You can access the form control without having runat="server" you need to do following

  • The form method should be of type POST.
  • The tag should have an attribute called NAME. Because it is used as key in form[].
  • Html control should be access in code behind.

Html 

<form id="form1" runat="server" >   
    <input type="text" name="txtName" value="hidden text" />
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />   
</form>

C# Code:

protected void Button1_Click(object sender, EventArgs e)
{
    string s = Page.Request.Form["txtName"];
}

HttpContext.Current.Request.Form["foo"]
//Gets the input field with name foo
HttpContext.Current.Request.Files["foo"]
//Gets the dynamically added input type='file'

By using Request.Form["id"]` on Button_Click, you will get the value of html control

string id = Request.Form["id"]

You can try this

get a text area.

In Head use a java script function.

<script type="text/javascript">

        function getvalue(temp) {


            var imgcontrol = document.getElementById(temp);
            alert(imgcontrol.value);

        }
</script>

If you want to use in code behind so just take a value in hidden field & access it. in alert you will get value.I hope it help you.

Thanks

You can use ajax post to post your data from the client to the server code . You need to write a web method in asp.net page and user ajax post . here is an example
