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

protected:
virtual bool OnServerValidate (
	String^ value
)
protected boolean OnServerValidate (
	String value
)
protected function OnServerValidate (
	value : String
) : boolean
Not applicable.

Parameters

value

The value to validate.

Return Value

true if the value specified by the value parameter passes validation; otherwise, false.

The ServerValidate event is raised when validation is performed on the server.

Raising an event invokes the event handler through a delegate. For more information, see Events and Delegates.

The OnServerValidate method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnServerValidate in a derived class, be sure to call the base class's OnServerValidate method so that registered delegates receive the event.

The following code example demonstrates how to specify and code a handler for a server-side CustomValidator control.

Security noteSecurity Note:

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview (Visual Studio).
