MVC :: Call A Service Operation Of Wcfdataservice From A Controller?
Dec 10, 2010
I did some service operation in mywcfdataservice.svc Now I have to use the service operation in my controller but I don't find them.I can use:
Entities2Voice context = new Entities2Voice();
and so I can read the table of my db, but I didn't find the way to see sevice operation.I have my model.edmx to use sql db and the code in mywcfdataservice.svc works right. I can call the service operations from my browser and they work.I try to add service reference to my .svc file, to use it as a service, but when I press ok button after some seconds, I take an error (is in Italian):Il documento HTML non contiene informazioni per l'individuazione del servizio Web.I metadati contengono un riferimento che non può essere risolto: 'http://localhost:2873/WcfDataService2Voice.svc'.Il tipo di contenuto text/html; charset=utf-8 del messaggio di risposta non corrisponde al tipo di contenuto del binding (application/soap+xml; charset=utf-8). Se si utilizza un codificatore standard, verificare che il metodo IsContentTypeSupported sia implementato
correttamente. I primi 1024 byte della risposta erano: '
I have an asp.net MVC2 application that needs to call a web service from the controller. How do I do this? It is a RESTful service that returns Json data.
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
I am receiving System.Security.VerificationException. {"Operation could destabilize the runtime."} Asp.net mvc 3 + Razor rc1 and rc2 and NUnit and MoQ.
After some research, I did see that similar error with TypeMock but it was fixed with Microsoft .
When an ASPX page needs to make a call to a potentially long-running operation (lengthy DB query, call to a remote webservice, etc.), I use RegisterAsyncTask, so the IIS worker thread is returned to the pool, rather than being tied up for the duration of the long-running operation. However ASMX webservices don't have a RegisterAsyncTask function. When an ASMX webservice needs to call a potentially long-running operation, how can I implement the same behavior as RegisterAsyncTask? Note: the ASMX webservice is implemented as a script-service: returning json to a direct jQuery/ajax call. Therefore, I cannot use the "BeginXXX" approach described by MSDN, since that implements the asynchronous behavior within the generated client-stub (which isn't used when calling the webservice directly via ajax). EDIT: Adding source code: implemented the BeginXXX/EndXXX approach listed in John's answer. The synchronous "Parrot" function works fine. But the asynchronous "SlowParrot" function gives an internal server error: "Unknown web method SlowParrot"
How to call Synchronous service call for combo boxes? As I know Synchronous calls do not create a good user experience because the application is hung waiting for the Web service call to return. Then it is my requirement.
i have created a normal web service and i want to host it outside IIS. one idea i got is to use window service as hosting environment. i have created a web service and hosted it window service and its window service is running now.would anybody please let me know that how can i call web service hosted in window service binded over soap.tcp. here is my sample code.
I have one problem with actionlink. My Example is: i have one view and controller named as XYZ.aspx and XYZ.vb controller , in this view i put below line
<%=Html.ActionLink("Manage", "Index", "Advertisement", New With {.aintCampaignid = Cam.CampaignID})%>
I have another view and controller named as Index.aspx and Advertisement.vb if click on manage link in XYZ view it will call to advertisement controller and index function But iam getting [URL], it wont call ..
application has a main controller which gets some requests that should be filtered first. This main controller decides which other controller should handle the request.The redirection is usually possible with RedirectToAction(..). But using this method causes a round trip and changes the original called url. This behaviour is not wanted. The url should e left as it was in the origin request.Is this possible? If yes - how?If i instanciate a controller myself (simple call of new MyConstructor()) and call the wanted action then this controller runs in the wrong context and the views won't be found.
