How To Expose Custom Object (with Sub Objects) In Web Service
Feb 11, 2010
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.
What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:
[AcceptVerbs(HttpVerbs.Post)] public ActionResult Details(VideoDetailModel vidAndComment) { ....} [Code]....
The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.
public class VideoDetailModel { public VideoDetailModel() { [Code].... I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.
For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.
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?
[WebMethod] [SoapHeader("_webServiceAuth")] public User GetUser(string username){ try { this._validationMethods.Validate(_webServiceAuth); User user = new User(username); [code]...
We've got some WCF services we're hosting via IIS. The application in general uses Forms Authentication, and we'd like to continue making that available for web service clients. We just have a <authorization><deny users="?"> in our web.config and some authentication/redirection goodness that gets everything done.
The problem is we'd like for users to be able to access the metadata for the services without authentication. Can they visit /services/v1/ArtifactService.svc?wsdl anonymously and yet still require authentication for /services/v1/ArtifactService.svc/rest/GetArtifacts?studyId=123? If so, I can't figure out the right incantation in the configuration.
The best I can think of is to set an absolute URL in the metadata service behavior, but then I have to doctor the path on install anywhere we deploy. (<serviceMetadata httpGetEnabled="true" httpGetUrl=[URL]
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>
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 just can't seem to get it working with custom object.

I created a simple gridview user control with a custom property ProfileType which should load different records depending on the ProfileType value when attaching to a web page.
This is my web page:
[code]....
how I can expose user control custom property at its code-behind file.
I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).
With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.
What am I doing wrong?
UPDATE
I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.
The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.
Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.
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'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?
I have an existing web application that uses EF and POCO objects. I want to improve the client experience by exposing some of my objects through WCF(JSON). I have this working fine but where I am unsure is how to handle derived objects(not sure if that is the correct term) or IEnumerable anonymous objects if you will.
Let's say I have 3 tables structured like so:
Templates
ID Template
Groups
ID Group
Instances
ID TemplateID GroupID
This is obviously a one-to-many type relationship. I have my navigation properties setup correctly and getting strongly typed object properties works great. However, how do I send serialized anonymous type object(s) over the wire. Like an object that sends all instances that are equal to groupid=1 and include the names of the template and the object.Am I missing something or do I have to create another class object for WCF that would look like this:
I guess I could alter my tables to account for this but that seems wrong too. I know that IEnumerable objects can't be serialized and I know that throw away objects are probably not the way to go either. I want to do this the right way but I am not sure how to go about it.
I could really use some help on this one. I've been fighting it now for several days and we are supposed to start testing early next week.I am subscribing to 4 web services all hosted by the same company. The integration with 1, 2 and 3 all went fine, but on the fourth I keep getting the very unhelpful error:
System.Web.Services.Protocols.SoapException = {"Server was unable to process request. ---> Object reference not set to an instance of an object."} [code]...
How to use $.ajax(..) JSON to invoke asmx webmethods that have 'by ref arguments' for custom classes/objects? Is it possible?
My c# code - public class MyCustomClass{ public int MyProperty; MyCustomClass(){}} [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public Method1(ref MyCustomClass MyCustomObj)
[code]...
This all works fine if the webmethod's argument is NOT by ref.With the above mentioned signature of the webmethod, i.e. with a by ref argument, I get a server error (in server response seen using firebub ) -
I found some code on the web and it threw me off. Look at the code below. You will notice only when the Hits == 1, does the cache get added. After that, the cache object isn't updated. It begs the question, does the object when updated, update the cache as well automatically? The answer here would make me remove some code in some of my classes.
We have an asp.net web service running on Windows Small Business Server 2008 SP2 (64-bit). It is in its own application pool. We've tried both Integrated and Classic settings for Managed Pipeline Mode. Enable 32-bit Applications is set to True. It is not able to successfully call a vb6 dll method but a Windows Forms app on the same machine can.Two vb6 dlls (A and B) are instantiated. The method in A is passed a reference to B as one of its parameters. That method then calls other methods within itself that also require the reference to B.Those internal method calls in A fail with this vb6 error (the A method logs these errors in the Windows Application event log):
70 (Permission Denied)
Another error is also logged in the Windows System event log:
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {xxx} to the user NT AUTHORITYNETWORK SERVICE SID (S-1-5-20) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.The object in question (a third vb6 component which is an ActiveX EXE) has already been configured using DCOMCNFG (Component Services) with full Launch, Activation, and Access Permissions given to NETWORK SERVICE and even Everyone. Additionally, from Explorer, full control/permissions have been give to all required vb6 components to NETWORK SERVICE (tried Everyone too).
A Windows Forms application on the same machine is able to successfully call the method in A. The same web service works on another machine with a 32-bit OS.Both the web service and the Forms app have been built with Platform Target set to "x86".How can we get the web service call to work on the 64-bit machine?
How can I add custom properties into control objects in ExtJs.
For example :
[code]....
This control comes from server dynamically and I want to write my custom property as well like below :
[code]....
I tried it but it said undefined. Normally since JavaScript is loose, I can easily modify objects but in this case it wouldn't work the way I expected.
I have a model containing a List with custom objects, let's say Customer objects. Like this:
[Code]....
In the View I print out (for simplicity) the name and id of the customer objects on the model. How to restore these values on postback if the method signature looks like this:
[Code]....
Should I use hidden values? This is not possible if the List contains items of interface type, for example List<ICustomer> where ICustomer is an interface. Is there any other way to "save" the values on each postback? For example I may want to view validation error messages when the user submits the form and then the properties of the customer object must still be there..
I used Object Test Bench to test my classes in VS 2008 professional edition . Right click on Class name and then selected create instance ,then its Constructor, there comes a dialog box, that just gives a message and a TextBox field is present there, i filled that field with any name and clicked OK.Then error message comes that "Create Instance Failed" and its error code is "0x80004005" . What's this ? How to instantiate object of my classes ?
But with the same procedure i can create object in WPF applications. What is problem with asp.net ?
I want to access membership and profile objects and wants to access profile properties that I have defined in my web app web.config file, from a windows service. Anyone have any idea on how to do this?
