Constructors

Name Description
ValidationVisitor(ActionContext, IModelValidatorProvider, ValidatorCache, IModelMetadataProvider, ValidationStateDictionary)

Creates a new ValidationVisitor.
ValidationVisitor(ActionContext, IModelValidatorProvider, ValidatorCache, IModelMetadataProvider, ValidationStateDictionary)

Creates a new ValidationVisitor.

Properties

Name Description
AllowShortCircuitingValidationWhenNoValidatorsArePresent
Obsolete.

Gets or sets a value that determines if ValidationVisitor can short circuit validation when a model does not have any associated validators.
Cache

The validator cache.
Container

The container.
Context

The action context.
CurrentPath
Key

The key.
MaxValidationDepth

Gets or sets the maximum depth to constrain the validation visitor when validating.

ValidationVisitor traverses the object graph of the model being validated. For models that are very deep or are infinitely recursive, validation may result in stack overflow.

When not null, Visit(ModelMetadata, String, Object) will throw if current traversal depth exceeds the specified value.

Metadata

The model metadata.
MetadataProvider

The model metadata provider.
Model

The model.
ModelState

The model state.
Strategy

The validation strategy.
ValidateComplexTypesIfChildValidationFails

Indicates whether validation of a complex type should be performed if validation fails for any of its children. The default behavior is false.
ValidationState

The validation state.
ValidatorProvider

The model validator provider.

Methods

Name Description
GetValidationEntry(Object)

Get the validation entry for the model.
SuppressValidation(String)

Supress validation for a given key.
Validate(ModelMetadata, String, Object, Boolean, Object)

Validates a object.
Validate(ModelMetadata, String, Object, Boolean)

Validates a object.
Validate(ModelMetadata, String, Object)

Validates a object.
ValidateNode()

Validates a single node in a model object graph.
Visit(ModelMetadata, String, Object)

Validate something in a model.
VisitChildren(IValidationStrategy)

Validate all the child nodes using the specified strategy.
VisitComplexType(IValidationStrategy)
