Passing Custom Object As Parameter To A Webmethod Of Web Service?
May 11, 2010
I have a custom class declared as follows (in vb.net)
<Serializable()> _ Public
Class NumInfo Public n As String
Public f As Integer Public fc As
char() Public t As Integer
[Code]....
What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button.

I have a custom class declared as follows (in vb.net)
<Serializable()> _
Public Class NumInfo
Public n As String
Public f As Integer
Public fc As char()
Public t As Integer
Public tc As char()
Private validFlag As Boolean = True
Public Sub New()
End Sub
I also have public properties(read/write) for all the public variables
End Class
In my service.asmx codebehind class I have a webmethod as follows:
<WebMethod> _
<XmlInclude(GetType(NumInfo))>
Public Function ConvertTo(ByVal info As NumInfo) As String
Return mbc(info)
'mbc is another function defined in my service.asmx "service" class
End Function
The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:
ConvertTo
Test
The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.
POST /BaseConverter/BaseCon.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://RohitServices.in/ConvertTo"
<?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:Body>
<ConvertTo xmlns="http://RohitServices.in/">
<info>
<n>string</n>
<f>int</f>
<fc>
<char>char</char>
<char>char</char>
</fc>

I just can't seem to get it working with custom object.

I am calling a WebMethod from this code:
if($(this).attr("checked")) {
..
MyWebMethod(variable1, variable2, onSuccessFunction);
}
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
MyWebMethod(variable1, variable2, onSuccessFunction($(this)));
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?

Recently, I tried to get my Web Service class to inherit from a custom base class that inherits from System.Web.Services.WebMethod instead of the System.Web.Services.WebMethod directly.
However, I've been getting Error 500.
Public Class Service1
Inherits BaseClass
<System.Web.Services.WebMethod()> _
Public Function GetSessionID() As String
GetSessionID = Me.Session.SessionID
End Function
End Class
public class BaseClass
Inherits System.Web.Services.WebService
public property Property1 as string
public property Property2 as string
End Class

I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?

I've implemented a custom ASP.net membership provider to deal with forms authentication. The custom provider uses a custom User object for authentication and authorization. I was wondering If I can pass this object to each WCF call without adding it to the parameters list?

We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.
The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

I'm kinda new to web services and want to make sure I am doing things correctly.
I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)
I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?
What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.
I tried this dll
[URL]
But the output XML doesn't seem to include the sub object.

Is there a way to retrieving parameter names and values passed to a web method from Request object? I've read somewhere that you need extra code to access the soap body. Any known workarounds to be able to see the soap body from Application_BeginRequest?

I've a problem: I've a GridView, with a folder structure, and an asp.net checkbox for each row in the gridview.Now, when the user clicks the delete button, it should delete all the folder entities where the user checked the checkbox.The problem is, there may not be a postback...So I used to use findcontrol in an ordinary asp.net button codebehind, but in a webmethod, it's impossible to access the page object, because WebMethods need to be static...Now I tried ctype(httprequest.current.request.handler,page) but that doesn't seem to work...
How can I get the page object to use findcontrol ?

I tried your code for Autocomplete without Webservice and didn't work on my page. When I tried it on a new project it works fine but on my project it does not. I have other controls on the page but that shouldn't stop it from working right?

I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?
