AssociatedValidatorProvider Class

Visual Studio 2010

Provides an abstract class for classes that implement a validation provider.

Namespace:  System.Web.Mvc
Assembly:  System.Web.Mvc (in System.Web.Mvc.dll)

public abstract class AssociatedValidatorProvider : ModelValidatorProvider

The AssociatedValidatorProvider type exposes the following members.

Protected methodAssociatedValidatorProviderCalled from constructors in derived classes to initialize the AssociatedMetadataProvider class.

Public methodEqualsDetermines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodGetTypeDescriptorGets a type descriptor for the specified type.
Public methodGetValidators(ModelMetadata, ControllerContext)Gets the validators for the model using the metadata and controller context. (Overrides ModelValidatorProvider.GetValidators(ModelMetadata, ControllerContext).)
Protected methodGetValidators(ModelMetadata, ControllerContext, IEnumerable<Attribute>)Gets the validators for the model using the metadata, the controller context, and a list of attributes.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

A validation provider provides validation logic for the data model. A validation provider must derive from ModelValidatorProvider. You can inherit from this class if you want to use a custom validator provider or a third-party validator that uses attribute-based metadata. This class performs most of the work that is required in order to implement the ModelValidatorProvider class.

When you implement this class, use the AssociatedMetadataProvider class to implement the metadata provider.

Model provider classes and validator provider classes are loosely coupled. Therefore, they work independently, and have no dependencies on each other.

However, the metadata provider exposes metadata that can be accessed and used by validation providers. For example, the MVC default metadata provider (the DataAnnotationsModelMetadataProvider class) reads the display name of an object, and the display name is used by the DataAnnotationsModelValidatorProvider validation provider when it creates a validation error message.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
