Simple <Form> data error
 
Hello all,
I am trying to pass data between two files using POST method.
I am using Visual Studio 2008 and working in C# Environment to run this in ASP.net.

The code i am using is:
sareeweb.aspx

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="sareeweb.aspx.cs" Inherits="_Default" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>Untitled Page</title>

</head>

<body>

    <form id="form1" action="logink.aspx" method="post" runat="server">

    <div>

     

Name <input type="text" name="Name"/>

Age <input type="text" name="Age"/>

<input type="submit" />

 

    </div>

    </form>

</body>

</html>

logink.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="logink.aspx.cs" Inherits="logink" debug="true"%>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>Untitled Page</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

    <%

        string name, age;

        

name = Request.Form["Name"];

age = Request.Form["Age"];

Response.Write(name);

Response.Write(age);

%>





    </div>

    </form>

</body>

</html>

This is all what i am using and i keep getting errors on logink.aspx

Errors:
Server Error in '/sareeweb' Application.

It's a problem with the way ViewState is configured on the machine. Have a look at this: http://www.codinghorror.com/blog/archives/000132.html
