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:
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.
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 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 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 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 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?
My ascx is pretty big & I'd like to reuse it, changing controller/method in Html.ActionLink with another controller/method. Method of another controller has the same signature as PersonController.Publications. Whats best way how to make controller/method configurable for my layout.
I have a web app with a table of statistics on our salesmen's customers, and each row has a sparkline graph showing the general trend of the sales data for the last 12 months. Each page shows a particular salesman's customer list, and some of them can have an enormous number of customers = an enormous number of rows = an enormous number of sparklines (e.g. one in particular has 125 and takes 15 seconds to load).
For this reason, jQuery sparklines could not be used - they completely pinned the CPU of a user accessing a page with a lot of sparklines with IE.
So I moved on to using the Google Chart API, which worked much better, except for two issues: 1) it's on a secure site, and the Google Chart API URL is only served over HTTP (solved by using a small wrapper script to download the graph dynamically and re-serve it from our secure server); and 2) on a page with 125 sparklines, it was still very slow due to the number of requests (even when the 0-9 server prefixes are used to maximize the # of available connections).
So my next step beyond this was to try to make each of the "download/grab/re-serve image" method calls asynchronous - and it worked!
...but only on my dev box running in debug mode.
When I pushed it up to the live site, it was faster, but it left some of the images unloaded, which is of course unacceptable.
So here is what I was hoping some SO hotshot would know:
1) Why are my asynchronous method calls working while debugging, but not working on the live site?
2) Is there any easier way to get a large number of sparklines of some sort to load quickly on a secure server without making me want to tear my hair out?
2a.) Does anyone have any experience using the ASP.NET Chart Library? Is this something I should investigate?
2b.) A co-worker suggested I make my own sparkline routine using a 1x1 CSS background image and varying the height. The problems are a) it is completely un-extensible in case we want to make changes; b) it seems hacky as hell (leaves about a bajillion DIVs per sparkline in the markup); and c) I have no idea if it will be fast enough when there are 100-200 of them on one page - what are your thoughts on the feasibility of the 1x1 sprite approach?
