Remarks

Setting this property provides an alternative to using the ExceptionValidationRule element explicitly. The ExceptionValidationRule is a built-in validation rule that checks for exceptions that are thrown during the update of the source property. If an exception is thrown, the binding engine creates a ValidationError with the exception and adds it to the Validation.Errors collection of the bound element. The lack of an error clears this validation feedback, unless another rule raises a validation issue.

For more information about the validation process for MultiBinding objects, see the ValidationRules property.

ValidatesOnExceptions is introduced in the .NET Framework version 3.5. For more information, see Versions and Dependencies.
