag and drop the controll from the toolbar to my silvierlight xaml file and attempted to open the file in Expression Blend 3.  I get the following error:

Exception: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED))

StackTrace
at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
at MS.Internal.XcpImports.Collection_InsertValue[T](PresentationFrameworkCollection~1 collection, UInt32 index, CValue value)
at MS.Internal.XcpImports.Collection_InsertDependencyObject[T](PresentationFrameworkCollection`1 collection, UInt32 index, DependencyObject value)
at System.Windows.PresentationFrameworkCollection`1InsertDependencyObject(int32 index, DependencyObject Value)
at System.Windows.Controls.UIElementCollection.InsertInternal(Int32 index, UIElement value)
at System.Windows.PresentationFrameworkCollection~1.Insert(Int32 index, T value)

InnerException:None

Any help is very much appreciated.
Thanks,
Kong

Hi Kong Ung,

I would advice you to check the following things:
1.Check if you have added all the necessary references:
Telerik.Windows.Controls.dll
Telerik.Windows.Controls.Navigation.dll
etc.
2.Try to restart Blend

There a many reasons why an application would crash with Catastrophic failure... maybe it is a custom style that is no longer valid.We were unable to reproduce this issue so may I ask you for more information about your application and the version of  the OS? We would really appreciate it if you could send us a project that will help us to reproduce the problem.

Kind regards,

Boryana,

I have found the solution to the problem.  I reset the toolbox and re-add the silverlight controls.  I believe I did not reset the toolbox during the upgrade to 3rd quarter release.

I'm sorry for any inconvenience this may have caused you.

Thanks again for your time.

Sincerely,
Kong
