Get value from BoundField in ASP.NET

Question

I have two BoundFields one of them is pure text and the other is a numeric value.

Here's a sample of one of them:

<asp:DetailsView ID="detailsview2" runat="server" 
                 Height="40px" Width="342px" AutoGenerateRows="false" 
                 DataSourceID="sqldatasource1" 
                 BorderStyle="None" GridLines="None">
    <AlternatingRowStyle BorderStyle="None" />
    <CommandRowStyle BorderStyle="None" />
    <EditRowStyle BorderStyle="None" />
    <EmptyDataRowStyle BorderStyle="None" CssClass="tdInexistente" />
    <FieldHeaderStyle BorderStyle="None" />
    <Fields>
        <asp:BoundField DataField="nome_produto" SortExpression="nome_produto" />
    </Fields>
    <FooterStyle BorderStyle="None" />
    <HeaderStyle BorderStyle="None" />
    <InsertRowStyle BorderStyle="None" />
    <PagerStyle BorderStyle="None" />
    <RowStyle BorderStyle="None" />
</asp:DetailsView>

I need to put the BoundFields values inside some Sessions so I can use them on another page.
