Using Jquery To Call A WCF Data Service From The UI Violating The MVC Pattern?
May 26, 2010
I'm fairly new to ASP.Net MVC 2 and understand the MVC pattern in itself. But my question is what's the best way to populate dropdownlists in the UI sticking to the MVC pattern. Should I be going through the controller? Every article I've seen to do this shows how to do it using javascript and jquery. I have a test application that I'm re-writing in MVC2 I have my dropdowns working with jquery basically calling a WCF Data Service that returns JSON which populates the dropdowns. Seems to me though that this is bypassing the controller and going straight to the model therefore strictly violating the MVC pattern. Or am I missing something obvious here. You thoughts or best practices would be greatly welcome here.

I have created an WCF data service in a new asp.net web application and i want to call this web service from another web application using jquery, but it always returns null.
My jquery call looks like this:
[code]....
Note that [URL] works in the browser but since the jquery call is from localhost:3410 i assume its a problem with cross domain.
I have been reading that i should use jsonp for this, but i have a hard time figuring it out.

I'm trying to call a web service and the passed string may have punctuation, depending on what the user types in.I currently have an HTML textbox and a jQuery call to the .NET web service. I definitely think the string with punctuation fails because jQuery will send the string wrong, so I tried a few different javascript encoding functions I could find. I was never able to encode it successfully and decode it in .NET, saving the string with punctuation.
Basically I have a textbox that a user can update their status in. If the user wants to use punctuation, I'd like them to be able to. How can I accomplish this with jQuery and .NET?

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

I am trying to use the below code to call a wcf service method for Autocomplete functionality in a TextBox. I have written the following query:
$(document).ready(function () {
$("#<%= txtCompany.ClientID %>").autocomplete [URL], {
dataType: 'json',
parse: function (data) {
var items = data.d;
var parsed = [];
for (var i = 0; i < items.length; i++)
parsed[i] = {
data: [items[i]],
value: items[i],
result: [items[i]]
};
return parsed;
}
});
});
The same query works if I pass a Java Script array variable instead of the wcf service method. The wcf service method contract is:
[OperationContract]
[WebInvoke(Method = "GET", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json)]
string[] GetTestCompanyList(string prefixText, int count);

I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is [URL]). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Some of the changes I made was adding the following to the Operation Contract:
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "SetFoo")]
void SetFoo(string Id);
Then this above the implementation of the interface:
[AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]
Then in the service webconfig I have this (parens are angle brackets):
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
<add prefix=[URL]>>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
Then in the client side I attempted this:
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
<compositeScript>
<Scripts>
<asp:ScriptReference
Path=[URL]/>
</Scripts>
</CompositeScript>
</asp:ScriptManagerProxy>
I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc.... I am willing to make any changes.

I have this method in asp.net ajax enabled mvc service
[OperationContract]
public TestRun GetTestSuite(string testSuitName) {
TestRun testRun =
AdapterFactory.CreateTestRunAdapter().GetByTestSuiteName("testSuit");
return testRun;
}
Where TestRun is Created using entities framework against TestRun table. I am using following ajax method
function getTestSuite() {
$.ajax({
type: "POST",
url: "Services/TestRunService.svc/GetTestSuite",
data: '{"testSuitName" : "' + testSuiteName + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
},
//If the call fails
error: function (xhr, textStatus, errorThrown) {
alert(errorThrown);
}
})
}
I get undefined error. If I return string from service it works. Do I need to change dataType: "json" to something else?

I have a web service with the following contract:
POST /Service/service.asmx HTTP/1.1
Host: xxx.xxx.xxx
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "xxx.xxx.xxx/Service/Method"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<Request xmlns="xxx.xxx.xxx/Service/">
<transactiontype>string</transactiontype>
<username>string</username>
<password>string</password>
</Request>
</soap:Header>
<soap:Body>
<Method xmlns="xxx.xxx.xxx/Service/">
<xml>xml</xml>
</Method>
</soap:Body>
</soap:Envelope>
And I am trying to call the service using jquery. This is my code:
$.ajax({
url: serverUrl + 'Method',
type: "POST",
dataType: "xml",
data: { xml: "xml" },
beforeSend: function (req) {
req.setRequestHeader('Header', '<Request xmlns="xxx.xxx.xxx/Service/">'
+'<transactiontype>4</transactiontype>'
+'<agencyName>name</agencyName>'
+'<username>user</username>'
+'<password>pass</password>'
+'</Request>');
},
success: function (data) {
alert(data.text);
},
error: function (request, status, errorThrown) {
alert(status);
}
});
However, the header content is not passed to the web service? How would I go about passing the header credentials to my web service call?

