Session variable values dropping

Question

Hi

I'm new to c# and could use a little guidance.

I'm pulling in a regular text form field from a page in the code behind

    protected void Page_Load(object sender, EventArgs e)
    {
	string GetPassbasket = Request.Form["PassBasket"];
	Response.Write(GetPassbasket);
	Session["PassCart"] = GetPassbasket ;
	Response.Write("<br/>PassCart: " + Session["PassCart"]) ;
    }

which looks like it's setting the session values. However when I move through to the next part it's dropping the string held.

If I give the session a value like

Session["PassCart"] = "My session";

it carries over correctly.

I'd be very grateful if someone could point me in the right direction!!

Cheers

Grant

You should indeed be asking asp.net questions in the appropriate forum.

.

Rather than guess exactly what you're doing here's some markup:

        <div>
         <P>Pass Cart:<asp:TextBox ID="PassCart" runat="server"></asp:TextBox>  </P>
         <P> <INPUT TYPE=SUBMIT>  </P>
         <P> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></P>
        </div>

Code

        protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack)
            {
                Session["PassCart"] = PassCart.Text;
            }
            Label1.Text = Session["PassCart"] as string;
        }

Things in session are objects.

There are two page loads happen, going and coming back.

If that's news then you need to read up on the page lifecycle.

It's complicated, particularly with master pages.

Hope that helps.
