Hi,

I am typing some text in html text box.
Without giving runat ="server" how can I insert this into table using C#?

If I give runat ="server" I have to give in C# like

session["user"] = txt.value;

I want to know how to do it without using runat="server"

Hi,

you can do by using Jquery or basic xmlhttprequest.

JavaScript

  $.get("Default.aspx?action=getusername",{username:$("#txt").val()},function(data){
   $("#txt").text(data);
});

In code behind you've to write code

C#

//under pageload of default.aspx
if(request.Querystring["action"]!=null)
{
  response.clear();
response.write(Session["user"].tostring());
response.End();
}

without this that is not possible in my view

All the Best

but i want to display it textbox.not in div i tied that also its working fine.i want to store the text box value in a session.
<input type="text" id="resdiv" /> instead of div i took this

function addthis(tid, val1) {
if (tid.checked) {
document.getElementById("resdiv").innerText = parseInt(document.getElementById("resdiv").value) + parseInt(val1);
// document.getElementById("resdiv").style.visibility = 'hidden';

//document.getElementById("<%=hid.ClientID %>").value = document.getElementById("resdiv").innerText;
alert("hellop");
}
else {
document.getElementById("resdiv").innerText = parseInt(document.getElementById("resdiv").value) - parseInt(val1);
}
}

give runat="server" then store it in session

or use jquerypost method to post textbox value to server.
whenever the data in textbox changed.

As others have said, there is nothing wrong with Runat="server".
Perhaps if you gave us a reason why you do not wish to use it we could give more specific answers.

If you always want that value on the server side, and you want it to be updated (via a page refresh in ASP's 'special' style) when the user changes it, you should use runat=server. Values which are supposed to be submitted and mirrored in server code are exactly what runat=server is designed for.

Why you don't want to use runat="server"??

anyways here is the solution :-

You can use

var txtvalue = document.getElementById("txt").value;

but still you have to save this value (txtvalue) into any hidden field for further use in code behind.

Like:-

var txtvalue = document.getElementById("txt").value;

document.getElementById("<%=HiddenField1.ClientID %>").value = txtvalue;

Now you can use this hidden field value in code behind.

Like :-

session["user"] = HiddenField1.value;

--------------------------
You can also get value by this also :-

session["user"] = Request.Form["txt"];
