In order to change their password, users must be authenticated by the membership provider. To allow users who are not logged on to change their password, or to be authenticated by the membership provider with a different user account and then change the password for that account, the ChangePassword control can display a TextBox control to accept the user name.
You must set the property to true if the ChangePassword control will be displayed to users who are not logged on; otherwise, the user will not be able to specify a user name.
The following code example shows how to set the property to display the UserName control to users who are not logged on to the Web site.
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. The code in the ChangingPassword handler compares the old password stored in the CurrentPassword property to the new password stored in NewPassword. If the two passwords are the same, changing the password fails.
The ChangePassword control sets the 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.
