How to get html input value in code behind?

 Hello all,

I have dynamically created <input type="text" > in client side.

the id for such generated input type text are say price1,price2,price3 and so on.

What i need is to retrive the value of those input text boxes in code behind?

Note that those controls are simple html <input type="text"> not server controls.

With Request.Form["price1"] you will get the name of the textfield with id price1.

If you are using VB.NET then the syntax is: Request.Form("price1")

 There is no straight forwrsd methods to retrieve the value of an input control unless you say runat="server".

My suggestion is to use the runat="server" tag and try getting the value using VALUE property.

Otherwise you can use Page.FindControl('<input control id>') and see whether the control is returining other than null...then i feels that will work.

if you are using ajax or maaster-content page then the controls id will be not the one you make sure you are giving the correct id itself (using view source of the page)

 he is the MAN....

or you can set your html controls as server control.. by adding runat='server' in yout html input control.. you can acess these controls on your code behind as you access your server control...

If you are using VB.NET then the syntax is: Request.Form("price1")

this does not work

<input type=text id=mytag value=test />

 value = Request.Form("mytag")


This does:

 <input type=text name=mytag value=test />

 value = Request.Form("mytag")


In short give the html tag the NAME attribute that you wish to access using the request form.


<%page language="vb"%>
<script language="vb" runat="server">
 sub btnshow_click(sender as object, e as eventargs)
 end sub
<html><head><title>Html Input Example</title></head>
<form id=form1 runat=server>
<%="<input name='mytag' type='text' value='' />"%>
 <asp:button id='btnshow' onclick='btnshow_click' text='Show'
runat='server' />

 Point being 'runat=server' is not required
