  • Using Session Vars in a MVC Domain Model library

    - by 104286623826380127552
    Hello to all. I have a IQueryable function. In that function, I need to store and retrieve data to Session; can you guys point me in the right direction. I've looked at the HttpSessionStatBase where the session is usually taken from HttpContext.Current but this doesnt seem possible to do in the library. Am I missing something? Thanks in advance.

  • Passing additional data value to strongly typed partial views in ASP.NET MVC

    - by fearofawhackplanet
    I have an OrderForm domain class, which has property subclasses, something like: interface IOrderForm { int OrderId { get; } ICustomerDetails CustomerDetails { get; set; } IDeliveryDetails DeliveryDetails{ get; set; } IPaymentsDetails PaymentsDetails { get; set; } IOrderDetails OrderDetails { get; set; } } My "Details" view is strongly typed inheriting from IOrderForm. I then have a strongly type partial for rendering each section: <div id="CustomerDetails"> <% Html.RenderPartial("CustomerDetails", Model.CustomerDetails); %> </div> <div id="DeliveryDetails"> <% Html.RenderPartial("DeliveryDetails", Model.DeliveryDetails); %> </div> ... etc This works ok up to this point, but I'm trying to add some nice ajax bits for updating some parts of the order form, and I've realised that each of my partial views also needs access to the IOrderForm.OrderId. Whats the easiest way to give my partials access to this value?

  • Widget_Controller for different types of data (MVC)

    - by steve-o
    Hello, I have a few widgets I need to show on a site - they are all relating to different types of data (e.g user, house). Each type of data and its relations is represented in specific models, but as far as a controller or helper is concerned, is it an ok plan to have a generic Widget controller/helper which generates the necessary widgets, even though each widget is dealing with distinct data? I don't really want to generate these widgets within the User and House controllers, as these controllers are dealing with different types of functionality. I'd imagine that the Widget_Controller could just contain static methods for generating these widgets, e.g: Widget_Controller::user_panel(); Does that make sense? Cheers!

  • Best Design Pattern to Implement while Mapping Actions in MVC

    - by FidEliO
    What could be the best practices of writing the following case: We have a controller which based on what paths users take, take different actions. For example: if user chooses the path /path1/hello it will say hello. If a user chooses /path1/bye?name="Philipp" it will invoke sayGoodBye() and etc. I have written a switch statement inside the controller which is simple, however IMO not efficient. What are the best way to implement this, considering that paths are generally String. private void takeAction() { switch (path[1]) { case "hello": //sayHello(); break; case "bye": //sayBye(); break; case "case3": //Blah(); break; ... } }

  • ASP.NET MVC Generic Partial

    - by gnome
    Is is possible to have a partial view inherit more than one model? I have three models (Contacts, Clients, Vendors) that all have address information (Address). In the interest of being DRY I pulled the address info into it's own model, Addresses. I created a partial create / update view of addresses and what to render this in other other three model's create / update views.

  • Hint to MVC view generator for primary key on POCOs

    - by myotherme
    When generating a strongly-typed Index view for my model I always get the following: <%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> I am using a POCO class for use with our ORM. As I understand it when using LINQ to SQL the view code will know which field is the primary key. Is there a way that I can an attribute to the property (or class) that will let the View Generator know that the ID property if the primary key?

Consider this code: [HttpPost()] public void Update(IAuctionItem item) { RedirectToAction("List"); } Whenever I call this I get an exception saying I can't create an instance of type which i totally correct. But is there a way of telling what the interface should map to without actually using the concrete type ?

  • Pass List of models to controller ASP.NET MVC 5

    - by user3697231
    I have a view where user can enter some data. But problem is this: Let's say you have 3 text box on view. Every time user can fill multiple times this 3 text boxes. To clarify, let's say user fills this 3 text boxes and press button which adds on form again these 3 text boxes. Now when user clicks submit this form is sent to controller, but how do I sent List of models as parameter. My architecture for this problem is something like this: MyModel public int ID { get;set; } public string Something { get; set; } /*This three textboxes can user set multiple times*/ /*Perhaps i Can create new model with these properties and then /*put List of that model as property here, but how to fill that list inside view ??*/ public string TextBoxOneValue { get; set; } public string TextBoxTwoValue { get; set; } public string TextBoxThreeValue { get; set; } Now, i was thinking that i Create PartialView with this 3 text boxes, and then when user clicks button on view another PartialView is loaded. And now, let's say I have Two partial views loaded, and user clicks submit, how that I pass list with values of these 3 text boxes to controller ??

