ValidationErrorEventAction Enumeration

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Describes the reason a BindingValidationError event has occurred.

Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)

Syntax

No code example is currently available or this language may not be supported.

Members

	Member name	Description
	Added	A new ValidationError has occurred.
	Removed	An existing ValidationError has been removed.

Remarks

If a validation error occurs, the binding engine raises the BindingValidationError event. A ValidationError passes to the event handler containing a new Exception and the Action value is Added. If the validation error is resolved, most likely by the user updating the entry with valid information, then the same ValidationError passes to the event handler with the original exception and the Action value is Removed.
