MVC :: Display Foreign Key-bound Property From Model View
Apr 17, 2010but I am new with MVC and database-driven applications.
I hava a table with Cities (ID,Name) and one with Businesses(ID,CityID,Name). The later has a foreign key relationship with the first table.
I used a linq-to-SQL class to create my models.
My problem is that I need to access the City Name(not the ID) when displaying the Business Model View.
How can I do this? if from my controller I call the View passing the auto-generated Business Model, I only have access to the ID.

I wonder why the ACCVM.newMtn0130 become null after RedirectToAction? I already assign with "_ACCVM.newMtn0130 = newMtn0130".
ACCVM._Error didn't become null after RedirectToAction.
How To Return Errors To View From Controller Not Tied To A Specific Model Property
Aug 26, 2010Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)
I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)
Example - A user tries to log in, and their credentials do not match a known user.
Model View Control Versu Model View Presenter
Jun 2, 2010I have been reading about different model for development
model view control mvc
model view presenter MVP
Model view view model MVVM
i belive MVC has two big Advantage over webform 1) TDD 2) More control on HTML
MVP is bit variation in mvc model. rapid development as well as 1) TDD 2) More control on HTML (correct me if i m wrong) see the below link

C# - MVC View Model Text Data Lost After The Post - Display Them In The Case Of Failed Validation?
Nov 12, 2010I'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?
View 2 RepliesShould Data Annotations Be On The Model Or The View Model
Dec 15, 2010I'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.

MVC :: View Model To Convert To Domain Model?
May 4, 2010Say 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.

Dec 29, 2010've created a Search partial view and it works, except for my view model.

MVC2 View Model For Multiple View Forms And Data
Aug 26, 2010one 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.
View 2 RepliesMVC :: View And Partial View Sharing The Same ViewData.Model?
May 3, 2010making 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 :

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).

C# - How To Pass Model From A View To A Partial View
May 5, 2010I have a view that is not strongly typed. However I have in this view a partial view that is strongly typed.How do I do I pass the model to this strongly typed view?I tried something like
public ActionResult Test()
{
MyData = new Data();
MyData.One = 1;
return View("Test",MyData)
}
In my TestView
<% Html.RenderPartial("PartialView",Model); %>
This give me a stackoverflow exception. So I am not sure how to pass it on. Of course I don't want to make the test view strongly typed if possible as what happens if I had like 10 strongly typed partial views in that view I would need like some sort of wrapper.
MVC :: Getting The ID For A Model Property From HTML Helper
Jan 25, 2011Is there a way to retrieve the client side ID for a model property similar to how the helpers like LabelFor etc generate the ID? For example, I have a model with a DateOfBirth property. I want to hook up that field to a jQuery DatePicker. Normally, I would hook up the date picker like this:
[Code]....
This works fine but hard codes the DateOfBirth property name. Ideally, I would like to use this:
[Code]....
Is this already available out of the box somewhere? I just created an extension method on the HtmlHelper class that does exactly this, but I wondered if there was already something built-in so I don't have to reinvent and test the wheel.
MVC :: Bug - Get Value From Route Parameter Instead Of Property Of Model
May 18, 2010I found little bug feature in MVC 2.
So, if we have in route defined parameter with same name as property at model and then we call it from strongly typed HTML helper (for example Html.TexBoxFor(x => x.PropertyName)), we get value from route parameter instead of property of model.
For example.
We have defined follow route:
[Code]....
Very simple model:
[Code]....
Next action in controller:
[Code]....
And very simple view:
[Code]....
Result you can see at follow picture:
I think what this dirty example described the essence of the problem. Let me know if I'm wrong.
MVC :: UpdateModel Calls A Property Get On The Model?
May 4, 2010as the behaviour of the UpdateModel<T> changed in MVC 2 (RTM)? Since then I have the following problem when UpdateModel is called:UpdateModel<T1>(record, properties);record is typeof(Jumbo.Juist.Models.Bezorging) and properties is a string[] containing "Winkelnummer" and "OudRoutenummer".This now fails, because a get-property is being accessed: BerekendeAankomstTijd. In the past, it didn't fail. IMHO, this validation should be skipped, because it's only a getter (and thus/also not included in the string[] of properties to update)

C# - MVC - Using Model Property As Form - Post To Action?
Jan 12, 2011public class BandProfileModel
{
public BandModel Band { get; set; }
public IEnumerable<Relationship> Requests { get; set; }
}
and the following form:
<% using (Html.BeginForm()) { %>
<%: Html.EditorFor(m => m.Band) %>
<input type="submit" value="Save Band" />
<% } %>
which posts to the following action:
public ActionResult EditPost(BandProfileModel m, string band)
{
// stuff is done here, but m is null?
return View(m);
}
Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.
The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work. What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action?
