I am trying to post data with no success

[hd95]

I am trying to post data from C# using the code below. When I run the code with httpwatch running all that gets posted is the button action and .Net eventvalidation and viewstate data. Ideas anyone?

 
          ASCIIEncoding encoding=new ASCIIEncoding();
           string postData = "subject=test";
           postData += ("&description=test");
           postData += ("&domain=XX"); 
 
            postData += ("DOMAIN_NAME=XX");
            postData += ("&logonDomainName=AD_AUTH");
 
            postData += ("&username=XXX");
            postData += ("&password=XXX");
 
 
 
byte[] data = encoding.GetBytes(postData);
 
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.Method = "POST";
myRequest.ContentType="application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream=myRequest.GetRequestStream();
// Send the data.
newStream.Write(data,0,data.Length);
newStream.Close();
 
 
//Get the response handle, we have no true response yet!
HttpWebResponse WebResp = (HttpWebResponse)myRequest.GetResponse();
//Let's show some information about the response
Response.Write(WebResp.StatusCode);
Response.Write(WebResp.Server);
 
//Now, we read the response (the string), and output it.
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
 
Response.Write(_Answer.ReadToEnd().Replace("<","&lt;").Replace(">","&gt;"));
 
        }
