Question

I have document.form1.submit() in javascript. I want to know how it’s received in code behind. In which class, in which method? Something like that. Coz I want to get the value inside a textbox to store it in session. And do i need an actual “submit” button for this to work? This really confuses me.

If i put it like this:

function CallSubmit() {
                var thetext = document.getElementById('textbox1').value;
                document.form1.submit(thetext);
            }

will I be able to pass the value of textbox1 to a specific method in code behind if it has, like, a receiving variable? I mean, how do i get the value of textbox1?

By the way, I’m trying to do this before the page unloads. Because I need to store the text from textbox1 so that I can re-assign that value back after the page refreshes.

Answer 1

You can get the post back values on code behind using the ‘Form’ as

Request.Form["textbox1"]

and if you read this Request.Form you get all data from post

Comments.
In asp.net we general avoid to use direct the Request.Form and we use asp.net controls that all ready handle the post values.

For example if you use an asp:TextBox with ID=textBox1 then you read the post from textBox1.Text
and if you like to read it using the Request.Form you need to call the Request.Form[textBox1.UniqueID]

The textBox1.UniqueID is the name value on the html control, and the name used for the post back.
