Error when running application (2011.1.419.35)

[Robert]

Good evening,

I get the following error for the RadRichTextBox when trying to run my application.

Missing Method Exception:
Method not found: '!!0 Telerik.Windows.Controls.DependencyObjectExtensions.GetVisualParent(System.Windows.DependencyObject)'.

I'm not really sure what's going on. I use all of the references that are mentioned in the documentation.
The error is thrown when I click on the RichTextBox and try to type characters into it.

Any help is greatly appreciated. I'm using version 2011.1.419.35.

Thank you very much.

Hello Robert,

I tried a simple demo with RadRichTextBox from the controls version you have specified and was not able to reproduce the problem.
Could you check if the versions of all Telerik assemblies you are using is the same, as I have verified that the DependencyObjectExtensions.GetVisualParent(System.Windows.DependencyObject) method is included in the 2011.1.419 version of Telerik.Windows.Controls.
If the problem persists, we would appreciate it if you could open a support ticket and attach a demo in which the problem can be reproduced. You can find attached the demo I used for testing.

Kind regards,
Iva
the Telerik team