  • ASP.NET MVC Access model data in masterpage

    - by Paul
    I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

  • Tracking user changes in ASP.NET MVC

    - by Ian Roke
    I have a requirement to track what authenticated users change with regards to the data when logged in. I don't need to track what pages they look at although that could be very useful in future. I have thought about saving the User Guid but that seems very clunky. Are there other methods/best practises?

  • C# and ASP.NET MVC: Using #if directive in a view

    - by Mega Matt
    Hi all, I've got a conditional compilation symbol I'm using called "RELEASE", that I indicated in my project's properties in Visual Studio. I want some particular CSS to be applied to elements when the RELEASE symbol is defined, and I was trying to do that from the view, but it doesn't seem to be working. My view code looks like this (shortened a bit for demo purposes): <% #if (RELEASE) %> <div class="releaseBanner">Banner text here</div> <% #else %> <div class="debugBanner">Banner text here</div> <% #endif %> With this code, and with the RELEASE symbol set, the 'else' code is running and I'm getting a div with the debugBanner class. So it doesn't seem to think that RELEASE is defined. It's worth noting that my actual C# code in .cs files is recognizing RELEASE and runs the correct code. It's only the view that is giving me the problem. Does anyone have any insight into this? Any help would be appreciated. Thanks.

  • ASP MVC Creating Form Rows Dynamically

    - by Jonathan Stowell
    Hi Guys, I haven't even attempted this yet and am creating this question for advice really. I have a strongly typed page which receives a form model composed of several components. It is to create a mitigating circumstance (MC) for a student at a university for my final year project. A MC can be composed of the initial problem, assessment extensions, and I use a multi select box to allow the user to select staff retrieved from the database which are able to view the MC once created. The thing is I feel that a student could be granted many assignment extensions for one problem. I am wander if it is possible to include a button/image on the form which when clicked will create a new assessment extension object, and duplicate the form components to set the values for the object? This would all need to occur without any page refreshes. Any advice, or links to good tutorials would be appreciated. I have so far been unable to find any suitable examples. Thanks, Jon

  • Question about architecting asp.net mvc application ?

    - by Misnomer
    I have read little bit about architecture and also patterns in order to follow the best practices. So this is the architecture we have and I wanted to know what you think of it and any proposed changes or improvements to it - Presentation Layer - Contains all the views,controllers and any helper classes that the view requires also it containes the reference to Model Layer and Business Layer. Business Project - Contains all the business logic and validation and security helper classes that are being used by it. It contains a reference to DataAccess Layer and Model Layer. Data Access Layer - Contains the actual queries being made on the entity classes(CRUD) operations on the entity classes. It contains reference to Model Layer. Model Layer - Contains the entity framework model,DTOs,Enums.Does not really have a reference to any of the above layers. What are your thoughts on the above architecture ? The problem is that I am getting confused by reading about like say the repository pattern, domain driven design and other design patterns. The architecture we have although not that strict still is relatively alright I think and does not really muddle things but I maybe wrong. I would appreciate any help or suggestions here. Thanks !

  • How to mimic an excel spreadsheet on a website in vb.net?

    - by user1439659
    I am building a website to capture data. I have many spreadsheets that are used for data entry or capture. Now I want to mimic these complex spreadsheets on the web forms but I am unsure of the correct control to use. Data entry must be allowed and live calculations also need to be made similar to formulas on normal excel spreadsheets. Later on the data must be captured into an SQL table. What would be the best control to use or method to mimic that functionality, albeit that the spreadsheet component is no longer available in visual studio 2010. Is it a data grid? Thanks
