The caught exception is in the form of a JSON serialized string, plain text or HTML. If it is a JSON string, then it is parsed and converted into a JSON object and the details of the exception are extracted.The details of the exception are then displayed using jQuery UI Dialog modal popup.

Here are a few examples: [WebMethod] public static string GetLog() { DAL.LogService log = new DAL.LogService(); string items = log.GetLog(); return items; } [WebMethod] public static void ClearBenchmarks() { DAL.LogService log = new DAL.LogService(); http://stackoverflow.com/questions/29606617/ajax-webservice-in-asp-net-how-to-global-error-handling log.ClearBenchmarks(); } [WebMethod] public static void WriteLog(string message1, string message2, string user, string type) { DAL.LogService.WriteLog(message1, message2, user, type); } In fact in the most time, they only redirect to the dataLayer of my application, but in fact, ofc, I have 50+ single methods... Now I want to include error handling in my application - how to do that globaly without having try catch in every single method? .net ajax error-handling webmethod share|improve this question asked Apr 13 '15 at 13:31 Kovu 5,0122474132 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted I found this solution on another website after long search. In fact the Application_Error is never handled because the Request Handler will filter the JSON Request out before it even reaches this point, so your only chance (afaik) is to step into the Request Handler and check if there is a jsonerror in it. Works very fine for me, just add the global.asax.cs and copy paste this code at the end of it: protected void Application_PostMapRequestHandler(object sender, EventArgs e) { HttpContext context = HttpContext.Current; if (context.Handler is Page && !string.IsNullOrEmpty(context.Request.PathInfo)) { string contentType = context.Request.ContentType.Split(';')[0]; if (contentType.Equals("application/json", StringComparison.OrdinalIgno

The aim is to detect and handle errors in JavaScript avoiding embarrassing mistakes and sometimes even blocking your web client. Prerequisites We assume that our readers have a good level of knowledge with the .NET platform and the ASP.NET and AJAX technologies. In addition, note that this tip is based on our example on the Framework.NET 3.5 with the Microsoft Visual Studio 2008 IDE. ASP.NET error management with the Global.asax file The Global.asax file offers us the opportunity to centralize the management of errors by capturing any unhandled error in our web application. This latter example allows us to redirect our user to a personalized web page, that will handle the error based on its type. If for example we get an error in the click event of a button in ASP.NET: protected void btn_Click(object sender, EventArgs e) { throw new Exception("Exception générée pour test !"); } The exception is not handled in the method, but it can always be taken in the method "Application_Error" of the "Global.asax" file: protected void Application_Error(object sender, EventArgs e) { // Capture last error Exception exception = Server.GetLastError().GetBaseException(); try { // Load error in memory Context.Session["Excep"] = exception; // Redirect request this.Response.Redirect("~/PageDErreur.aspx"); } catch (Exception innerEx) { string errorMsg = "Une erreur s'est produite lors du traitement de l'exception : " + exception.Message + ". "; errorMsg += Environment.NewLine + innerEx.ToString(); } } Of course, we must always add to our management function: an error log and if necessary a case by case treatment depending on the type of exception thrown. Finally, we can redirect our user to a web page displaying an appropriate error message. Handling errors occurred at client-side [AJAX technology] When working with AJAX technology, it always tends to enrich our web client with JavaScript code, which increases the risk of errors at the client. It would then be necessary to capture
