Syntax

C++

public ref class ValidatorCollection sealed : ICollection, IEnumerable

Constructors

	Name	Description
	ValidatorCollection()	Initializes a new instance of the ValidatorCollection class.

Properties

	Name	Description
	Count	Gets the number of references in the collection.
	IsReadOnly	Gets a value that indicates whether the ValidatorCollection collection is read-only.
	IsSynchronized	Gets a value that indicates whether the ValidatorCollection collection is synchronized.
	Item[Int32]	Gets the validation server control at the specified index location in the ValidatorCollection collection.
	SyncRoot	Gets an object that can be used to synchronize the ValidatorCollection collection.

Methods

	Name	Description
	Add(IValidator^)	Adds the specified validation server control to the ValidatorCollection collection.
	Contains(IValidator^)	Determines whether the specified validation server control is contained within the page's ValidatorCollection collection.
	CopyTo(Array^, Int32)	Copies the validator collection to the specified array, beginning at the specified location.
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetEnumerator()	Returns an IEnumerator instance for the ValidatorCollection collection.
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	Remove(IValidator^)	Removes the specified validation server control from the page's ValidatorCollection collection.
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Extension Methods

	Name	Description
	AsParallel()	Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)
	AsQueryable()	Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)
	Cast<TResult>()	Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)
	OfType<TResult>()	Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

Each ValidatorCollection reference is associated with a validation server control contained on the requested page. These controls add themselves to this collection when the Init event of the Page object is handled. They remove themselves when the Unload event of the Page object is handled. The Page class inherits both of these methods from the Control class.

You can access this collection, its methods, and its properties through the Page::Validators property. If the tested condition of any validator in this collection fails, the Page::IsValid property is set to false.

Examples

The following code example demonstrates how to access the collection through the Page::Validators property and use the GetEnumerator method to iterate through the values.
