There isn’t a magic bullet solution for what you’re looking for, unfortunately. Here’s what you can do: create an Interface class using this command in the Visual Studio Command Prompt window: wsdl.exe yourFile.wsdl /l:CS /serverInterface Use VB or CS for your language of choice. This will create a new .cs or .vb file. Create a … Read more
You should just use the full path in URL (started with http:// or at least with /) first of all. Internet Explorer works wrong in a lot of cases with relative urls. Some more small general remarks. You can use ajaxGridOptions: { contentType: ‘application/json; charset=utf-8’ } unstead of using loadBeforeSend. Some other default values (see … Read more
You can also implement by placing the code in Global.asax.cs protected void Application_BeginRequest(object sender, EventArgs e) { // Create byte array to hold request bytes byte[] inputStream = new byte[HttpContext.Current.Request.ContentLength]; // Read entire request inputstream HttpContext.Current.Request.InputStream.Read(inputStream, 0, inputStream.Length); //Set stream back to beginning HttpContext.Current.Request.InputStream.Position = 0; //Get XML request string requestString = ASCIIEncoding.ASCII.GetString(inputStream); } I … Read more
This is a known issue in .Net – Application_Error never fires for a web service. Not sure if there’s any reason it would be by design, but it just doesn’t work. Jeff Atwood had a post (and follow-up) about this a few years ago, with the following ideas: Put a try-catch block around each web … Read more
What is a “regular old fashioned web service?” An ASMX service, or are you using WSE as well? ASMX services are not naturally interoperable, don’t support WS-* specs, and ASMX is a technology that is aging very quickly. WSE (Web Service Enhancements) services DO add support for WS-* and can be made to be interoperable, … Read more
I faced the same issue, and included the below code to get it work. [WebMethod] [ScriptMethod(UseHttpGet=true ,ResponseFormat = ResponseFormat.Json)] public void HelloWorld() { Context.Response.Clear(); Context.Response.ContentType = “application/json”; Context.Response.Write(“Hello World”); //return “Hello World”; } Update: To get a pure json format, you can use javascript serializer like below. public class WebService1 : System.Web.Services.WebService { [WebMethod] [ScriptMethod(UseHttpGet=true … Read more
It may be possible to do this, but it would be a bit awkward. ASMX supports APM-style asynchronous methods, and you can convert TAP to APM (however, note that the MSDN example on that page does not propagate exceptions correctly). I have an example on my blog that shows how to wrap TAP implementations in … Read more
The delay that is experienced when a client is calling a webservice for the first time is caused by the fact that by default a XmlSerializers dll for the webservice needs to be compiled. This is causing the 2-4 seconds for the initial call. Of course this is the case when the webservice application is … Read more
Use this: var JsonString = ….; $.ajax({ type: “POST”, contentType: “application/json; charset=utf-8”, url: “YourWebServiceName.asmx/yourmethodname”, data: “{‘TheData’:'” + JsonString + “‘}”, dataType: “json”, success: function (msg) { var data = msg.hasOwnProperty(“d”) ? msg.d : msg; OnSucessCallBack(data); }, error: function (xhr, status, error) { alert(xhr.statusText); } }); function OnSuccessCallData(DataFromServer) { // your handler for success } and … Read more
Do you know that Page Methods are working properly? If you use the the ScriptManager do they work? It sounds like you might be missing a web.config entry. Specifically the HttpModules section.