When I was reading the blog Using jQuery to Consume ASP.NET JSON Web Services
I have seen this argument:
"By using jQuery to call the web service directly, we've eliminated over 100 KB of JavaScript and three extra HTTP requests. "
Why does the ASP.NET AJAX call to a .NET Web-Service needs 3 extra HTTP requests? What are those requests? (I wonder how jQuery manages the call with lesser HTTP requests in this case).

I have a simple web service that isn't working with a standard jQuery call. The code is below. The jQuery will execute and succeed, but on debugging, the service argument is always null. I've had it separated as 4 string params in a json string and that didn't work either. I must be missing something on the config side, but I can tell what it is.

i'm new to asp.net MVC, and I'm trying to understand the service/repository pattern and how to best implement it.
I've followed the MVC Music store tutorial, and it suggests that the public partial class ShoppingCart implements an AddToCart method looking like this:
[Code]....
Now if I would like to use the service/repository pattern in a correct way, should I just replace the row "storeDB.AddToCarts(cartItem)" with something like cartService.AddToCarts(cartItem) and then just save the added row by calling cartService.Save() instead of shopDB.Save()? The methods AddToCart(...) and Save() in cartService then calls the repository that does the actual saving.

I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Public Class CustomValidate
Inherits System.Web.Services.WebService
'ACCESS VIA JSON
<System.Web.Services.WebMethod()> _
Public Shared Function AJAX_Test(ByVal date1) As Boolean...
Return True
End Function
End Class
Javascript: JQuery JSON
function isDates(source, arguments) {
var isValidDate;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CustomValidate.asmx/AJAX_Test",
data: '{date1: "' + arguments.Value + '"}',
dataType: "json",
async: false,
success: function(result) {
isValidDate = result;
},
error: function(httpRequest, textStatus, errorThrown) {
alert("status=" + textStatus + ",error=" + errorThrown);
}
});
arguments.IsValid = isValidDate;
}
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.

Firstly - I'm not asking this question How to include a web service in MVC3? I know where the button is :-)
I'm trying to find an example of best practices of how to use the new DI / Common Service Locator framework in order to make web service calls (and code dependent on web service calls) testable. I've no experience of using NInject or the like - is that the way to go?

When I first heard about ASP.NET MVC, I was thinking that would mean applications with three parts: model, view, and controller.
Then I read NerdDinner and learned the ways of repositories and view-models. Next, I read this tutorial and soon became sold on the virtues of a service layer. Finally, I read the Fluent Validation documentation, and I'll be darned if I didn't end up writing a bunch of validators.
Tonight, I took a step back and thought about what had become of my project. It seems to have become the victim of the design pattern equivalent of "feature creep". Somehow I'd gone from Model-View-Controller to Model-Repository-Service-Validator-View-ViewModel-Controller. You want loosely coupled and DRY? We got your loosely coupled and DRY right here! But I'm wondering if this could be a case of too much of a good thing.
Am I right to be concerned? Or is this actually not as crazy as it sounds? On one hand, it seems crazy to have so many layers. On the other hand, every layer has a clearly defined purpose that makes sense to me. Have your MVC applications turned into MRSVVVMC apps too? If not, what do they look like? Where's that right balance?

We have an ASP.NET MVC site that uses Entity Framework abstractions with Repository and UnitOfWork patterns. What I'm wondering is how others have implemented navigation of complex object graphs with these patterns. Let me give an example from one of our controllers:
[code]....
It's a registration process and pretty much everything hangs off the POCO class Person. In this case we're caching the person through the registration process. I've now started implementing the latter part of the registration process which requires access to data deeper in the object graph. Specifically DPA data which hangs off Legal inside Country.
The code above is just mapping out the model information into a simpler format for the ViewModel. My question is do you consider this fairly deep navigation of the graph good practice or would you abstract out the retrieval of the objects further down the graph into repositories?

Does anyone have a working pattern for converting a GET-POST-GET pattern to asny?
I'm encountering the following issues:
1. You cannot mix Sync and Async action methods SubmitForm(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() ... (because the resolver gets all confused ... it doesn't use the HTTP verb to decide who to target. BTW: I think that's poor design, or a bug)
2. Renaming the get method name to something else eg: SubmitFormConfirmation(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() would be very awkward if it works ... because you have to doctor the <form markup to specify an action name.
3. You cannot give them all async names SubmitFormAsync(), SubmitFormAsync(bool? confirm), submitFormCompleted(), because the call just keeps malfunctioning. It sometime even behaves as if you are requesting a delete of something.
Can someone give an insight from an actually working sample.
