Catastrophic failure

[Titus]

Hello there,

I'm playing with the Demos solution that it's being shipped with the Telerik Silverlight controls, trying to understand how it works.

I don't know whether it's a bug or something else but when I open the file SingleExampleView.XAML in Design mode, I'm getting an exception of type "Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))" in the configurator area, at the line

Path=Content.Content.(telerikQuickStart:QuickStart.ConfigurationPanel)

That exception happens only in Design time, things work well in Run-time.

Could anyone help me out to understand this?
Thanks in advance!

Hi TITUS,

Thanks for your question!

This issue is not related to our demos.
It seems to be a known problem with SL - when binding to a custom attached property an exception is thrown at design time.
It's been reported to Microsoft and you can find some reports here, here and here.

Feel free to contact us, should you have any other questions or problems.

Greetings,

Stanislav
