I have a "submit feedback" form which uses "Ajax.BeginForm" to render a partial containing the form elements. The OnSuccess event is triggering even if the ModelState is not valid. Is this normal? I was expecting to be able to do a few postbacks resulting in an invalid model, then when the model is valid and there are no errors then the OnSuccess event would trigger? I handle this issue with a fairly simple javascript technique: First setup your OnSuccess like this: OnSuccess = "UpdateSuccessful(data)" Then your javascript function like this: function UpdateSuccessful(data) { if (data.indexOf(

i have a ajax request which works well using "POST" but when used "GET" it gives me the following error, {"Message":"An attempt was made to call the method \u0027GetSomething\u0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"} so here is my code, on the client side, function test() { $.ajax({ url:

I'm occasionaly getting the following popup from an AJAX.NET application Sys.WebForms.PageRequestManagerServerErrorException: An Unknown error occurred while processing the request on the server. The status code returned from the server was: 12031 From the Microsoft kb that status code indicates a ERROR_INTERNET_CONNECTION_RESET, but it doesn't state what was the underlying issue the triggered the error in the first place. How can I log/trace/etc the underlying error that generated the popup? It's a viewstate problem, but not related with time but with size. Try playing with maxRequestLength

I have a Button inside an UpdatePanel. The button is being used as the OK button for a ModalPopupExtender. For some reason, the button click event is not firing. Any ideas? Am I missing something? <asp:updatepanel id="UpdatePanel1" runat="server"> <ContentTemplate> <cc1:ModalPopupExtender ID="ModalDialog" runat="server" TargetControlID="OpenDialogLinkButton" PopupControlID="ModalDialogPanel" OkControlID="ModalOKButton" BackgroundCssClass="ModalBackground"> </cc1:ModalPopupExtender> <asp:Panel ID="ModalDialogPanel" CssClass="ModalPopup" runat="server"> ... <asp:Button ID="ModalOKButton" runat=

When you get a badge or aren't logged in to stack overflow there's a groovy little notification bar at the top of the page that lets you know there's something going on. I know the SOflow team use JQuery, but I was wondering if anyone knew of an implementation of the same style of notification system in asp.net AJAX. On a side note, what's the "official" name for this style of notification bar? I like it to. div tag with a fade. http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Walkthrough/UsingAnimations.aspx In this post ( http://www.pieterg.com/post/2010/05/24/ASPNET-and-Stackoverflow-Type

I'm having trouble dynamically adding controls inside an update panel with partial postbacks. I've read many articles on dynamic controls and I understand how to add and maintain them with postbacks but most of that information doesn't apply and won't work for partial postbacks. I can't find any useful information about adding and maintaining them with UpdatePanels. I'd like to do this without creating a web service if it's possible. Does anyone have any ideas or references to some helpful information? This is, I think, one of the common pitfalls for asp.net programmers but isn't actually that

I have an ASP.NET web page that displays a variety of fields that need to be updated best on certain conditions, button clicks and so on. We've implemented AJAX, using the ASP.NET Update Panel to avoid visible postbacks. Originally there was only one area that needed this ability ... that soon expanded to other fields. Now my web page has multiple UpdatePanels. I am wondering if it would be best to just wrap the entire form in a single UpdatePanel, or keep the individual UpdatePanels. What are the best practices for using the ASP.NET UpdatePanel? Multiple panels are much better. One of the
