Forward and pass data along in Asp.net - asp.net

Question

In Asp.net Entity Framework I need to forward to another page and pass some data processed by the second page along.
In PHP I could do something like
<!-- page1.php -->
<form action="page2.php" method="POST">
<input type="hidden" name="id" />
<input type="submit" value="Go to page 2" />
</form>
<!-- page2.php -->
<?php
echo $_POST['id'];
?>
How can this be implemented in Asp.net?
Edit: There is a simple solution using Javascript and jQuery.
<!-- on page 1 -->
$('input[type=submit]').on('click', function (e) {
// Forward to browsing page and pass id in URL
e.preventDefault();
var id= $('input[name=id]').val();
if ("" == id)
return;
window.location.href = "#Request.Url.OriginalString/page2?id=" + id;
});
<!-- on page 2 -->
alert("#Request.QueryString["id"]");

Answer 1

There are, at least, two options:
Session state, like this:
Putting data into Session (your first page)
Session["Id"] = HiddenFieldId.Value;
Getting data out of Session (your second page)
// First check to see if value is still in session cache
if(Session["Id"] != null)
{
int id = Convert.ToInt32(Session["Id"]);
}
Query string, like this:
Putting the value into the URL for the second page as a query string
http://YOUR_APP/Page2.aspx?id=7
Reading the query string in the second page
int id = Request.QueryString["id"]; // value will be 7 in this example

There's a lot of ways to do this, take a look at this link for some guidance.
HTML page:
<form method="post" action="Page2.aspx" id="form1" name="form1">
<input id="id" name="id" type="hidden" value='test' />
<input type="submit" value="click" />
</form>
Code in Page2.aspx:
protected void Page_Load(object sender, EventArgs e)
{
string value = Request["id"];
}
MVC would look like...
#using (Html.BeginForm("page2", "controllername", FormMethod.Post))
{
#Html.Hidden(f => f.id)
<input type="submit" value="click" />
}
also, read through these MVC tutorials, you shouldn't blindly translate what you know in PHP to ASP.NET MVC, since you need to learn the MVC pattern too.

You can also use <form> with method="POST" in ASP.NET. And get value in code:
int id = int.Parse(Request.Form["id"]);
