I have an user view model that has the following properties:
public User user;
public List<Language> Languages;
I send the above model to the view and use html helpers to build the form, so I end up with something like:
<form action="/Users/Edit/5" method="post"><input id="user_UserId" name="user.UserId" type="hidden" value="5" />
First Name
Last Name
Email
Language
Now, I try to read the POST in something that initially was something like :
[AcceptVerbs( HttpVerbs.Post )]
public ActionResult Edit( int UserId, FormCollection form ) {
and cannot get the user.UserId variable, user.FirstName variable etc.
what needs to be done to be able to read this kind of POST request. I'm kind of reluctant to modifying my ViewModel as it is very simple and easy to maintain as it is.
What I want to achieve is the ID of the property: item.Item.ID to be bound to the ID from the (route)URL. However I can't get it to work. I tried using [Bind()] attribute.
I fixed it now using a hidden field in the form like so:
<%= Html.HiddenFor(model => model.Item.ID)%>
However this feels a bit icky. I'd like to know if there is a better cleaner way of doing this?
I am using ASP.Net MVC2 and LINQ to SQL. I am using DataAnnotations and model binding in conjunction with a Form/View and its working beautifully well. Loving that.. My view is an "Add new Employee" form that's adding a new "Employee" complex object. Every Employee also has a child complex object called an "Address". I am using the bound Html helpers in the view, such as Html.TextBoxFor(model => model.NewEmployee.FirstName) for example. Working beautifully well, validating beautifully well both client and server and coming into the controller fully populated and ready to be saved! Exciting.. ModelState.IsValid returns true and I go to save the new Employee.
The Employee is created fine but the system also creates a blank/new Address record in my Addresses table even when the Address fields are blank! How can I prevent any Address from being created, in situations where I ONLY want to create a new Employee with no Address. An example is when the user supplies an existing Address, then I wish to simply set the new Employee's AddressID to that of an existing physical address (I hope that makes sense). But it could apply to any situation where you need to create a new complex object, but you don't wish for LINQ to create any of its child complex objects. I have tried setting NewEmployee.Address = null after it is received in the controller, but even after that, a blank/new Address is still created. Even if I try NewEmployee.Address = SomeExistingAddress, it does correctly link the Employee to the existing Address, but it STILL goes off and creates another redundant new/blank address record! Which is really weird..
I have a "Create New Employee" ASP.Net MVC form. My complex object is an Employee and an Employee has an Address, which is another Complex object. On my View/Form I collect all required values for both the Employee and the Address. I'm using the bound HTML helpers such as: Html.TextBoxFor(model => model.EmployeeAddress.StreetName)
This is all working beautifully well. Model binding is working like a dream, both server side and client side validation using DataAnnotations is working beautifully well and I am nicely receiving my populated complex objects as expected in the Controller.. Now I'm trying to save.. The Employee should always be newly created, because its an "Add New Employee" form. But sometimes the Address is an existing Address and I don't want to insert another one. Rather, I just want to link the Employee to the existing AddressID of the one that already exists in the database.
So I wrote a nifty GetExistingOrCreateNewAddress(Address PostedAddress) method which works great so I end up with the correct Address to use and link to the about to be saved Employee object. This is all happening in the same DataContext, so no problems there..
BUT even when I link the about to be saved Employee object to an existing Address, on save a new/empty Address row is created in my Addresses table. Even though the newly created Employee does link correctly to the existing Address I told it to! Why is it so??? And how can I save the new Employee without LINQ automatically creating a blank Address for me. Because I'm explicitly specifying an existing Address it should be linked to instead!
[HttpPost] public ActionResult CreateEmployee(EmployeeDetailsViewModel NewEmployeeDetails) { if (ModelState.IsValid) { EmployeeRepository ER = new EmployeeeRepository(); // Fetch or Create the appropriate Address object for what has been entered Address ActualAddress = ER.GetExistingOrCreateNewAddress(NewEmployeeDetails.EnteredAddress); // Link this Address to the "about to be saved" Employee NewEmployeeDetails.Employee.Address = ActualAddress; // Lock it in.. ER.SaveNewEmployee(NewEmployeeDetails.Employee);
I have a question regarding validation of drop-down list values. I have a view that is bound to a view model type called ReservationData.
This object contains a property CustomerVehicles of type List<VehicleData>. VehicleDatahas two int properties VehicleMakeId and VehicleModelId.
On my view I am trying to loop over the number of items in the CustomerVehicles collection and displaying two dropdowns for each, a vehicle make dropdown and a vehicle model dropdown usingDropDownListFor.
When I try to submit and validate I do not see any validation errors displayed on the screen.
Just in case you are wondering I have added a ValidationMessageFor for each dropdown as well. I am not sure if this is an issue with the structure of my view model and its complexity and how the controls need to be named or how the ids need to be set.
Here is the code for the looping over the collection:
I have a somewhat complex model that I need to pass to a MVC 2 Create view so its properties can be filled out. I'm not sure how to actually create this model as it has some relationship data that must also be filled out during the creation process.My main model is a Game. Most of its properties are scalar. It contains a foreign key to Content, for the game reviews, and there's a many-to-many relationship between Games and Platforms - games can be on a variety of platforms (PS3, XBox 360, etc.), and each platform has a library of games.When I pass data to my Edit view, it's as simple as:
[Code]....
