session declaration

i want to store a dataset value in a session variable but keep getting the value returned as false when i try and write it to the page, when i write the dataset value to the page it works fine but trying to store in the session is the problem, i have pasted the code below, i use classic asp more so this is where i am probably going wrong, i know there are 3 different types of session in .net but not sure how write them correctly.

<p><%# Session("finalu") =  DataSet1.FieldValue("UserID", Container) %></p>
<p><%= session("fianlu")%></p>

well what language are you using...if it's vb, i think you have to use the Session.Add

if it's c# i think you can just use Session["fadfsd"] =
here code in C#

to store dataset in session  variable and read from session variable to attach into gridview.

Make sure you use this.DataBind() to bind dataset to gridview control
    protected void Button1_Click(object sender, EventArgs e)
        DataSet ds = ProductsDataAccess.GetProductByCategory(1);
        Session["MyDataSet"] = ds;
    protected void Button2_Click(object sender, EventArgs e)
        DataSet ds = (DataSet)Session["MyDataSet"];
        GridView1.DataSource = ds.Tables["Products"];

Logic would be same only the syntax would be difference...

//set to session variable
Session("varname") = value

//read from session varible

        Dim ds As DataSet = ProductDataAccess.getProductsbyCategoryID(1)
        Session("MyDataSet") = ds
    End Sub
    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim ds As DataSet = Session("MyDataSet")
        GridView1.DataSource = ds.Tables("Products")

hi vbsquickresponse:

thanks for the code,

couldn't get that working, surely there must be a way of assigning a value to a session by using a simple statement lke <p><%# Session("finalu") =  DataSet1.FieldValue("UserID", Container) %></p>
i can get the value for the session from a Request.QueryString("Username") either from the current page.

i am using a post method on this page so have struggled to access the Request.QueryString("Username") from my next page that is why i am trying to put it in a session variable so i can access it on the next page.
