Pass grid-view Values even if column is not visible

Question

hello i am trying to pass values from gridview to another form but my problem is that when i make the coloumn visible=false, data of this column is to showing up so any help how can i get value of coloumn even if the coloumn is unvisible..

 

my grid view data : 

 

<ItemTemplate>
<asp:Button ID="Button1" Text="Edit" runat="server" BorderStyle="None" OnClick="Send" ForeColor="CornflowerBlue" CssClass="button1" OnClientClick = "SetTarget();" Width="50px"/>
</ItemTemplate>
</asp:TemplateField>

and on page load of this page :

 

protected void Page_Load(object sender, EventArgs e)
  {
      Label1.Visible = false;


       if (!IsPostBack)
          BindGrid();

       GridView1.Columns[0].Visible = false;
       GridView1.Columns[1].Visible = false;
  }

and the send edit button here i tried to show the coloumn and send the data with the button but it didnt work:

protected void Send(object sender, EventArgs e)
   {

       //Reference the Button.
       Button btnSend = sender as Button;

       //Reference the GridView Row.

       GridViewRow row = btnSend.NamingContainer as GridViewRow;


       //Save the GridView Row in Session.
       GridView1.Columns[1].Visible = true;
       Session["Row"] = row;

       //Redirect to other Page.
       Response.Redirect("EditAddPack.aspx");
   }

finally my another page load iam getting the data like this with all the columns that are only visible = true;

if (Session["Row"] != null)
                   {
                       //Fetch the GridView Row from Session.
                       GridViewRow row = Session["Row"] as GridViewRow;

                       //Fetch and display the Cell values.

                       editstdidlbl.Text = row.Cells[1].Text; // here iam not getting this lable since i put it unvisible in the gridview
                       editCoachdroplist.SelectedValue = row.Cells[2].Text;
                       editSTDDropDownList.SelectedItem.Text = row.Cells[3].Text;
