ValidatorCollection Class

Exposes an array of IValidator references. This class cannot be inherited.


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

public sealed class ValidatorCollection : ICollection, 

The ValidatorCollection type exposes the following members.

Public methodValidatorCollectionInitializes a new instance of the ValidatorCollection class.

Public propertyCountGets the number of references in the collection.
Public propertyIsReadOnlyGets a value that indicates whether the ValidatorCollection collection is read-only.
Public propertyIsSynchronizedGets a value that indicates whether the ValidatorCollection collection is synchronized.
Public propertyItemGets the validation server control at the specified index location in the ValidatorCollection collection.
Public propertySyncRootGets an object that can be used to synchronize the ValidatorCollection collection.

Public methodAddAdds the specified validation server control to the ValidatorCollection collection.
Public methodContainsDetermines whether the specified validation server control is contained within the page's ValidatorCollection collection.
Public methodCopyToCopies the validator collection to the specified array, beginning at the specified location.
Public methodEquals(Object)Determines 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 methodGetEnumeratorReturns an IEnumerator instance for the ValidatorCollection collection.
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 methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRemoveRemoves the specified validation server control from the page's ValidatorCollection collection.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast<TResult>Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType<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.

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.

// Get 'Validators' of the page to myCollection.
ValidatorCollection myCollection = Page.Validators;

// Get the Enumerator.
IEnumerator myEnumerator = myCollection.GetEnumerator();
// Print the values in the ValidatorCollection.
string myStr = " ";
while ( myEnumerator.MoveNext() )
   myStr += myEnumerator.Current.ToString();
   myStr += " ";
messageLabel.Text = myStr;
