first .. this

C#

dr = dt.NewRow();
                dr[1] = Label5.Text;
                dr[2] = TextBox1.Text + TextBox2.Text;
                dr[3] = this.Session["variable2"];

surely would be 'nicer' as

C#

dr = dt.NewRow();
                dr["price"] = Label5.Text;
                dr["quantity"] = TextBox1.Text + TextBox2.Text;
                dr["item"] = this.Session["variable2"];

second .. Im not so sure about this

GridView1.DataBind();

wouldn't that need to be

GridView1.Refresh();

?
