I am having a strange problem. I set up the RadPanelBar to automatically scroll through the items in the list, and expand each selected item. When the user clicks on an item, it stops auto scrolling and should act as normal. The auto scroll works perfectly. However, when the user clicks to stop the auto scroll, if an item is clicked that is only *partially* showing in the scroll view area AND *above* the currently selected item, the item will not expand. If the item is below the currenly selected item, it's fine. If the item is in full view in the scroll view area, it's fine. How can I resolve this??

I attached the xaml and code behind files. Any help is hugely appreciated!! Let me know if you need anything else from me.

I noticed that the item container is null in the item click event. Any idea why? If that could be filled, I think I can solve my issue.

Hello Jessica,

Thank you for your detailed information. However, we will need more time to look into your scenario and the custom logic you implemented for the auto scroll feature and look for what might be causing this behavior.

I will get back to you as soon as we have more info.

All the best,

Hello Jessica,

First of all I'd like to apologize for the delayed response. I examined the code sample you sent and I noticed a few things.

Firstly, by default when you click on a PanelBarItem it is automatically expanded and this is why you don't have to implement any custom logic controlling the expanding of a clicked item

Also, I am not sure why you need to handle the SelectionChanged event as you have the ChangeSelectedItem() method where you can place all logic related to the selected item. Moreover, the RadPanelBar control expose a SelectedContainer property which you can use to get the selected RadPanelBarItem container out-of-the-box.

Basically the SelectionChanged event is fired for each item, which IsSelected property is changed and this is why your custom logic will be executed too many times thus causing the issues you described.

I modified slightly your code to implement the above suggestions and I used it to create the attached sample. Can you please give it a try and let me know if it works for you.

All the best,
