How To Redirect To Login Page After Session Timeout

Check out this 7 minute video which shows how to redirect users to a login page when the browser session times out. Click the image to see how to build a small application which uses a Login control, Forms Authentication, and the ASPxHttpHandler module:

Using Forms Authentication in an ASP.NET application makes it difficult to redirect users during callbacks. Since Ajax Callbacks only update partial portions of the page. This makes redirecting kind of a pain.

Imagine you have a page that uses a Grid View with callbacks. If a user’s session times out and the user tries to group, sort, page or any operation that does a callback. Then the browser will idle and display the loading icon spinning as the server tries to redirect to the login page.

There is an easy way to handle this. Just add an ASPxHttpHandler module to your web application and it will redirect a callback when the session has timed out.

Check out the video and then leave me note below about how you plan to use this feature.

Thx, found the answer after watching your video.

Do I have to do this for every page which involves callback?

if(!HttpContext.Current.User.Identiy.IsAuthenticated)

FormsAuthentication.RediectToLoginPage();

appreciated for your quick response,

Kevin

Thx, Mehul.

Since we are on the same page :-), may I ask you on more question:

is there JavaScript Intelligence support for DevExpress controls in VS2008? e.g. type in "ASPxCheckBox." in aspx or js file prompts the list of client side properties and functions

thx

i have a problem with this. if i specify

  <forms name="authForm"

            protection="All"

            timeout="1"              

            path="/"

            loginUrl="login.aspx"

            slidingExpiration="true"

            defaultUrl="FaqeKryesore.aspx"

            requireSSL="false"

            cookieless="UseDeviceProfile"

            enableCrossAppRedirects="false" >      

     </forms>

and

<sessionState mode="InProc" timeout="2"></sessionState> in the web.config,

when the session end after 2 mins fires the Session_end in Global.asax

that destroys the session, and when i go to login.aspx after the authenticate the: FormsAuthentication.RedirectFromLoginPage(this.Login1.UserName, false);

send me to the last request, giving me problems because my session values are null. I tried to make a Response.Redirect instead but that gives me the login.aspx again? how can i work around this?! Thanks in Advance
