Strange error message in debug view

[Chintana]

Hi all,

While using the RadTab controller, I found the following error message in debug output window 

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=DropDownButtonElement'. BindingExpression:Path=IsChecked; DataItem=null; target element is 'DropDownMenu' (Name='DropDownMenuElement'); target property is 'IsOpen' (type 'Boolean')

Please try creating a new project and drag and drop the RadTabControl into the main form and execute. In my case, the VS2010 debug output will display the above error

I am using Q1 2010 SP2 of Rad Ctrl set on VS2010 Ultimate.

This does not hamper the performance of the controller, just the error message in the debug view.

Can any one tell me whether I am doing something wrong or whether this is a bug ?

Thanks ,

Chintana

Hello Chintana,

This indeed was a known bug in the TabControl - one of the bindings in its ControlTemplate resulted in this error.

It should not be there any more with the SP release of the controls expected tomorrow.

Yes, this does not affect how the controls works.

Sincerely yours,
