PasswordRecovery.OnAnswerLookupError Method

Note: This method is new in the .NET Framework version 2.0.

Raises the AnswerLookupError event.

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

protected virtual void OnAnswerLookupError (
	EventArgs e
protected void OnAnswerLookupError (
	EventArgs e
protected function OnAnswerLookupError (
	e : EventArgs



An EventArgs that contains the event data.

The OnAnswerLookupError method is called when the user's answer to the password recovery confirmation question does not match the answer stored in the Web site data store. The default implementation raises the AnswerLookupError event.

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

The OnAnswerLookupError 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 OnAnswerLookupError in a derived class, be sure to call the base class's OnAnswerLookupError method so that registered delegates receive the event.

The following code example creates a custom PasswordRecovery control that overrides the OnAnswerLookupError method to change the QuestionTitleText property if the user enters an incorrect answer to the password confirmation question.

<%@ page language="C#" %>

<script runat="server">
    class CustomPasswordRecovery : PasswordRecovery
        override protected void OnAnswerLookupError(EventArgs e)
            QuestionTitleText = "Try again";
            TitleTextStyle.ForeColor = System.Drawing.Color.Red;
        // Add the custom password recovery control to the page.
        void Page_Init(object sender, EventArgs e)
            CustomPasswordRecovery passwordRecoveryControl = new CustomPasswordRecovery();
            passwordRecoveryControl.ID = "passwordRecoveryControl";

<form runat="server">
        <asp:placeholder id="PlaceHolder1" runat="server"></asp:placeholder>&nbsp;</p>
