I am hitting a url using http post with certain parameters and upon hitting url a box appears which asks for username and password . For now i am pasting the url in browser and on entering it asks for username and password.

I want to do this using asp.net when i know how to send request to url but i want to know how can i automatically enter username and password using code . Thank You

What you are looking to do is send a POST request to the server with the username and password. Most servers will not accept a direct authentication request and will require to have a few Http headers like cookies, referer to be set before it.

You can use a tool like fiddler to see what your browser is actually sending to the server.

Here is a small sample to send post data to the server.

// create the POST request
var postParams = "user=userName&password=userPassword";
var webRequest = (HttpWebRequest)WebRequest.Create(yourUrl);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = postParams.Length;

// send POST data
using (StreamWriter sw = new StreamWriter(webRequest.GetRequestStream()))
{
    sw.Write(postParams);
}

EDIT: This is this simplest method to set the basic authorization header

webRequest.Credentials = new NetworkCredential("userName", "userPassword");

The link you provide says that they use basic HTTP authentication.
