Looking for guidance: wanting to work with AJAX architecture



I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose. 

Well, I hope I've posted enough to a

Ajax Asyncfileupload doesn't work as soon as I put it in a control


Hi guys,

I can't get my <ajax:asyncfileupload> working and I don't see why...

When outside any panel or table it is working well, but as soon as I put it in a <asp:panel> or table I get a strange error which seems to be on client-side but I don't understand what's happen here. Here is the code and code-behind and Javascript.

Here's the error: 


Here's my front-code:

<%@ Page Language="VB" MasterPageFile="~/masterpages/mpSqueletton.master" AutoEventWireup="false" CodeFile="frmAdmGestSocietes.aspx.vb" Inherits="adm_frmAdmGestSocietes" title="Untitled Page" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>

<asp:Content ID="Content1" ContentPlaceHolderID="cphHead" Runat="Server">
<script type="text/javascript" language="javascript">    
        function uploadError(sender,args)
          document.getElementById("<%= lblStatus.ClientID %>").innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMes

Field validators does not work when field is manipulated with ajax

Hi.I have defined a field validator that works fine on normal behavior on a page:<asp:RequiredFieldValidator runat="server" ErrorMessage="errroooorr"  ControlToValidate="TextBoxHouseNumber" Display="Dynamic"></asp:RequiredFieldValidator>Now if I dont insert any text in the TextBoxHouseNumber field, and push submit, the FieldValidator fires as it should. But if I now click a button that automatically fills the TextBoxHouseNumber with text from a Jquery/Ajax function, the field validator still shows. It´s like "Hey, the user hasnt made any changes to the textbox, so I wont bother check it".How can I overcome this problem?Thanks alot! :)

Sharepoint2007 + Ajax slow work

Hello, I write Sharepoint WebPart with jQuery plagin jqGrid to show DB data in table view on Sharepoint Server 2007 (of cource to manipulate with data jQuery plagin use Ajax technology). It works fine, but I have a very important trouble with productivity, it's unacceptable for my project. As I see the trouble is that Ajax work very slow on Sharepoint. For test I wrote ASP.NET project with the same code and same data, user can get and update data less than 1 second, the same action on Sharepoint takes over 12 seconds. IT'S UNACCEPTABLE!!! Does any body can help me? Any suggestions...

jquery ajax call does not work after adding routes

Hi.   I've added routes to my asp.net 4 website so that, for example the page: "~/Main/About/Careers.aspx"  is mapped to the url:  http://localhost/mysite/careers/   I'm using jquery to make an ajax call and it simply does not work after I've added the routing, I used the following code, and it remains stuck on the spinner image:$.ajax({ type: "POST", url: "Careers.aspx/SubmitApplication", data: "{" + paramList + "}", contentType: "application/json; charset=utf-8", dataType: "json", beforeSend: function () { $(".applySpinner").show() }, success: function (msg) { $(".applySpinner").hide(); // Replace the div's content with the page method's return. if (msg.d == "") { $(".applySuccess").hide(); $(".applyFailure").show(); return; } else $(".applyFailure").hide(); $(".sentTime").text(msg.d); $(".applySuccess").fadeIn(1000); } }); Thanks.

Getting intellisense to work in VS 2010 for a ajax-enabled WCF Service


Hi all,

I'm experimenting with WCF services inside of a test project.  I have seen documentation on various blogs etc. that tell me that Intellisense is available for WCF services that I write.  However, I cannot get this intellisense to work in VS 2010.  I have tried the same simple steps in VS 2008 and can get intellisense working.

Has something changed here?  Is there a chance I am doing something wrong?

I create a new web application project.
I add an ajax-enabled WCF Service.
I add the script manager control to the page and then reference my wcf service.
When I go to create an object proxy to the service the intellisense is not available.
I know my code is working because I tested it.  It can call the web service and gets the expected result.  Just no intellisense.

I've also tried referencing intellisense from a separate .js file using the following technique:
/// <reference path="MicrosoftAjax.js" />
/// <reference path="MyService.svc" />

This has also not worked.  I have verified that my pathing information etc. is correct. 

Anyway, this is driving me nuts so I'm hoping somebody can shed some light on this.

Microsoft AJAX CDN

Content delivery networks (CDNs) are composed of "edge cache" servers that are strategically placed around the world at key Internet network points. These "edge cache" servers can be used to cache and deliver all types of content - including images, videos, CSS and JavaScript files.

Using a CDN can significantly improve a website's end-user performance, since it enables browsers to more quickly retrieve and download content. For example, instead of having a browser request for an image traverse all the way across the Internet to your web server to download, a CDN can instead serve the request directly from a nearby "edge cache" server that might only be a single network hop away from your customer (making it return much faster - which makes your pages load quicker).

AJAX GridView Checkbox Select All in ASP.Net

AJAX GridView Paging and Sorting using C# in ASP.Net

To enable the GridView Paging and Sorting to update the GridView Data without refreshing the ASP.Net web page AJAX Extension controls are used. UpdatePanel is used to hold the GridView control that triggers the events for the controls placed inside it. By Default UpdatePanel triggers the asynchronous postbacks for its child controls.

jQuery $(document).ready() and ASP.NET Ajax asynchronous postback

Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore. $(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback.