I'm unsure what to do in the case of Create as I'm not sure how to link the associated parts - Content and Platforms - to a Game object.
I've got a view model that has some text properties. And I use Html.DisplayFor to display them on the screen. But those text data won't be post back, so in the case of failed validation, the returned view won't have those data. How do I handle this kind of situation?
I'm displaying the values in ViewData.Model in a View (.aspx) -- After the user looks them over, when the user clicks the "Submit" button that I have in this view, I want the ViewData.Model passed to another controller, but I'm not sure how to do this.
Currently, my target controller/action looks like this:
[Code]....
The "ViewData.Model" variable in this View is of type: List<Sample>
How do I pass the ViewData.Model to the RegisterController / Samples (action) ?
Basically I have a page where a user can select up to 3 vehicles by make and model. I have 3 divs on the page that is generated with a basic foreach loop. When the user selects a make and model from respective dropdown lists I am firing a javascript function that returns a JSonResult that loads a dynamic partial view into a seperate div. This partial view displays a div with a grid whereby the user can select one of n-number of services using a checkbox.Next what I would like to do is if the user selects a servce for the one of the vehicle selections, I would like to add this selection to a list of "ServiceSelection" that is part of my viewmodel. Ultimately the user would click a button that would redirect to the next step in the process and pass the entire updated viewmodel to this new page.
In my past I had created the following web page in web forms and I'm learning asp.net mvc right now , I had given it a tought and I run into conclusion I really wont know how to do the same page with asp.net mvc
before explaining you the actuall problem I would explain you the Model The model is a pretty simple , it for few columns which are bool , and a lot of them which are varchar(MAX) The View is built the following way
the bool parts of curse got a check box but the varchar parts are the complicated ones In my web form page i got the following code for each varchar property in my database
[Code]....
my server script gets the following page apon submit and checks if radio button 1 or 2 is selected if 1. it inserts the link as it is into colmn property while if it is 2. it saves the file on the server and saves the file location into the colmn property.
I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.
my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.
Say I got a domain model as follows: (and my repository expect an instance of this object)
[Code]....
And a view model (which my views are based on)
[Code]....
At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.
So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.
What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.
I have an entity object as model input in my view. Not sure if it's the best approach, but I use the object references to get values from a related object.Let's say I've got a car entity and a manufacturer entity.Here's how it would look in my view
[Code]....
I've get a nullreferenceexception where the car entitity does not have a reference towards manufacturer. I'd like to output a " " if no manufacturer exists.
'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:
one thing that has been puzzling me since learning MVC2 is the following case scenario: I have a view which contains two latest news lists, a login form and a signup form. Every example I found on Views and View Models so far has a one-to-one example such as a simple login form etc. But how do I create a model that provides the properties and validation for a login and signup form and manages the data for the news lists. can I pass multiple models in the strongly typed view? When I created one model the form validation would fail as it expects all fields - login and signup to be filled. I am missing some advanced examples or information.
Customer Name : <Textbox> Phone : <TextBox> <button> : button to Add More <Textbox> Phone to add multiple Phone Contact Name : <TextBox> Address : <TextBox> <button> : button to Add More Form Contact add multiple Contact
making my first steps with asp.net mvc and I actually create a (very) small website.I have 1 controller : TasksController1 view : Tasks/Index.aspx1 Partial View : Tasks/AvailableSorting.ascx In my controller I have 2 methods :
[Code]....
In my Tasks/Index.aspx, I add my partial view (<% Html.RenderPartial("AvaliableSorting"); %>)
That sounds simple. But, It just doesn't work : the Index return a list of Task and the parial view (should) return a list of string.The index.aspx works perfectly, but the partial view doesn't get the right model ! he gets the model of the Index page (list of Task).
I would like to add a partial view to my view page
The view page contain a mode name "<IEnumerable<JvTake1.Models.VortN>>
And the partial view contain a model name "<IEnumerable<JvTake1.Models.VideoL>>" So, theoretically I think they were suppose to work together but no Can any one guide me how to make it happen?
I am totally a new bee in asp.net mvc. Let me now explain my issue. I have a strongly typed view which inherits from a view model Document. I want to have a partial view in that view itself. My code for this purpose is :
i wonder something about mvc post method. for example I created a view "strongly typed" from a model (MyModel).
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Demo1.Models.MyModel>" %> for Create actionsthere is two way. first one takes MyModel as parameter [HttpPost] public ActionResult cart(MyModel md, int someID) { //some code //..... return View(MyModel); } second one does not take parameter as model. [HttpPost] public ActionResult cart(int someID) { //some code //..... return View(Mymodel); }
for first one way, after form post the form values does not delete, I mean form does not cleared,after second one form is be cleared. why this diffirence?
I have a single model type to wrap up various models I want to use in my view:
public class QuestionViewData { public Question Question { get; set; } public IList<Answer> Answers { get; set; } }
Now, in my question view I pull the data from the Question object - that's fine. Secondly I iterate through all Answer objects and pass them to a partial view:
For each answer (in the partial view) I have some action buttons (like ratings). I'm using separate form POST's with hidden fields for every button. The problem is that I can't post the whole QuestionViewData model to my action method cause I only have the Answer object as model in the partial view. However, I need to return the complete question view from that action that takes QuestionViewData as model.
