Session variables

[SLG31]

I'm designing like a shopping cart and have a product list which is an xml file consisting of products and prices which is loaded into a dataset then bound to a datagrid

There are buttons next to each product by clicking one of these should direct the user to another form showing the choice of product and price in textboxes, I can't load the info into the next form using session variables

My code is below

1st form code

{code}
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Set the path of XML file and schema
Dim strPath As String = Server.MapPath(".")
' Declare a dataset
Dim dsProducts As New DataSet
' Apply the XML schema to the dataset
dsProducts.ReadXmlSchema(strPath & "\Products.xsd")
' Read the XML into the data set
dsProducts.ReadXml(strPath & "\Products.xml")
DataGrid1.DataSource = dsProducts
DataGrid1.DataBind()
Session("Products") = dsProducts.Tables(0)

End Sub

Private Sub btnJam_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnJam.Click

Response.Redirect("order.aspx")

End Sub
{code}

As you can see I'm trying to create the session variables before the next form is loaded but unsure on the coding for this and for the next form which should load the session variables in the product and price textboxes

Any advice would be appreciated

Thanks
