The client-side uses callbacks to raise <tt>onServerValidate</tt> event. The <tt>ClientValidationFunction</tt> property is disabled and will throw an exception if trying to set this property. </p> <p> Beware that the <tt>onServerValidate</tt> may be raised when the control to validate on the client side changes value, that is, the server validation may be called many times. After the callback or postback, the {@link onServerValidate onServerValidate} is raised once more. The <tt>IsCallback</tt> property of the <tt>TPage</tt> class will be true when validation is made during a callback request. </p> <com:RunBar PagePath="ActiveControls.Samples.TActiveCustomValidator.Home" /> </com:TContent>
