Gets or sets a value that indicates whether the binding engine will report exception validation errors.
Assembly: System.Windows (in System.Windows.dll)
Setting to true tells the binding engine to catch exceptions that occur when updating the source object from the target in TwoWay bindings. The exceptions can occur in two ways:
1. Thrown from the source object's setter function.
2. Thrown by the type converter.
In order to receive notification that these exceptions have occurred, you must set the NotifyOnValidationError property to be true.
If this property is set to false, the application will silently fail on validation exceptions.
