copied!<p>In your ashx, you need to get the data from reading the post data... </p> <pre><code> StringBuilder HttpInputStream; public void ProcessRequest(HttpContext context) { HttpInputStream = new StringBuilder(); GetInputStream(context); // the data will be in the HttpInputStream now // What you might want to do it to use convert it to a .Net class ie, // This is using Newtonsoft JSON // JsonConvert.DeserializeObject<JsonMessageGet>(HttpInputStream.ToString()); } private void GetInputStream(HttpContext context) { using (Stream st = context.Request.InputStream) { byte[] buf = new byte[context.Request.InputStream.Length]; int iRead = st.Read(buf, 0, buf.Length); HttpInputStream.Append(Encoding.UTF8.GetString(buf)); } } </code></pre> <p>In your response back the caller - your ashx needs to respond in JSON so the caller JavaScript can consume it. </p> <p>I suggest using Newstonsoft JSON eg...</p> <pre><code> public void ProcessRequest(HttpContext context) { // read from stream and process (above code) // output context.Response.ContentType = "application/json"; context.Response.ContentEncoding = Encoding.UTF8; context.Response.Write(JsonConvert.SerializeObject(objToSerialize, new IsoDateTimeConverter())); } </code></pre> <p>OR to make it really really easy, change to - basically needs to respond back in JSON for the JavaScript handler to process it</p> <pre><code> public void ProcessRequest(HttpContext context) { context.Response.ContentType = "application/json"; context.Response.Write("{data:\"Reply message\"}"); } </code></pre>
