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 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

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 having a dropdown server control on view, when the user clicks the submit btn at that time the form gets posted. and a action method in view controller is called with verb=post.
But the problem is that how should i get reference to the dropdown server control in the action method of view controller?
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 have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
Can i create a partial view and a controller that will feed data to the view, and if i render that partial in a Master page, the Data will show on whatever URL i am?
Or is there another way of showing content from database on every page(view)?
I am creating an ASP.NET application that allows users to edit and insert data that is persisted in a SQL Server database.I would like to implement a controller class that handles queries for certain entities, caches results and triggers events when data is inserted or updated.I need one of these controller classes for each entity in my data model.What I'm unsure of is how to create a singleton class of this sort that different user sessions can access.
For example,I have a Employee entity in my data model.I would like to have an EmployeeController class that handles retrieving the employees from the database, sends inserts and updates to the database,keeps a cache of all employees and triggers events when an employee is inserted or updated.Objects in other user sessions could then listen and respond to these events.
Am I on the right track?Should I be using the ASP.NET MVC framework to accomplish this?How do I instantiate these controller classes when the first user needs them and have subsequent concurrent users access the same class?
EDIT:I've been researching the idea of a controller class as an anti-pattern since @TomTom's answer.I'm not convinced one way or the other.I still need an answer to question #3 above.Let's just drop the specific idea of a controller class for now. How do I create any class that is:accessible by multiple user sessions,allows only one instance,is deleted if there are no user sessions,and triggers events that other classes can listen to.
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:
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,
've created a Search partial view and it works, except for my view model. What i mean is, the partial view sends a string to my ActionResult Method, but only a string, that is not related to the view model that the partial view is built in. If i tell my ActionResult method to receive the view model in which the partial view is built in, it always tells me that i have null values. Here's my code This is my partial view:
[Code]....
Now here is my Model in my MoviesSearch view model:
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 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.
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?
