PasswordRecovery.VerifyingAnswer Event

Occurs when the user has submitted an answer to the password recovery confirmation question.

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

Public Event VerifyingAnswer As LoginCancelEventHandler
<asp:PasswordRecovery OnVerifyingAnswer="LoginCancelEventHandler" />

The VerifyingAnswer event occurs on the server after the user submits the answer to the password confirmation question. You can use this event to prepare the answer submitted by the user for the membership provider, for example by converting it to all uppercase or lowercase letters.

The PasswordRecovery control first raises the VerifyingAnswer event, and then uses the membership provider specified in the MembershipProvider property to compare the answer entered by the user with the password stored in the Web site.

For more information about handling events, see Events and Delegates.

The following code example handles the VerifyingAnswer event and changes the displayed UserName property.

Security noteSecurity Note

This example contains 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.
