I am developing an application with WCF services. The basic functionaloty of a screen is to provide an entry screen to add particular entity. Once save even fired It will save the data to the database and call the bind method to bind into the grid by refreshing the latest data.
When I am running the site from my source (Visual Studio) , it works perfectly. When the client calls method to fetch the data the WCF service, it returns latest (added) data. But the issue comes in the server when it works with IIS. I deployed the code in the server, once the data added I am getting the old data only. But after two refresh I am getting the latest data.
what required to be done to get the latest record.

I've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?
View 1 RepliesWould it be better in terms of payload, if I return a datatable as a List<DataRow> from a WCF method? I have WsHtppBinding for my WCF. I am expecting the datatable to contain 5,000 to 10,000 records.
Also, how can I test the difference in payload sizes when returning a DataTable Vs List<DataRow>?
I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.
I want to create a web method that accepts a List of custom objects (passed in via jQuery/JSON). When I run the website locally everything seems to work. jQuery and ASP.NET and everyone is happy. But when I put it on one of our servers it blows up. jQuery gets a 500 error after the ajax request with the response being:
System.InvalidOperationException: EditCustomObjects Web Service method name is not valid.
[WebMethod]
public void EditCustomObjects(int ID, List<CustomObject> CustomObjectList)

I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
In my WCF service i exposed two services service1 and service2 now consumer/client do not intrest to consume service2 then how he will restrict this?
View 1 RepliesI added a Web Method to the existing web service. I don't see this method in my web project. I can see all the old methods but I couldn't access this method. Do I have to create proxy for this method?

View 2 Replieswe need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.
View 4 RepliesFor example, we are going to consume web method GetEmployeeByQuery(ConnInfoXML, Query, RecordDetail), ConnInfoXML is login information in XML, Query is a SQL statement selecting records, RecordDetail is all records retrieved. All data are in XML format.
So how to write these parameters in XML to consume this web method and get all the information in XML, and then transfer XML to normal string format ?
I have a web service called service1. Is it possible to pass the parameter related to the service to a class library so for e.g.
Service1.service ws = new Service1.service();
Service1.UserDetails ud = null;
now if I call a method that exists in a class and pass ud. Cam i do that because I am trying to do this and I am getting an error. Do i need to add a web
reference to this service in the class library My method call is like this
authenticateUser.Authenticate(ud, UserName);
and in the class libary I have
public void Authenticate( Service1.UserDetails ud , string UserName)
{
}
I would like to pass xml document to a method in WCF service by client that server will get xmldocument,parse it and send back the xml response.What are best practice for thi?The xml document is conform to XSD so i would like to create managed type that represent the schema and then expose thatIf anybody has done it before or know any example please point it out so i can see it.

I have a web service that has a CreateReport method that generates a report based on the specified criteria.
When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.
When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.
When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.
I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.
I need to pass a random number from 1 to 100 from the client to a webservice, and then the webservice will subtract this number from the list of 100 numbers (say 1-100). Then, in the next call, the next random number will be subtracted from the rest 99 numbers and so on.
I need this to be done with AJAX. I don't know where the Array list should be held in the first place (would it be in the web service or in the code behind? ), and how this can be done?
My web services have base web service method called IsGood()I want to make sure every methods in my web service call IsGood() in base web service automatically without add code in each web service method, can I do that?
View 2 RepliesI 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.
