There are three ways:
1) Query string: values after a '?' as part of the page URL.

http://www.codeproject.com/Questions/811654/How-to-get-the-text-box-value-form-one-page-to-ano?arn=4

arn is the variable name, 4 is the value.

2) Cookies: stored on the client, they can be recovered by the server and used in the new page load event.

http://msdn.microsoft.com/en-us/library/aa287533(v=vs.71).aspx[^]
3) Session: stored on the server.

I am wrong at my explanation above. What I mean is that the user will input their username at first inside the text box in the first page. the the User will select the RESET ID which is a link to the next page. Now, the text box on the second page will display the username of the user. How to do that? I tried to use the session, but I got an error saying,"Object reference not set to an instance of an object"

How did you try to use the Session?
What code, and where?

DarkDreamer08 26-Aug-14 20:18pm

on my first page, I included a session on the page load. Here is my code in that part:
//My connection to the database
if (cnt == 1)
{
if (userName == uname.Text && pass == password.Text)
{
if (u_type == "admin")
{
Session["uname"] = uname.Text;
Response.Redirect("admin.aspx");
}
else
{
Session["uname"] = uname.Text;
Response.Redirect("CS.aspx");
}
}
else if (userName == uname.Text && pass != password.Text)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "popup", "alert('Invalid password');", true);
password.Text = "";
}

and in my second page, I just put this line at the page load event:
username.Text = Session["uname"].ToString();

Please correct me if I did something wrong. Thank you!
