Hello Jon,

When you bind the Content of RadTransitionControl to a SelectedItem of ItemsControl, this means that RadTransitionControl will try to place the SelectedItem in its Context and this item will have two references to two different controls, which is not supported in Silverlight framework.

Please do not hesitate to contact us if you require any further information.

Kind regards,

Hi..
I'm trying to do this in WPF...
any ideas?
thanks

[George]

Hello Jon,

This is not supported in WPF, neither. It's framework limitation, too.
I would suggest you to get the selected item using Selected event handler of RadPanelBar control. Then, you could clone the selected RadPanelBarItem using XamlWriter and pass the cloned object to the Context of the transition control.

I hope this helps! Please do not hesitate to contact us if you require any further information.

Hi..
I don't understand...
How can you use the Transition Control with the Tab or Panel ?
thanks again

[George]

Hi Jon,

Attached you can find a sample that illustrates the use of XamlWriter. I hope this helps.

As long I am not quite sure that I understand what you want to achieve, I will ask you for your feedback. Let me know if this sample suits your needs. If it doesn't, please, describe your scenario in details.

I will be glad to assist you further.

Kind regards,

Thanks..
What I'm try to do is - have some cool effects when the current tab comes into view or when you switch panels or tabs.
thanks

When you click on a 'new' tab - tab changes or a diff panel is selected...

 have some cool effects when the current tab comes into view or when you switch panels or tabs.
