ServerValidateEventHandler Delegate

Represents the method that will handle the ServerValidate event of a CustomValidator control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public delegate void ServerValidateEventHandler (
	Object^ source, 
	ServerValidateEventArgs^ args
/** @delegate */
public delegate void ServerValidateEventHandler (
	Object source, 
	ServerValidateEventArgs args
JScript supports the use of delegates, but not the declaration of new ones.



The source of the event.


A ServerValidateEventArgs that contains the event data.

Use this delegate to provide custom code that performs validation on the server. Your code needs to validate the Value property of the args parameter passed to the delegate. Store the result of the validation in the IsValid property of the args parameter.

When you create a ServerValidateEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.

For more information about handling events, see Consuming Events.

The following example demonstrates how to specify and code a handler for a server-side CustomValidator. It displays whether a number entered into a text box is odd or even.
