Running ASP.NET 3.5 on Mono 2.6.7 (Debian), AjaxControlToolkit throws the following exception on startup: "Cannot cast from source type to destination type." (see stack trace below) This is a simple website referencing AjaxControlToolkit (so long as it's referenced, it will fail throwing this exception). On .NET 3.5, the same simple webpage referencing AjaxControlToolkit.dll would run fine. How would you get this to run on Mono? <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register assembly="AjaxControlToolkit" namespace=

I have used ajax update progress control that shows the animated gif when postback happens. Problem: It displays for a while but then it stops refershing (or rather, stops playing/revoloving). What could be the actual cause of the same? Please advice!. Thanks! Jourdan The animation of a .gif will stop on PostBack with Internet Explorer. The problem is inherent to Internet Explorer. Apparently this issue goes all the way back to IE 6 (though I've only confirmed it in IE8). There is a little hack around it, and that's by updating it's source with a setTimeout function UpdateImg(ctrl) { var img =

I'm building a shopping cart page that could potentially contain dozens of separate items. Each item has a collapsible panel that contains several form elements that can be used to customize it. Most of the cart is wrapped in an UpdatePanel so that I can avoid a full postback when the user makes changes. When there are many items in the cart, there are of course many many postback elements, all of which are included in the raw form post, even though each post is really only triggered by the change of a single element (ChildrenAsTriggers=True). I find that the uncompressed size of the redundant

I am using ajax enabled WCF, when i open the url in web browser i am getting this error. The message with Action ' http://localhost:22219/MobileService.svc/GetProductCategories ' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None). MobileService

Say I have 2 UpdatePanels on the page and each UpdatePanel has a one server Button each. When I click on the first button and then the second button and look in Firebug, I see that the 2nd async postback is not triggered until the first one completes. Is this working as expected? My understanding was with AJAX postbacks, the event handlers for the buttons trigger simultaneously. EDIT: Any help anyone? It is accurate for that model. You probably want pagemethods. EDIT: drachenstern says "finally back at my computer" Here's the thing: An UpdatePanel is fundamentally a page-postback. It can only

I am having a pagemethod to which i give a call from my JavaScript say Pagemethods.MyMethod(MyParameter, onsucess, onfailure); In the Code behind, I have something like this: [WebMethod] public static void MyMethod(Param) { try{ //DoSomething.. } catch(exception ex) { //Log the exception and rethrow throw new exception(ex.innerexception); } } Now the issue i face is : Whenever i do get an exception, i re throw the exception from code behind But in the onfailure method, i just get a generic message saying that "the server method MyMethod failed with following error: " I don't seem to get the

I am using an asp.net text box inside ajax update panel. If I enter &# in the textbox and press Save Button , it gives a javascript error Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500 Please help me why this error appears? This issue sometimes occurs when you have a control registered as an AsyncPostbackTrigger in multiple update panels. If that's not the problem, try adding the following right after the script manager declaration: <script type="text/javascript"

I have a form which is in an updatePanel and I have a span with hidden loading image, which I want to show when user clicks to submit button but I first need to check if page is valid on client side. Also I'm making loading span visible with jQuery. Here is my code: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function showLoading() { $('#loader').show(); } </script> </head> <body> <asp:ScriptManager ID="smMain" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="upForm" runat=
