C# - Ajax Enabled WCF Service Not Defined / Value Must Not Be Null For Controls And Behaviors
Feb 12, 2010
[URL] I created an AJAX-enabled WCF service to call from a web form. the thing is that after creating it, I'm able to populate my dropdown from the items returned by the service.
but 2 hours later, I get this FireFox error message when loading the page :
"Error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element
Source File: http://localhost:50403/ThunderWeb2 /ScriptResource.axd?d=Htwz5SPOGy46DsuOfFL3pQa8Lr5_3hMVD_cps_d3FYg4iWXeG_0-3bdA95LxuQtbXGUXoHUpV1SV8q4FusAyWjJpsaLk2b6TFO_NfpB_3ro1&t=ffffffffbb99ee49
Line: 2710"
and also this :
Error: ThunderServ is not defined
Source File: http://localhost:50403/ThunderWeb2/Thunder/new_recording.aspx
Line: 105
I delete the service and recreate it with the same code and then it runs fine. but after a while, (1 hour or so), the service isn't defined anymore, I get the error.

I have this Aja.svc in my root folder
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Aja
{
[WebGet]
[OperationContract]
public string Hi()
{
return "hi world!";
}
}
and I'm trying to do this: $.get('Aja.svc?method=Hi', function(d) { alert(d.d); }); In firebug I see that the result is HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. I use .net 3.5, jquery 1.4.4

Scenario : I am going to access external web service [ExternalWS] using AJAX. So obviously, need to create local proxy service [LocalProxyWS] first, which in turn will access the external web service. Now, the external service webmethod [Process] basically redirects the current page on our site to their site, does some work and then return back to our site.
What I want : I want that when the user clicks the button ('Process') on our site, it should open a new window and then starts executing the request on the new window, so that I can have the page on my website to be displayed permanently (which will poll a request every 15 seconds to the external service (via local proxy) for the status).
Local Proxy service which calls external service is as follows..
[ServiceContract(Namespace = "LocalProxy")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class LocalProxyToExternalService
{
[OperationContract]
public void InitiateTransaction(string amount)
Basically, I am opening a new window from the button click and then want to process the new request in that new window, so that I can show the status to the user from the current page on my website So far, it opens the new window, but doesn't transfer the request on to that, but I get an error message in firebug as follows...

I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?

I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.I can access the proxy class from metadata, and it's of typeSystem.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.I realize that this is all old technology, but I don't get to decide what the servers run :(

I use AJAX controls a lot - AJAX update panels, AJAX-enabled grids, etc. (mostly from Infragistics), and most of the time, things work great. But sometimes they don't, and I have no idea where to start with debugging etc. The AJAX part of it is a black box (seemingly), and I really don't like that. I want to know enough about AJAX and javascript such that I have confidence to work with these controls instead of just praying that they work. I want to be able to debug them, and also have confidence that I am using them properly (because I don't feel I can possibly use them really properly and appropriately if I don't know what they are doing). What do I need to know to get this comfort? Where can I learn about this? How should I go about tackling learning about this?

I know this is a silly question, but I need to ask it. If we are adding Ajax update panels to several pages of an app and adding javascript to pages, the app will use more of the clients local memory, right?

I use Visual Web Developer 2008 Express. I am following a tutorial which uses VWD2005 and says to create an Ajax enabled website. There is no specifically named "Ajax enabled template" in VWD 2008 Express
I think I have created one by creating a new ASP.NET website and adding a ScriptManager and an UpdatePanel to the page and placing the content of the page inside the UpdatePanel ContentTemplate.
I am trying to rule out reasons why my aplication wont work - step by step, piece by piece, from the beginning of the tutorial.

I've asp.net 2.0 ajax enabled web site in which I used Ajax update panels in pages. Now I want to convert it into asp.net 3.5 but it gives errors for Ajax tool kit and script manager and update panel used in pages. I don't want to remove ajax functionality from my site, so is there a way to convert them without removing ajax update panels from pages.On my PC I've installed both VS2005 and VS2008.

Although I've installed Ajax Toolkit, and Ajax minifier on both VS 2008 and 2010, but I can't make Ajax-enabled website at home.

I have a website in my hands that wasn't developed entirely by me, and i wanted to add some ajax controls to it (update panel would be the first).
how do i know if my site is already ajax enabled?
And third, in case it is not, what should i do to enable it? I understand this must be a question that has been posted many many times, and i have read some topics with it, but i couldn't quite figure out what to do.

I came across this amazing website built in asp.net and AJAX. Just look at how the pages are. Its amazing. When you add products into shopping cart, it immediately gets added without a postback and there is a sweet little Tooltip that indicates that the item has been added.
Plus, when I click on the 'Login' link, that nice shadow window pops up with the opaque background.
Heres that Ajax-enabled website I came across:

I need to Ajaxify my website and add similar features like this one.
