Examples

The following code example shows how to use an ASP.NET page that uses a ChangePassword control, and includes a handler for the ChangingPassword event named ChangingPassword. ChangingPassword compares the old password stored in the CurrentPassword property to the new password stored in NewPassword. If they are the same, changing the password fails.

The ChangePassword control sets the DisplayUserName property to true to enable the user to enter their user name. This means that the user does not have to log on to view the page.

The code example assumes that the ASP.NET Web site has been configured to use ASP.NET membership and Forms authentication, and that a user has been created whose name and password are known to you. For more information, see How to: Implement Simple Forms Authentication.

Remarks

The NewPassword property contains the new password entered by the user.

You can use the NewPasswordRegularExpression property to define the requirements for the new password. This regular expression is used to enforce password rules on the client side. The NewPasswordRegularExpression is not related to the password enforcement that can be configured at the data store level. The password must meet the minimum requirements set by the membership provider in the MinRequiredPasswordLength, MinRequiredNonAlphanumericCharacters, and PasswordStrengthRegularExpression properties. If the password does not meet these requirements, the ChangePasswordError event is raised.

Important

Transmitting passwords over HTTP is a potential security threat. HTTP transmissions can be viewed or compromised by malicious users. To improve security when using login controls, you should use HTTPS protocol with secure sockets layer (SSL) encryption to ensure that the user's password cannot be read during postback. For more information, see Securing Login Controls.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