Can I call a webservice from a Controller Action in ASP.Net MVC?
public ActionResult Index() { PersonObject person = new Person("Sam"); //Call a webservice which is located in the same app under /Services/General.asmx/WebMethod and pass it person }
I'm working on getting a new MVC 3.0 application up and running on a Windows 2008 server, running SQL05 and IIS7 with ASP.NET Framwork 4.0 as well as MVC installed. The index page has two select boxes. Selecting an option in the first select box does an ajax call to my controller that populatest the second select box. This works just fine on my winxp dev machine but returns a 404 on the call to the controller when running on the server. Code for that call:
<% Html.EnableClientValidation(); %> <% using (Html.BeginForm("CamperDirectory", "TradingPost")) { %> Select a Season: <%: Html.DropDownListFor(x => x.SelectedSeason, new SelectList(Model.GetSeasons, "Value", "Text"),"Please select a Season.") %><br /><br /> <%: Html.ValidationMessageFor(model => model.SelectedSeason)%> Select a Session: <%: Html.DropDownListFor(y => y.SelectedSession, new SelectList(Model.GetSessions, "Value", "Text"), "Please select a Summercamp Session.") %> <%: Html.ValidationMessageFor(model => model.SelectedSession)%> <input type="submit" value="Go" /> <% } %> </asp:Content> <asp:content ID="Content3" contentplaceholderid="HeadContent" runat="server"> <script language="javascript" type="text/javascript">...............................

As I call the Controller to exit the focus of my textbox? I need to exit the textbox, go to the database to get information that will supplement the information from my form.
I have a mvc controller that communicates with a we service for user authentication, when user clicks login button, onclick event makes a call to javascript function using ajax and it makes a call to an action in server.The problem is when a use fiddler tool shows ajax call to the controller and also web service call, web service is called from controller never javascrit, how I can protect visibility of web service calling?, using web forms with the same scenario never shows a web service call.
These types of exceptions always irritate me because they are almost impossible to reproduce consistently and have almost no documentation other than the cryptic error itself to have any idea on how to fix the problem. So I have a Windows Service that makes a call to a .asmx web service over https on a polled interval every 20 minutes. Once in a great while the following exception message is returned:
Message: The underlying connection was closed: An unexpected error occurred on a receive.
Inner Message: System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception:
The specified data could not be decrypted --- End of inner exception stack trace --- at System.Net.Security._SslStream.ProcessReadErrorCode(SecurityStatus errorCode, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest, Byte[] extraBuffer) at System.Net.Security._SslStream.ProcessFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)
So from reading the above message there was an error on receive and the data could not be decrypted. The does not occur consistently, so I don't have a good way of reproducing it. I also lack at low level messaging knowledge and I feel that this is the answer behind this exception; i.e. dropped packets and an incomplete message not appearing to be the same message as sent from the service or something. Any .asmx gurus out there that can give insight and possibly prevention suggestions for the above issue?
This is probably something simple. The following JQuery call is executing and calling the controller. The controller is executing correctly. I used the sample data that's commented out to verify that the templates were working also. However, the success function is not executing in the browser. Any thoughts or other ways I can debug this?
Also I have a dropdownlist, how do I call the controller's action after I click the "Submit" button?
And how do I pass the Model back to the controller action as well?
The reason I want to pass back the model (or other object/class) to controller's action is I might have 5 dropdown lists and 3 edit boxes values to be sent as parameters. So I would like to assign these parameters into a object and send it back to controller's action.
ia ma working on an asp.net mvc 2 app and i have a Users view, displaying all the users of the database. Then, i would like to add the ablility to display "users starting with fisrt name" capabaility on the same view. For this i created a list of all english leters that actually are links (<a href="#">A</a>, etc...)
I managed to handle the click event of each one of the letters and get the corresponding letter via jquery, but i don't know how to call theHttp.Post Users/FindUserByFirstLetterName(string letter) on the click event.
I cannot use the Html.ActionLink<> helper, since it redirects me to the HttpGet controller action.
I also tried using using jqery.Post but i also couldn't manage to call the action.
i would like to call an HttpGet GetEvents(Datetime dateSelected) controller action each time the user cliks on a date in jquery ui datepicker. I handle the onSelect datepicker event in order to call GetEvents() and refresh the Events page with the events for the selected date. The $.ajax method i use from jquery hits the GetEvents action, but instead of refreshing the page (and the url), i get an ajax result back.
[Code]....
So, how could i just call the HttpGet GetEvents() controller action via jquery, without the use of ajax in order to refresh the page?
