Get variable from one method and use as a private string - asp.net

Question

I was really hoping someone could help me,
I need to get the variable product from the method GridView1_RowDataBound to the quote value class string product.
Its for a pdf creator and any help would be greatly appreciated as i've been stuck on this for quite a while, please excuse as I'm fairly inexperienced in .net.
Thanks very much!!
enter code here
public partial class quotedetail : System.Web.UI.Page
{
private string quoteId;
private string product;
private string connectId = "";
string description = "Save Your Quote as a PDF with your Company Logo and Print out for Customers";
public string ConnectId { get { return connectId; } }
protected void Page_Init(object sender, EventArgs e)
{
connectId = Global.GetConnectionString();
quoteId = Request.QueryString["quote"];
product =

Easiest solution would be to put the value in a Session
Session.Add("ProductCode", ((DataRow)((DataRowView)e.Row.DataItem).Row)["ProductCode"].ToString());
To get the value:
Session["ProductCode"].ToString()
Keep in mind though that you are doing this in the item databound, in the event that you are expecting multiple values for product code, I would suggest storing the values in a collection prior to putting it in the Session.
i.e.
if(Session["ProductCode"] != null)
{
List<string> pcodes = Session["ProductCode"] as List<string>();
pcodes.Add(((DataRow)((DataRowView)e.Row.DataItem).Row)["ProductCode"].ToString());
Session.Add("ProductCode", pcodes);
}
else
{
List<string> pcodes = new List<string>();
pcodes.Add(((DataRow)((DataRowView)e.Row.DataItem).Row)["ProductCode"].ToString());
Session.Add("ProductCode", pcodes);
}
To get the values:
Session["ProductCode"] as List<string>()
