MVC :: Set Up A Controller Method Do Read A GET Request?
May 26, 2010
I am having trouble finding any information on this but basically in MVC how do I set up a controller method do read a GET request? For example I have the following url,
I have a controller method that returns a jSON object and in one calling situation, it works and in another calling situation, it does not work. When the URL in my browser is this:
http://localhost:65247/Client -- it works.
But, when my url looks like this:
http://localhost:65247/Client/UserAdmin?id=6 -- it DOES NOT work
In a nutshell, clients have users. From within the client, I wish to work on a specific user (this is the UserAdmin view). In this case, the client id is 6. From within the UserAdmin view that was launched with Id=6, I then wish to select a user from a dropdown. The idea was to use javascript and $.getJSON to fetch data for the specific user so as not to have to refresh the entire page. I use this approach in other parts of the app. The only difference I can see is with the URL in the browser. It would appear the presence of parameters via the '?' is futzing things up a bit.
When I use editurl property in my jqgrid, the controller action gets called after I hit submit button on adding a new row. But how do I get all the grid rows there? Which parameter should I read from my controller action method in order to get the grid data?
How can i transfer control to a controller's method from a controller's method..I am having two Controllers Home and User.. After username and password are verified inHome Controllers method , i want to show the User Controllers index page , so i have to callindex method of Home controller..How can i do it.
I've noticed that a request to 'favicon.ico' is being passed to my ASP.net MVC controller factory when using Google Chrome and the Visual Studio Development Server. The 'controllerType' parameter has a value of 'null' which is unsurprisingly resulting in an unhandled exception and which I only know about because of an error log.where the request is coming from and why ASP.net is letting it get to the controller factory? CSS files and images for example are being correctly filtered out.
I have a requirement whereby I need to be able to change the controller being used based upon a parameter. I am creating an application that needs to be dynamic enough to be able to change controllers on the fly. Let me explain further;
When the application starts a dictionary of custom controller names is loaded with a controller name as the key and a custom controller name as the value. This will be help in the application scope.
When a request is made I need to access the requested controller name, use that name and check to see if it matches a key in my controller dictionary and if so, replace the requested controller name with the custom controller name from the dictionary.
example;
My dictionary will contain data as follows Key: 'Home', Value: 'Home_IN' Key: 'Customer', Value: 'Customer_BE'
Now, the following request is made 'User/Edit/1'. Does the controller name exist in the dictionary? No, continue with original request.
Now, the following request is made 'Home/Details/2'. Does the controller name exist in the dictionary? Yes, replace the original controller name 'Home' withe custom controller name 'Home_IN' so changing the requested URL to be 'Home_IN/Details/2'.
Does this make sense?
My problem here is knowing exactly where in the request cycle I need to do this?
I am assuming I need to create my own custom controller factory?
I'm very new to MVC so this is a simple issue, just can't seem to find any information on why it's happening so turning to the forums. Edit works, delete sort of works (that's another issue in itself), and details works, but create causes an issue. I've debugged the form being passed in and it's always null with default values. It's almost identical code to my edit so I'm not sure why edit works and create won't. I'd show code for the view but since it's working for edit I'm currently ruling that out as the problem. "Colleges" in this populates a dropdown in the view. Here's the code:
but the problem is that when i click on the Perform Link an error will be raised indicating that it can not find the Calculate view.
so how i can enforce my application to call the Calculate controller method to perform the update and to keep the user in the current page .(the index page).
I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<% if (Model.HasRSVP(Context.User.Identity.Name)) { %> <p>
You are registered for this event!
<%: Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"}) %> </p> <% } else { %> <p>................
I have just started using MVC. I created the MVC application and was playing around with it.When you call the http://localhost/home/Index/ on the sample MVC application the Index method of the controller home gets invoked and the view Index.aspx is displayed and similarly when we call http://localhost/home/About/ then the About method of the Home controller is invoked and the About.aspx page is displayed
Imports System.Web.Mvc Public Class AssetController Inherits Controller Public Shared Function ScriptTag(ByVal src As String) As String Return String.Format( "<script type='text/javascript' src='/js.mvc?src={0}&{1}'></script>", System.Web.HttpContext.Current.Server.UrlEncode(src), New BuildVersion().ToString() ) End Function End Class
The project has a reference added to the 3.0.0.0 version of System.Web.Mvc assembly. When I try to view the page in a browser, I get a HTTP 500 with this message:
BC30007: Reference required to assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the base class 'System.Web.Mvc.Controller'. Add one to your project.
What gives? I don't understand why I can use this controller everywhere in our ASP.NET Forms/MVC hybrid application, but not in a view. EDIT: In fact, when I type <% System.Web. into the .aspx view, Mvc doesn't even appear in Intellisense!
I am using the Nhibernate with MVC. In the controller i am getting the model from the HttpSession. How can i set the model from controller Unit testing method.
Is it possible to retrieve the URL of a 3rd party webservice calling my controller method? Things like Request.Current.Url refer to my own URL (/someController/someAction/).
The 3rd party webservice is sending HTTP POST data to my /someController/someAction and I wish to send back a HTTP POST message to the caller of the method, the 3rd party webservice, without using
return Content["some response"] which will force me to exit the method. Since the answer is plain text I would like to send it using HTTP Post.
What I actually try to do is respond to the calling webservice without exiting my method (return Content() will exit) so I can call other methods to process the data send to me by the webservice. I want to first tell the webservice I received their stuff and than process, in this way when a processing error occurs the webservice at least will not resend old data. Is there another way to do this than building your own HTTP post?
I have a form with a drop down list. I want to pass the value of the selected item and a hidden field called stidentid to a controller action that would check my database to see if records for that id and semester exist and return the view with the appropriate values filled in. I'm not really familliar with Javascript or Jquery so I tried this:
[Code]....
}).change();
however nothing happens when I select anything from the semester list not even a crash. What am I doing wrong?
I am using an Zencoder API to transcode video files. Once the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.
So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?
excuse me for the underlines, i thought that would make my query stand out.
I have checkboxes that I have created using Literal now on postback I get the checkboxes which are checked in the Request.form.Allkeys. However I don't know how to read those values how can I use them? how can I count how many values are in there and how can I find some values in there example I want to find if the request.forum.allkey contain forumaName0 ..
Just wondering if anyone has any idea how you can determine how many bytes of a request have been read/received by the server... In other words how do I stream http request...
In that, users are uploading files and I want to report on a perotic basis how many bytes have been read/received so far.
