Introducing the Login Controls x 617
10. Save all your changes and request Login.aspx in your browser. Log in
with the account and password you created in a previous exercise (you
may need to log out first by clicking the Logout link). If you don’t recall
the username and password, simply click the Sign Up link to create a new FIGURE 16-10
account. Note that as soon as you are logged in, the footer displays the text visible in Figure 16-10.
11. Click the Login item in the Menu or TreeView to go to the Login page. Instead of the Login control
you should now see a message indicating that you are already logged in.
12. Click the Logout link in the footer at the bottom of the page. The page refreshes and displays the
Login control again. Additionally, the text from the footer has now disappeared.
How It Works
You started by adding a LoginView to the Login page to wrap the Login control and a text message.
The Login control is shown when the user is not logged in, whereas the text is displayed for logged-in
users only.
The code in the footer of the master page contains a LoginName control that displays the name of the
user that is logged in. It doesn’t display anything for anonymous users. To control the text being displayed,
you use the FormatString property:
At run time, the {0} is replaced with the user’s name.
By default, the LoginStatus you added displays a link to enable users to log in and log out. Because
the Menu or the TreeView already contains a link to the Login page, the footer uses a LoginView again
to display the Logout text only when the user is currently logged in. If you want to add a Login link as
well, you can extend the LoginView with an anonymous template and an additional LoginStatus or
remove the entire LoginView so the LoginStatus is visible to all users.
In addition to the controls you have seen that enable a user to log in and that use the current user’s
log-in status to show or hide relevant content, the Login category of the Toolbox contains three
more controls that enable users to sign up for a new account on the site, to change an existing password,
and to recover a lost password. These controls are discussed next.
CreateUserWizard
You briefly saw CreateUserWizard at work in an earlier exercise. But the control has a lot more to
offer than the standard behavior you saw in that exercise.
To start with, the control has a long list of Text properties, such as CancelButtonText,
CompleteSuccessText, UserNameLabelText, and CreateUserButtonText, that affect the text
used in the control. All properties have good (English) defaults, but you can change them if they
don’t suit your needs.
