Session not getting created/used

Question

I wrote this code in which I made a session but I am not sure if the session is not getting created or is not getting used

    Session["user"] = this.txtUser.Text.Trim();

The page I am trying to get the session value from :

   protected void Page_Load(object sender, EventArgs e)
   {
    if (Session["user"] == null)
    {
        txtName.Text = Session["user"].ToString();
    }

Answer 1

Change your code from

if (Session["user"] == null)
    {
        txtName.Text = Session["user"].ToString();
    }

to this

if (Session["user"] != null)
    {
        txtName.Text = Session["user"].ToString();
    }

in Page_Load

Because you are setting txtName's Text property when Session is null. It is not the case because session is having previous value of TextBox.

Answer 2

While fetching the session value, the code should be as following,

protected void Page_Load(object sender, EventArgs e)
    {
    if (Session["user"] != null)
    {
        txtName.Text = Session["user"].ToString();
    }
