问题 In my WPF application I've a ListBox binding to a collection of view models. Those view models support validation by implement INotifyDataErrorInfo. I’m trying to display an error template for items with validation errors in my ListBox.

Does any similar validation styles/templates exist in the WPF Framework or has anybody created nicely styled validation templates like the Silverlight version above? Or will I have to create them from scratch? If anybody
