I have a session gridview and a session datatable. I want to display the session gridview on pageload itself. No error or exception is thrown. But I am unable to see the gridview.
Here is my code:

VB

<asp:GridView ID="grv" runat="server"
               ShowFooter="True" AutoGenerateColumns="False"
               CellPadding="4" ForeColor="#333333"
               GridLines="None" >

C#

protected void Page_Load(object sender, EventArgs e)
  {
DataTable tb = new DataTable();
        tb = (DataTable)Session["ss"];
        GridView gv = new GridView();
        grv = (GridView)Session["gv"];
        grv.DataSource = tb;
        grv.DataBind();
        grv.Visible = true;
   }

The Datatable 'tb' however has rows.

I have a GV and Datatable in Page1. I use responce redirect to page2 and at the same time I want to retain the same status of both those controls with values. So I wanted to use this session method to bring to page2 and use them.

First create the session, suppose for the first request you can check 'Page.IsPostBack' property and for session check if(session["ss"] !=null)

protected void Page_Load(object sender, EventArgs e)
{
if(Page.Ispostback)
{
if(session["ss"]!=null && session["gv"]!=null)
{
DataTable tb = new DataTable();
tb = (DataTable)Session["ss"];
GridView gv = new GridView();
grv = (GridView)Session["gv"];
grv.DataSource = tb;
grv.DataBind();
grv.Visible = true;
}
else
Response.write("session is null");
}

After struggling an hour i got the solution I took two pages. below is mine firstPage code behind code.

protected void Page_LoadComplete(object sender, EventArgs e)
        {
            if (!IsPostBack)
                CreateSession();
        }
         protected void Button1_Click(object sender, EventArgs e)
         {
             Response.Redirect("TestAnything.aspx");
         }


        private void CreateSession()
        {

            DataTable tb = GetTable();
            GridView gv = new GridView();
            gv.ID = "MyGrid";
            gv.AutoGenerateColumns = true;
            Session["DataTableSession"] = tb;
            Session["MyGridinSession"] = gv;
        }

And On My secondpage i.e. TestAnything.aspx I put the following code

protected void Page_Load(object sender, EventArgs e)
 {
     if (!IsPostBack)
         AddGrid();
 }

 private void AddGrid()
 {
 GridView gv=(GridView) Session["MyGridinSession"];
 DataTable tb=(DataTable) Session["DataTableSession"];
 form1.Controls.Add(gv);
 gv.DataSource = tb;
 gv.DataBind();

 }

in Whole Of the code trick is in bolded text of second page that you need to add your grid control to form container....
Hope This Helps!!!
