I have created a Handler which return integer value after doing some database work. i would like to know how can i get that value and assign that value to Label by calling that handler.

I have googled it and most of the example uses Jquery.AJAX calls to retrieve the value. I am sure i can also get the value by using that. BUT for some limitation in my company i am restricted to use code behind.

Any example will help.

Handler: http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC
which returns: 3

need to assign this to a label control

i have tried this much so far.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Label1.Text = response.ToString() // this does not work

    OKay,pls note that if you want to use HttpWebRequest, be careful with the response.Header, you may have to specify some header information in order to retrieve the data. – Quannt Jan 25 '13 at 10:43

Use WebClient.DownloadString 

WebClient client = new WebClient ();
Label1.Text = client.DownloadString ("http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC");

You could also directly call your handler using ajax and update the label.

Here is a jQuery example:

$.get('Stores/GetOrderCount.ashx?sCode=VIC', function(data) {
  $('.result').html(data);
});

Try this

System.IO.Stream stream = response.GetResponseStream();
System.IO.StreamReader reader = new System.IO.StreamReader(stream);
string contents = reader.ReadToEnd();
