I want to submit a form residing on other domain from my asp.net appliocation and then get result in my asp.net page(response). I have tried the way in which HTTPWebRequest and HTTPWebResponse objects were used, but no success.
For more clarity, i want to send a container no. to a website providing container tracking and get the result page html in my control.
There is no authentication there. Webite url is "http://www.concorindia.com/containerquery.aspx". Is there any other way to accomplish this?

I am using the code:

1. string url = "http://www.concorindia.com/containerquery.aspx";
2.
3. WebRequest request = WebRequest.Create(url);
4.
5. request.Method = "POST";
6.
7. string postData = "contno=123456&CONTButton1='Submit Query'";
8.
9. byte[] byteArray = Encoding.UTF8.GetBytes(postData);
10. request.ContentType = "application/x-www-form-urlencoded";
11. request.ContentLength = byteArray.Length;
12. Stream dataStream = request.GetRequestStream();
13. dataStream.Write(byteArray, 0, byteArray.Length);
14. dataStream.Close();
15.
16. WebResponse response = request.GetResponse();
17. dataStream = response.GetResponseStream();
18. StreamReader reader = new StreamReader(dataStream);
19. string responseFromServer = reader.ReadToEnd();
20. response.Wtrite(responseFromServer);

0	Hi Asad1605, I modified your code a bit and its working for me. For testing purpose I kept a TextBox in my aspx page <asp:TextBox ID="txtBox1" runat="server" TextMode="MultiLine" Rows="20" Columns="100" /> and in my Code behind page page load, I wrote following code and it gave me complete html page from the website you mentioned. Use following namespace apart from default that comes in the code behind. using System.Net; using System.IO; using System.Text; protected void Page_Load(object sender, EventArgs e) { // EmailSender.SendEmail("info@itfunda.com", "", "", "Subject", "Body", System.Net.Mail.MailPriority.Normal, false); string url = "http://www.concorindia.com/containerquery.aspx"; WebRequest request = WebRequest.Create(url); request.Method = "POST"; string postData = "contno=123456&CONTButton1='Submit Query'"; byte[] byteArray = Encoding.UTF8.GetBytes(postData); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = byteArray.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); WebResponse response = request.GetResponse(); dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); string responseFromServer = reader.ReadToEnd(); txtBox1.Text = responseFromServer; } There were some typo in your code, hope this will help you.

Hi Asad1605,

I modified your code a bit and its working for me. For testing purpose I kept a TextBox in my aspx page

<asp:TextBox ID="txtBox1" runat="server" TextMode="MultiLine" Rows="20" Columns="100" />

and in my Code behind page page load, I wrote following code and it gave me complete html page from the website you mentioned.

Use following namespace apart from default that comes in the code behind.
using System.Net;
using System.IO;
using System.Text;

protected void Page_Load(object sender, EventArgs e)

    {

        // EmailSender.SendEmail("info@itfunda.com", "", "", "Subject", "Body", System.Net.Mail.MailPriority.Normal, false);



        string url = "http://www.concorindia.com/containerquery.aspx"; 

 

         WebRequest request = WebRequest.Create(url); 

 

         request.Method = "POST"; 

 

         string postData = "contno=123456&CONTButton1='Submit Query'"; 

 

         byte[] byteArray = Encoding.UTF8.GetBytes(postData); 

         request.ContentType = "application/x-www-form-urlencoded"; 

         request.ContentLength = byteArray.Length; 

         Stream dataStream = request.GetRequestStream(); 

         dataStream.Write(byteArray, 0, byteArray.Length); 

         dataStream.Close(); 

 

         WebResponse response = request.GetResponse(); 

         dataStream = response.GetResponseStream(); 

         StreamReader reader = new StreamReader(dataStream); 

         string responseFromServer = reader.ReadToEnd();

         txtBox1.Text = responseFromServer;

    }

There were some typo in your code, hope this will help you.

Thanks for asking question.

0	Thanx Sheo. The html you are getting is of the page that is to be posted, not of the result page. I want to post this page with the values stored in "postData" variable. i am trying to get the html of page that will come after this page. You can see the page "http://www.concorindia.com/containerquery.aspx" in ur browser to understand what i want.
