am using session variables to store the value and accessing it in another form

C#

string name= Session["id"].ToString();
           Session["load"] = "2";
           Response.Redirect("sss.aspx");

the name has the value of session variable
in the sss.aspx form page load event

C#

Label1.Text = Session["id"].ToString();

this code throws an exception of "Object reference not set to an instance of an object"

Send me code where your are going to assign Session["id"] value before page redirect.

My view is your not assigning value to id session variable. Please check out the code.

hi RAGUNATH V,

Do you have 2 Session objects..? If not do the below.

Instead of Session['load'], please use Session['id'] = '2';

Thank you,
Vamsi

Right, thought so. Could you provide the page load of sss.aspx page..?

protected void Page_Load(object sender, EventArgs e)
{

Conn = new SqlConnection(ConnString);
string retriveString = "Select User_id,ID from Administration where User_id = '" + Session["id"].ToString()+ "' AND Designation='Rad'";
cmd = new SqlCommand(retriveString, Conn);
Conn.Open();
SqlDataReader red = cmd.ExecuteReader();
if (red.Read())
{
Session["dname"] = red[1].ToString();
}
Conn.Close();
Label1.Text = Session["id"].ToString();
}

Then use Server.Transfer() instead of Response.Redirect().
