Session["UserName"]

[John]

Hi,

I use Session["UserName"] to save and pass values between pages, (please see
the following). It works fine on my computer, but on the server, I launch the
main page, wait for 20 minutes, and click a button to launch User.aspx, it
seems that it cannot see the current value of Session["UserName"]. There's no
problem to launch User.aspx from the main page within 20 minutes. Please
help. Thanks.

//Users.aspx
if (!Page.IsPostBack)
{
if (Convert.ToString(Session["UserName"]) != "")
{
//Do something
}
}

Also, the simples way of testing to see if a session variable exists is to
see if it's null or not. Converting it to a string first is a waste. Just do
if(Session["UserName"] != null)
{
Do Something
}

This also helps prevent errors from being thrown if you attempt to convert
upon a null object.

Hope this helps,

And managing the user is really a no-brainer when using ASP.NET 2.0
