js:
[code]....
I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
I´m using jQuery to make the ajax calls to web services. I´m not using json, I want the information in XML. If I don´t pass parameters and I make the WS parameter less it works but if I want to pass a value as parameter (I tried int and string) it doesn´t work. Here is my code:

The error that I get from firebug is an exception System.InvalidOperationException and it says that the parameter region_id is missing.It can´t be very difficult because it works without parameters but all the information I find in internet
I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file):

Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:ProjectsSamplesmytestwebsite'".
I am trying to call web service from jquery..trying following way but i am not able to pass to complex type parameter to WCF service.My wcf function is as follows
<OperationContract()>
<Web.WebGet(UriTemplate:="/GetData?strErrMsg={strErrMsg}&chrErrFlg={chrErrFlg}", ResponseFormat:=WebMessageFormat.Json, BodyStyle:=WebMessageBodyStyle.Wrapped)> _
Function GetData(ByRef strErrMsg As System.Collections.Generic.List(Of String), ByRef chrErrFlg As String) As String
strErrMsg is System.Collections.Generic.List(Of String)
I am trying to call as follows
var Type;
var Url;
var Data;
var ContentType;
var DataType;
var ProcessData;
var parameters;
[code]...
And I am able to call other methods in same way having string and integer parameter.I have gone through this but didnt get anything. URL...
I have a simple Web Service method defined as:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string MyWebMethod(string foo, string bar)
{
// DataContractJsonSerializer to deserialize foo and bar to
// their respective FooClass and BarClass objects.
return "{"Message":"Everything is a-ok!"}";
}
I'll call it from the client via:
var myParams = { "foo":{"name":"Bob Smith", "age":50},"bar":{"color":"blue","size":"large","quantity":2} };
$.ajax({
type: 'POST',
url: 'https://mydomain.com/WebServices/TestSvc.asmx/MyWebMethod',
data: JSON.stringify(myParams),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (response, status) {
alert('Yay!');
},
error: function (xhr, err) {
alert('Boo-urns!');
}
});
However, this yields the following error (a breakpoint on the first line in MyWebMethod() is never hit):
{"Message":"No parameterless

I'd like to pass in two string parameters and use DataContractJsonSerializer to write new Foo and Bar objects. Am I missing something?
I want to develop a windows service which will be accepting a datatable from an aspx page. Both the windows service and the website are hosted on same machine.
Also I need to set a date and time on which this service is to work. this date and time are to change according to customer needs. once again the date and time are to be fed from the aspx page.
I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array.
Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough,
I'm trying to do a form submit to my controller through jQuery Ajax. The following code works for the most part, however, the ThreadId parameter does not get passed. If I call the controller directly without using jQuery, it gets passed, but when using jquery, I don't see the ThreadId after form.serialize(). WHat would be the easiest way to pass parameters (like ThreadId) to jQuery form post?
[code]....
Basically we have a web service that the client uses to get all sorts of information, works well. Now I would like the client to call our web service, and for us to update our database based on the information getting passed (just a bool, and time).This will be used to determine what stage the client is at (they do QA). Is this possible?
View 1 RepliesI 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?
I have used a sql data source to connect to ORACLE.
Select command is working fine, as soon as I try to provide a parameter, it doesn;t work.
Getting following error " ORA-01036: illegal variable name/number"
Tried searching for error message -- but It says the parameters name has to be less then 32 characters, which is what I have.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DevConnection %>"
ProviderName="<%$ ConnectionStrings:DevConnection.ProviderName %>" SelectCommand="Select ID, Name from Employee where state = @stateid">
<SelectParameters>

I have a modal popup that displays detail info based on a grid view selection. The SELECT requires a id and a year. The year is displayed in a drop downon the main page and the popup seems to be able to read it OK. BUt the ID is part of the grid view and I am not usre how to pass it to the popup.
[Code]....
I thought that I would set theID in the lnkRank_Click event, but the code seemd to pop the modal without ever going to that event.
[Code]....
I can set a debug break on this method and it never hits it. So, somehow clicking the image button does trigger the popup but does not set the text field to the desired ID. How is this supposed to work?
I have a page with a partialview on it which is a list of items. I have a button on it which shows the next 5 items.
This is done via ajax:-

How do I keep track of that variable?

I have site that I need to have a vendor send an Http Post to us, using querystring parameters, then I have to look up some data and return a few results and parameters back to them. Can this be done using CLASSIC ASP? I ask this because I am still in a learning phase with .NET and have limited resources available to set up a web service.
View 2 RepliesI am using JavaScript to call a web service. The JS is correctly receiving and passing the web service information.
At the moment, the web service returns a country name as a string to a JavaScript alert pop up box as follows:

I want to change this so that web service returns the country name to a label inside an insert item template of a form view.
Is there a way to pass in the label variable to the OnComplete function signature and still account for the variable args?, such as:

I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.
JavaScript Code:
$.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) {Â Â console.log(msg.d);}});
C# Code:
[WebMethod]public static object GetStuff(string a, int b){Â }
Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.
I am currently using this example [URL]. I am getting errors adding an additional parameter to the data portion.
I want to add this
var value = $("#Hidden1").val();
to this
$.ajax({
type: 'POST',
url: '/Sortable.asmx/UpdateItemsOrder',
data: '{itemOrder: '' + order + ''}',
contentType: 'application/json; charset=utf-8',

I have Two Forms StringMain.aspx & Returner.aspx.... I have created 4 Divs at StringMain.aspx and a sample text "ToCheck" at First Div.. In the Returner.aspx form page load, i placed a label like this
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = "hello";
}
I have set StringMain.aspx as default running page. So When i run StringMain.Aspx page,
the text i placed in the First Div "To Check" should concat with the label Text "hello" of Returner.aspx and display it together in the First Div of StringMain.aspx like this
"To Check hello"..
The Technique i used is
$("div#First-Div").load(" Returner.aspx");--But dint work...
I would like to pass the content from a multiline textbox into an sql database using jQuery .ajax.
function UpdateMemogramContent() {
$.ajax({
type: "POST",
url: "MemogramWebServices.asmx/UpdateMemogramContent",

contentType: "application/json; charset=utf-8",
dataType: "json",
success: Success,
error: Error
});
}
The problem I am facing is that the content from the multiline textbox is throwing an invalid json primitive exception. Taking a look at the POST:
{ 'mId': 314, 'content': Test
Test}
What can I do to pass the text from a multiline textbox into an sql database using .ajax?

I'm building a greasemonkey script to make posting to craigslist a lot easier for our clients.
Basically the flow is this:
User logs into our system (established authentication cookies with asp.net)User navigates to a section on our site called "CraigsList". If they have the greasemonkey script installed it automatically opens up craigslist in a new tab.
The greasemonkey script then does a request back to our site at [URL] to retrieve a list of available items to be posted to craigslist.
This is where it fails because the request to [URL] is not including any of the authentication cookies. I'm not sure if it doesn't include the cookies because the request originates from [URL] and not [URL] or what. I know it's an authentication issue because looking at it in fiddler it returns a 302 and redirects to the login page.
Here is my request:
