Dear Friends,

am facing problem with session timeout.

I have created a web application in asp.net with C# and database as Sql2005. its works fine.

When the application is idle, it shows the session error.
for this application, first page is login page.

it shows the errror

lbluser.Text = Session["UserName"].ToString();

This code is in master page. this is used for displaying username with label

for example

Welcome Mr. Developer

but when the progam is idle , when i click some links in this application it shows Session Error.

Please help me, how to solve.

Thanks in Advance.

Hi,
What is your timeout setting in config file?

What authentication are you using? ASP.NET Form authentication or you made something on your own?

Please check the session exists or not on pageload

C#

if(Session["UserName"]=="")
{
Response.redirect("Loginpage.aspx");
}

Thanks

Increasing the timeout will in no way fix the problem. It will just cause the issue to appear more infrequently.

HI,

You can check the session existance in the pageload and then perform your operations:

C#

if (!string.IsNullOrEmpty(Convert.ToString(Session["UserName"])))
            {
                //Redirect to the respective page
            }
            else
            {
                //Redirect to the login page
            }

Here IsNullOrEmpty checks for the null as well as "" values simultaneously.

There is another way:

Increase the session timeout value.

1.

Session.Timeout = 540;

OR

2.

C#

<system.web>

.......

<sessionstate timeout="1440"></sessionstate>

</system.web>

Thanks

My 1. Just reposting the existing answers in your own way does not make it a new answer. Still a repost.

Thanks but in the above answers the content and the use are missing. You should be writing the answers in such a way that your code should meet the maximum efficiency. I had added the answers with the proper description inorder to make the enquirer be a good coder. I too hate to repost any answers. But thankd for your concern dear...
