I'm using the [System.Web.Script.Services.ScriptService] tag to use web services callable from client side javascript. What I need is a way of globally logging any unhandled exceptions in those methods. On the client side, I get the error callback and can proceed from there, but I need a server-side catch to log the exception. The guy at this url: http://ayende.com/Blog/archive/2008/01/06/ASP.Net-Ajax-Error-Handling-and-WTF.aspx suggests that this can't be done. Is that accurate? Do I seriously have to go to every single webmethod in the entire system and try/catch the method as a whole.

I'm using UpdatePanel to asynchronously call a button click event in a page that calls a method in another class which writes out an XML file on the output. Is there a way to do this with JQuery instead of UpdatePanel? Use jQuery to handle the click event. Then call a page method in the code-behind using this technique . From there you can write the XML file or do whatever else you want. Aleris A simple alternative way to using jQuery to do ajax without the update panel is to use a build in mechanism of ASP.NET called 'page methods'. By decorating a static method in the page behind with

I have the following method in controller [HttpPost] [Authorize(Roles ="Klient")] [ValidateAntiForgeryToken] public ActionResult GetAvaiableHouses(DateTime startDate, DateTime endDate) { Session.Remove("Reservation"); IEnumerable <SelectListItem> avaiableHouses = repository.GetAllNamesAvaiableHouses(repository.GetAvaiableHousesInTerm(startDate, endDate)); List<string> houses = new List<string>(); avaiableHouses.ToList().ForEach(item => houses.Add(item.Value)); if(avaiableHouses.ToList().Count == 0) { return new EmptyResult(); } Session["Reservation"] = new NewReservation() { StartDate =

I have an application that shows a list of items. The user can click on an item and see its details in a modal popup (centered DIV, shown using JavaScript). I need to have a button on that popup that will allow the user to print out the contents of the modal popup only. This is for an internal application that needs to work in IE7+ only. When the user clicks the print button on the modal popup the state of the item gets changed to "printed" (for internal business reasons...). I am using ASP.NET and the ASP.NET AJAX Control Toolkit ModalPopupExtender , but I am guessing that the technique to

If you don't know what the operation aborted error is, here's a Microsoft KB Article about it, http://support.microsoft.com/default.aspx/kb/927917 . There's also tonnes of posts about it but the simple answer for it's occurrence is this; the error only occurs if you try to manipulate a DOM element via JavaScript before the element you are trying to manipulate is loaded. I know how Internet Explorer's (IE) infamous Operation Aborted occurs and know how to fix it. The problem I have is a very weird scenario. Testing locally and on a development machine with IE7, I never ever get the operation

How do you use a progressbar to show the loading percentage for a page? ...(similar to how they show in flash) Thanks Impossible(on IE8 & FF3 & Opera without plugin or extension). If you want real loading percentage include HTML + Javascript + Stylesheet + Image. you can only detect how many file loaded to page(only Image & javascript can be detected by this technique). I would say that if you need a progressbar for a page, that page might need some rethinking. Personally I don't like pages that have progress bars (Like the one in the ASUS Download Area). They are just annoying. My browser
