how to call ASHX handler and getting the result back

Question

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

Answer 1

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();
