Add a Template column like..

<asp:TemplateField>
    <ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Add Cart" CommandName="ShoppingCart" />
    </ItemTemplate>
</asp:TemplateField>

And then handle the Row command event, where you get:

protected void gdvSearchResults_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "ShoppingCart")
    {
        //AddedControl here in Session Data table 
    }
}
