01 <script type="text/javascript">
03 Sys.Application.add_init(initComponents);
05 function initComponents() {
07 }
09 </script>
11 <asp:ScriptManager ID="ScriptManager1"
12 runat="server" />
13 <asp:TextBox runat="server" ID="TextBox1" />
Create and initialize a client behavior named MyCustomBehavior by using the initComponents function. You also need to ensure that
MyCustomBehavior is attached to the TextBox1 Textbox control.
insert at line 06 the following code:

B. $create(MyCustomBehavior, null, null, null, $get('TextBox1'));

74 AJAX Authentication
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:TextBox runat="server" ID="txtUser" Width="200px" />
<asp:TextBox runat="server" ID="txtPassword" Width="200px" />
<asp:Button runat="server" ID="btnLogin" Text="Login" OnClientClick="login(); return false;" />
When a user clicks the btnLogin Button control, the login() client-side script is called to authenticate the user. The credentials provided in the TextBox cont
used to call the client-side script.

.js file:
01 <script type="text/javascript">
02 function login() {
03 var username = $get('txtUser').value;
04 var password = $get('txtPassword').value;
06 // authentication logic.
07 }
08 function onLoginCompleted(validCredentials, userContext,
09 methodName)
10 {
11 // notify user on authentication result.
12 }
14 function onLoginFailed(error, userContext, methodName)
15 {
16 // notify user on authentication exception.
17 }
18 </script>
The ASP.NET application is configured to use Forms Authentication. The ASP.NET AJAX authentication service is activated in the Web.config file.
Ensure that the following workflow is maintained:
On successful authentication, the onLoginCompleted clien-script function is called to notify the user.
On failure of authentication, the onLoginFailed clien-script function is called to display an error message.

Insert at line 06 the following code
A. var auth = Sys.Services.AuthenticationService;
auth.login(username, password, false, null, null,onLoginCompleted, onLoginFailed, null);
