Support for Validation Rules in the "Create Data Binding..." dialog.
Please include the ability to add a Validation Rule in the "Create Data Binding..." dialog.
Currently a Validation Rule can only be added to a binding by editing the XAML directly, using element syntax.
To make matters worse the validation rule is deleted if the binding is subsequently modified within Blend.
I want to personally thank you for taking the time to share this suggestion. Since the suggestion you raised has not gathered many votes, the Visual Studio WinTools team is prioritizing other suggestions and closing it at this time.
