  - by Felipe

  Hi everybody I'm begginer in asp.net mvc and i have some doubts.

• What is the benefit to wrapping every sql/stored proc invocation in a transaction?

  - by MatthewMartin

  The following code executes one stored procedure. The stored procedure has only one command in it. Is there any benefit to wrapping everything in a transaction, even it only has one SQL statement in it (or one stored proc that has only one sql statement)? In the sample code below, if the delete fails, it fails. There is nothing else to be rolled back (it seems). So why is everything wrapped in a transaction anyhow? using (ITransactionManager transMan = repository.TransactionManager()) using (IController controller = repository.Controller()) { transMan.BeginTransaction(); try { //DELETE FROM myTable where Id=@id controller.Delete(id); transMan.CommitTransaction(); } catch { transMan.RollbackTransaction(); throw; } }

• ASP.net MVC support for URL's with hyphens

  - by John

  Is there an easy way to get the MvcRouteHandler to convert all hyphens in the action and controller sections of an incoming URL to underscores as hyphens are not supported in method or class names. This would be so that I could support such structures as sample.com/test-page/edit-details mapping to Action edit_details and Controller test_pagecontroller while continuing to use MapRoute method. I understand I can specify an action name attribute and support hyphens in controller names which out manually adding routes to achieve this however I am looking for an automated way so save errors when adding new controllers and actions.

• JSF Rendering Issue (Page getting cached)

  - by Shamik

  I am facing a strange issue with JSF. I have developed one controller and bind it to request scope. I need to access one jsf page like http://localhost:8080/selectRule.jsf?type=A and on the same IE session I want to issue another request like http://localhost:8080/selectRule.jsf?type=B as we can see, only the type is changing here. This is why I have a ruleController bound to request scope, so that every request, creates the controller and pulls out the data depending upon type. I have a private HtmlSelectOneMenu choices item in the page. What I see is, somehow only once in the session the getChoices() is getting called. This is what I see For each url, one new ruleController object is getting created. Only first time getChoices() are called. In the subsequent time, if I change the URL in the web browser, the getChoices() method are not getting called though a new controller is getting created. Note: I am using JSF 1.1

• in jqgrid, how can i have the editform disappear after submit

  - by leora

  right now, when i click submit it sends a message to the server and updates the databased and refreshes the screen but it keeps the edit form popup on the screen. Is there anyway to have it disappear once the submit is complete. its kind of annoying because its a little unclear that you are done because the form just sits there (even through the grid has refreshed) i have closeAfterEdit and closeAfterAdd set to true but it doesn't seem to do anything. jQuery("#grid").navGrid("#pager", { }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterEdit: true, url: siteRoot + controller + "/Update" }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterAdd: true, url: siteRoot + controller + "/Add" }, { reloadAfterSubmit: true, url: siteRoot + controller + "/Delete" }, { multipleSearch: true }

• Two parameters in asp.net mvc route

  - by olst

  Hi. This is a modification to a question I've asked before on this forum. My controller action: public ActionResult SearchResults(string searchTerm, int page)... My view: <%= Html.PageLinks((int)ViewData["CurrentPage"], (int)ViewData["TotalPages"], i => Url.Action("SearchResults", new { page = i }))%>... The route entries: routes.MapRoute( null, "SearchResults", new { controller = "Search", action = "SearchResults", page = 1 } // Defaults ); routes.MapRoute( "Search", "SearchResults/Page{page}", new { controller = "Search", action = "SearchResults" }, new { page = @"\d+" } ); My goal is to have paging links for the search results. The problem is that when I click any page in the paging links, it gives me the search results of an empty serach term. How can I pass the search term parameter which is a string in addition to the page number parameter ? What should I put in the routing ?

• What object called a method in Obj-C

  - by Loz

  Hi, I am looking to write a plugin controller in Cocoa that loads bundles, and exposes a specific set of methods for the plugins to call. My question is this: is it possible to know (any) info about the object that called a method in the controller. When an instantiated plugin calls a method in my plugin controller, I would like to know which of the plugin instances called the method, without having to rely on the plugin sending a pointer to itself as a parameter (I could always validate the pointer they send, but I want to keep the API methods as simple as possible). There may be no perfect solution (and there are simple workarounds), but it's always good to learn some new tricks if possible (or the reasons why it's impossible). Thanks in advance.

• In ASP.NET MVC, how does response.redirect work?

  - by Swoop

  I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

• MVC4 not binding a list of basic types

  - by admanb

  I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

• jQuery hover() event on div element within a button element

  - by jakeisonline

  I can't seem to get jQuery to notice the div within the following markup <button class="button submit positive right" id="omnisubmit" type="submit"> <div class="label">Submit</div> <div class="controller">&nbsp;</div> </button> And here is the jQuery I'm currently using: $("button#omnisubmit div.controller").hover(function () { console.log("Hover..."); }); However, jQuery doesn't seem to pick up when the mouse is hovering over that div, $("button#omnisubmit div.controller").hover( works correctly, of course. I have a feeling it's because putting divs inside buttons may not be standard HTML?

