“BindingExpression path error” using ItemsControl and VirtualizingStackPanel

Question

I\'m using Silverlight on Windows Phone 7.

Is it normal to get loads of \"BindingExpression path error\" debug messages when using a VirtualizingStackPanel? I think it

Answer 1

I think your assessment of the situation is correct, but it sounds like a bug in the way the VirtualizingStackPanel works. It's not affecting the execution or bindings of your application at the points where you need it, but raising exceptions is a relatively expensive operation and so it would make sense to update the appropriate DataContext accordingly when unlinking the containers.

I think the best place to raise it as a potential bug would be on the App Hub forums
