CustomValidator::OnServerValidate Method
Raises the ServerValidate event for the CustomValidator control.
Assembly: System.Web (in System.Web.dll)
Parameters
- value
- Type: System::String
The value to validate.
Return Value
Type: System::Booleantrue 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.