• TabBars and iOS 7

  - by MichaelScaria

  I have a UITabbarController that I'm pushing another controller on top of using a UINavigationController. On iOS 6 and below, the tabBar of the parent controller slides away and the toolbar of the new view controller is presented. But on iOS 7 the tabBar doesn't animate away even if I run the code [self.navigationController setToolbarHidden:YES animated:NO]; EDIT - Okay I narrowed my problem to iOS 7 not respecting the hidesBottomBarWhenPushed property, I followed the answers in hidesBottomBarWhenPushed ignored in iOS 7 but it didn't work. The view that is pushed has a toolbar with buttons and the buttons are responding to touches, it's just that the tabBar is on top of the toolbar.

• How do I keep subdomain.domain.com links from mapping to subdomain.domain.com/subdomain?

  - by Alan Jackson

  I have a virtual directory created and a sub domain that points to that virtual directory. My links always route to subdomain.domain.com/subdomain/controller/action when they can leave off the subdomain link. Is there an easy way to stop that? Also, it's the same problem when I mapped anotherdomain.com to my virtual directory. It ends up linking to anotherdomain.com/virtualdir/controller/action. It just looks unprofessional to me to have all my links be myapp.com/myapp/action/controller.

• How to stub Restul-authentication's current_user method?

  - by Thiago

  Hi there, I'm trying to run the following spec: describe UsersController, "GET friends" do it "should call current_user.friends" do user = mock_model(User) user.should_receive(:friends) UsersController.stub!(:current_user).and_return(user) get :friends end end My controller looks like this def friends @friends = current_user.friends respond_to do |format| format.html end end The problem is that I cannot stub the current_user method, as when I run the test, I get: Spec::Mocks::MockExpectationError in 'UsersController GET friends should call current _user.friends' Mock "User_1001" expected :friends with (any args) once, but received it 0 times[0m ./spec/controllers/users_controller_spec.rb:44: current_user is a method from Restful-authentication, which is included in this controller. How am I supposed to test this controller? Thanks in advance

• What causes a UIViewController to become active?

  - by Rob Bonner

  I am sure this is an easy question, but one that has escaped me for some time now. Say I have a UIViewController, either defined as a root in an XIB or on a stack. At some point in my code I want to replace it with another view controller. Just flat out replace it. How would I do that? I have tried defining the controller and assigning, but not sure what actually makes it push on the screen with the absence of a navigation controller.

• @ExceptionHandler doesn't handle the thrown exceptions

  - by Javi

  Hello, I have a method in my controller which will handle the exceptions thrown by the application. So I have a method like this one. @Controller public class ExceptionController { @RequestMapping(value="/error") @ExceptionHandler(value={Exception.class, NullPointerException.class}) public String showError(Exception e, Model model){ return "tiles:error"; } } And to try I if it works I throw a NullPointerException in another method in other method controller: boolean a = true; if(a){ throw new NullPointerException(); } After the exception is thrown it is printed in the JSP, but it doesn't go throw my showError() method (I've set a breakpoint there and it never enters). showError() method will catch the exception and will show different error pages depending on the exception type (though now it always shows the same error page). If I go to the url /error it shows the error page so the showError() method is OK. I'm using Spring 3. What can be the problem? Thanks.

• How to test that action uses argument?

  - by Caster Troy

  I am supposed to be using test-driven development but in this particular case, as I am having trouble, I implemented the action method first. It looks like this: public ViewResult Index(int pageNumber = 1) { var posts = repository.All(); var model = new PagedList<Post>(posts, pageNumber, PageSize); return View(model); } Both the repository and the PagedList<> have been tested already. Now I want to verify that when the action is given a page number that the page number is actually considered. private Mock<IPostsRepository> repository; private HomeController controller; [Test] public void Index_Doohickey() { var actual = controller.Index(2); // .. How do I test that the controller actually uses the page number here? }

• Why do we need Web-Api? [closed]

  - by user437973

  I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.

• Windows Form Components Access

  - by rxm0203

  What is the best way to access components (e.g. imagelist, timer) from a form instance? I am working on multi form windows forms application on .NET Compact Framework version 3.5 SP1 with C#. I have a Controller class associated with each form for MVC implementation. Here is my sample Controller class. public class Controller { public void Init(Form f) { //f.Controls will allow access to all controls //How shall I access imagelist, timer on form f. } } My question is how can I access non visual components without taking a performance hit of reflection? Any code snippets are welcome. If reflection is only way, then can you provide me optimal way for components access please? Thanks,

• Creating non-framework calsses in CakePHP

  - by Affian

  I'm making a tournament manager in CakePHP 1.3 and I have a tournament controller which is fine but I want to implement a interface that can be used to define how a tournament runs. the controller needs to load a concrete class that implements the TournamentStyle interface that defines how the tournament works. At the end of a round the TournamentStyle is used to calculate the scores and winners and generate the next round of matches. That gives me a .php file for the interface and other files for the various styles. My question is: where would I put these files and how would I load them into my tournament controller?

• Passing a variable that can be updated

  - by Rob Bonner

  This seems like a simple thing, but can't get it to work. I pass a variable into a UIViewController thourgh a standard property: [aViewController setProposedDate:proposedWorkLog.entryDate]; which is retained by the controller, and possible changed. I have verified that in the controller, the data is modified. But, after it is popped off the stack and I look in the calling view, the data has not been updated. Is there a way to pass this variable and have it retain the new value, or a way to pass back a response from a closing view controller? Thanks!
