Raises the CustomValidator.ServerValidate event for the System.Web.UI.WebControls.CustomValidator control.
true if the value specified by the value parameter passes validation; otherwise, false.
The CustomValidator.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 CustomValidator.OnServerValidate(string) 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.
