JSON Data Cannot Be Matched To Web Service Signature?
Sep 1, 2010
I still can't seem to get this to work.I've tried string arrays object arrays dictionaries. I might be formatting my JSON incorrectly however I am using the labs_JSON plugin. If I remove my data and test the webservice it calls correctly. The : My code looks as follows :
HTML :
<div style="display: block; float: left;">
<asp:Repeater ID="rptMenuRecipeCategories" runat="server">
<HeaderTemplate>
<div class="recipeChecklistHeader">Menu Recipe Categories</div>
[Code]....

I have never write code like this... so I am trying to explian what problem I meet here..
assuming I have 2 web service
one named WS1 another named WS2
WS1 (send data to WS2) → WS2 then WS2 (receive data from WS1 and do something then return result to WS1)→WS1
if I want to add digital signature between WS1 and WS2 so that WS1 connecting to WS2 , WS2 will recognize who is connecting by digital signature
what do I need if I want to do that? and how to do?

I have a web control with a text box configured like this:
[Code]....
I am unable to get it to hit the method in my service with a signature like:
public
string[] GetOrganizationNames(string searchText,
int count)
but it does get to the method if I change the signature to:
public
string[] GetOrganizationNames()
For obvious reasons the second one will not do me any good. I have verified the data coming back from the method is good.

I'd like to read data server-side from a web service that outputs in json format. I haven't found any good examples that don't use jquery and are server-side.
Specifically I'm looking at the "weight" field from this api:

Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.

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.

We have a web application providing a service using a simple REST interface (GET/POST methods) and returning results in JSON format.
A client wants to use the service from an ASP application (I assume ASP.NET) and asks for example code.
Is there any standard/widely-acceptable procedure for consuming JSON based web services from an ASP.NET application? I'm not familiar with the .NET framework, but can work my way through C#.

What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view)

I have developed a wcf service for asp.net ajax client. It includes the following steps.
(1) Created WCF sevice contract with the operation "DoWork()" which will take string as input and retun string as output.
(2)Implemented the above operation contract(attributed the implementation class with aspnetcompatibility requirement as enabled).
(3)Added the webscriptenabled to endpoint in web.config file.
(4)Hosted the wcf servie.
(5)Downloaded the javascript file from the service.(e.g.,http://localhost/service1.svc/js)
Client
(1)Opend new asp.net webapplication.
(2)Added the downloaded .js file.
(3)Given the scripts path for ajaxscript manager as both .js file and service url.
e.g
<asp:ScriptManager
ID="id1"
runat="server">
<Scripts>
<asp:ScriptReference
Path="http://localhost:3443/Service1.svc/js/"

I have an containing a list of divs that jQuery turns into progress bars. On .ready, I build a list of all of these progress bars and for each one, call a webservice that gets a value indicating how full the progress bar should be. In order to do this, I need to pass the ID of the div to the web service.
Because the divs are inside a ListView, I manually set the id to be id="completionbar_<%# Eval("MilestoneID") %>"
However, when I pass this id into my web service, it comes up as "undefined" every time. When I view the source, it looks like it's set correctly.
Here's the jQuery that calls my web service:
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$(".MilestoneCompletion").progressbar({ value: 0 });
$.each($(".MilestoneCompletion"), function(index, barDiv) {
[Code].....
I'm thinking maybe the script is executing before the DIV id is set by the ListView databind?

As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) {
var row = results.rows.item(i);
var customer = new Object();
customer.id = row['id']
customer.name = row['name']
var customerString = JSON.stringify(customer);
$.ajax({
type: "POST",
url: "synchronise.asmx/synchroniseCustomers",
data: "synchroniseCustomers: " + customerString,
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status) {
alert("An error occurred: " + status);
},
success: function (msg) {
alert("success");
}
});
}
WebMethod:
public void synchroniseCustomers(string customerString)
{
JObject o = JObject.Parse(customerString);
string id = (string)o["id"];
string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.

I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person
I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.
Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.

I am using Compute for summing up a datatable which has a condition. Sometimes, there are no rows inside the datatable matching my criteria so I get an exception on ComputeObject cannot be cast from DBNull to other types.Is there a way to check/filter the datatable to see if it has the desired rows, if yes only then I apply Compute.
total = Convert.ToDecimal(CompTab.Compute("SUM(Share)", "IsRep=0"));
