Making A WCF Call With AJAX?
Mar 12, 2010
Is it required to use a RESTful service to be able to make a ajax call to a wcf service (for example: by using WebInvoke attribute on Operation contracts). Once a service is made RESTful by adding a webHttp binding on the service host, can the host have other endpoints as well? (wsHttp or netTcp). Is it required that the aspNetCompatibilityEnabled be set to true for a service that has webHttp binding (and can this setting coexist for other endpoints). I understand I can use both JQuery and ScriptManager for making WCF calls on the client. Why should I use one over the other?

I accept both C# and VB.NET
If you visit this [URL] and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I'd like to do the same but ASP.NET and jQuery.

I have a Page that expects a POST Request and returns some JSON. Essentially it's an .ashx Page, but that doesn't really matter.
When using jQuery, I would use jQuery.Post with "json" as dataType to simply make the POST request and get an object back. However, for the current project I mainly use ASP.net AJAX and I don't want to add jQuery just for the call.
For ASP.net AJAX, I only found information on how to call a "traditional" web service though, which means adding a asp:ServiceReference to the ScriptManager and having a "real" Web Service at the end.
Is there a simpler way to make a POST call to a Page? I could live with getting the raw JSON and then manually eval()ing it, but I don't want to create a full asmx web service (deploying them on SharePoint is a bit painful, and my ashx handler works fine)

I tried to take advantage of jQuery AJAX call to enhance user experience but I am facing a tricky problem.
When the user does nothing for a period of time, e.g. 30 minutes to reach authentication timeout, making AJAX call becomes the problem. The server side will return login page and display in my target div section. The simplest solution I can think of is to inject a dummy tag in login page, and when detecting such dummy tag then use javascript to redirect to login page. But this means that I have to do that every time I make AJAX call.

For an Umbraco project, I am trying to make a simple Ajax call.. I can't use PageMethods because I need to make the call from inside a UserControl.. I tried to do it via web service call like this:
Web service method:
[System.Web.Script.Services.ScriptService]
public class MapService : System.Web.Services.WebService
{
[WebMethod]
[Code]...
The problem is, "MapService.GetCities" method doesn't get invoked..
What might be the problem here?
Alternatively, what is there any better way to make these kind of Ajax calls in a User Control?

I am just wondering that, is there anyway to make an Ajax request using jquery ("$.ajax") and making partial rendering without using the .NET Ajax framework (without script manager).
I have tried this before, but it's executing the page_load every time and not reaching to the pagemethod.

I've created a sign up form in a normal .aspx page, with some TextBoxWatermarkExtendes, PasswordStrength, RegularExpressionValidator, and more..it worked perfectly..I have inserted it all inside the modal content div in this SimpleModal:http://www.ericmmartin.com/projects/simplemodal-demos/(the OSX style dalog)
the First problem:I have a toolkit script manager, and an update panel surrounding the "username" textbox, with enabled autopostback, so it checks if user is taken or not when the textbox looses focus and shows a message in label..when it runs for the first time (when it's working) first of all, the passwordStrength control doesn't work, secondly, after I type something in the username textbox and make it lose focus (press tab or click outside), it's watermark text of course gets deleted when i focus on it, and another watermark text from another textbox gets deleted (i dont know why) SO after like 1 or 2 seconds, the text I wrote gets deleted and replaced by the watermark, for BOTH textboxes that had watermarks
Second problem:the first time, the it works normal, but when I close the modal and open it again, the textBoxWatermark changes to a normal text inside the textbox, even the "Sign up" button stops working, and expression validators and required validators and stuff stop working..

I have a GridView control inside one Update Panel and a detail section inside another Update Panel. Initially, the detail section is hidden and when a GridView row is selected, the Detail panel becomes visible. Everything works fine except that if the GridView contains more rows and covers most of the user's screen, screen doesn't shits to the start of Detail section.I can use anchor but was just wondering if there is any other way of achieving this. Also the Detail section has multiple nested Update Panels and if I use anchor, then any of the child Update Panel's update will move the screen to the beginning of the detail Section.

My current code is costing performance issue when ran on server.
ISSUE:
I've a a textbox whixh is invisible by default and a button, which is visible and both are placed inside grid's item template
I've also used ajax's update pannel to supress postback
My requirement is to make thetext box visible on button click which is working fine and fast in the localhost machine
But when put on server,its taking considerably more time to make the text box visible.

I created some buttons and a label inside UpdatePanel. Upon clicking the buttons Label's text changes as configured. Lovely. Now how do I go about making a bigger piece of content change (without page refresh) using the same buttons? (Basically I'm trying to build Ajax tabs)I tried making the button click event change ContentPlaceHolderID value on some Content controls but that doesn't seem to work.

I'm going on my 3rd day trying to get my Ajax AutoComplete textbox to call my web method. Based on my google searches, I'm not alone. I suspect the problem has something to do with the ServicePath property on the extender, although I'm not sure. My web service is at the same level, on the same server as my test web page. I'm not sure exactly what should go into the ServicePath property, although I think I've tried every possibility. Below is my web service followed by my script.

The following .post command in a .js file works fine in Dev and Test but not on our production box (Windows Server 2003). I believe the URL is not being found on the production box since the function(result) is not being run. Or it could be that the index method is not returning the jsonresult.
