Inheritance
System.Object
Namespace: Umbraco.Web.Mvc
Assembly: Umbraco.Web.dll
Syntax
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class ValidateUmbracoFormRouteStringAttribute : FilterAttribute
Remarks

Applying this attribute/filter to a SurfaceController or SurfaceController Action will ensure that the Action can only be executed when it is routed to from within Umbraco, typically when rendering a form with BegingUmbracoForm. It will mean that the natural MVC route for this Action will fail with a HttpUmbracoFormRouteStringException.
