MVC :: Master-Detail-UserLink: Strongly Typed View And Custom Nested ViewModel?
Jun 13, 2010
When I send a strongly typed ViewModel containing other ViewModels nested inside (basically spanning 3 tables into one object) all the data is correctly presented when debugging. However it complains at rendering time with an exception "Compiler Error Message: CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)"
and the error is thrown from mvc2-rtm-sourcessrcSystemWebMvcMvcViewPageControlBuilder.cs method:
ProcessGeneratedCode line 19
PageBaseType is null all the time

I have a view model as such:
public class MyViewModel
{
public MyObject myObject{ get; set; }
public List<MyList> myList{ get; set; }
}
I have a view with a form strongly typed to MyViewModel This view allows you to enter values for the properties of MyObject, as well as create a list of MyList objects. The List part works fine although I thought that would be the more difficult of the two. Assuming MyObject has a property Description I create a textbox to enter the value as such:
@Html.EditorFor(x => x.myObject.Description);
The text box renders with an id of MyObject_Description...The problem is when I post this to my controller action, MyObject does not get bound at all(althought the list items do as they recieve the appropriate IDs of "MyViewModel_MyList[guid].myListValue")
What am I doing wrong here??
EDIT: more info
The first line of the view is:
@model MyApp.ViewModels.MyViewModel
And the Action method:
[HttpPost]
public ActionResult Create(MyViewModel myViewModel)
{
}
I am passing a new MyViewModel into the partial view to begin...
public ActionResult Create()
{
MyViewModel model = new MyViewModel();
return PartialView(model);
}
EDIT 2
Ok When I render my partial view that contains the forms I call :
@{Html.RenderAction("Create", "MyController");}
this is called from within a View of type @model IEnumerable<MyApp.Models.MyObject>
(this view displays a list of currently existing MyOjects, and at the bottom the partial is rendered to allow the user to add another MyObject to the DB)

I would like to know how i can bind my form values to my strongly typed view from a MultiSelect box. Obviously when the form submits the multi-select box will submit a delittemered string of my values selected...what is the best way to convert this string of values back into a list of objects to attach to my model to be updated?
public class MyViewModel {
public List<Genre> GenreList {get; set;}
public List<string> Genres { get; set; }
}
When updating my model inside the controller i am using UpdateModel like below:
Account accountToUpdate = userSession.GetCurrentUser();
UpdateModel(accountToUpdate);
However i need to somehow get the values from the string back into objects. I beleive it may have something to do with model-binders but i can't find any good clear examples of how to do this.

Note: I will use the term "ViewModel" for both the ViewModel in WPF/Silverlight and the strongly-typed ViewData in ASP.Net MVC in the following text.
I would like to create both ASP.Net MVC and WPF/Silverlight clients for the same project (in other words, against the same DataModel), should I create a common ViewModel project or a separate ViewModel for each client technology?
I would like to believe a common ViewModel is the right thing to do, but the need to create Dependent Properties or JSON strings make it seem to be incompatible.
Maybe another solution is to put the common part of the ViewModel into the DataModel layer?

I have an application that is going to allow a user to create records of type Customer and Seller that have one section in common, but other fields that are unique to their types.
Both of these types will have an address block for their create view.
If I have a strongly typed Customer or Seller view, how can I use the view partial (containing the address block) that I've created? I've tried creating a view model, but I don't know how to have the create page inherit the Customer model and the addressBlock partial inherit the addressBlockForm partial model...

Long story short, I'm trying to add a few extra items to ViewData to make my life easier, and its an edge case that doesn't really justify its own model just for this one case. Keep reading for more specific details.
So I have a strongly typed edit view for one of my objects, everything works great until I try to put a dropdownlist on the view with an ID that does not match a property of my class.
I have this
[code]....
My expectation is that in the controller action that accepts the POST, I will manually use the FormCollection[] to read out that ID and populate MyOtherModel with the correct ID.

article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
[Code]....
The form collection comes back with the expected prefixes:
[Code]....
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
[Code]....
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
[Code]....
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!

How much time is spent compiling a view in ASP.NET?Of course I don't expect anyone to give me a number, but I think it's interesting to have an idea of how much time this takes because it could influence the way we implement things.For example, if the time is significant , then I might try to put every result that I need to display in the view in a model class instance (created just to hold the values in such a way that I don't even have to test for objects with null value) and then minimize to the maximum (uh?) the amount of C# code in the view thus decreasing the amount of time necessary to compile the view.Question Does this make sense? Give some thoughts on this one.

Can my strongly typed view use a generic with a constraint? The type I want to pass to the view is
RoleGrantedToPerson<T> where T: Aggregate I don't know what T is at design time, only that it is a child of the base class 'Aggregate' I have tried using
System.Web.Mvc.ViewUserControl<RoleGrantedToPerson<Aggregate>>
but at runtime I get an error that the type of the view model supplied does not match the type required.
Is there some syntax/method to accomplish this?

I am not sure why this happens, but when I have an Html.TextBoxFor(model => model.SomeObject.SomeProperty), when I post, the property of that object is always null.
When I look at the markup generated, I see <input type="text" name="SomeObject_SomeProperty" id="SomeObject.SomeProperty" value = "" />
If I change the helper to Html.TextBoxFor(model => model.SomeObject.SomeProperty, new {id = "SomeProperty"}) the controller is then able to pick the value up. Why is this happening? I feel as though I shouldn't have to be specifiying the id for the textbox as it works when fine when not using child objects on a view model, IE <%: HtmlTextBoxFor(model => model.SomeProperty) %>.

I have controller method that looks something like this:
[Code]....
notice the commented out line. This method used to return an IEnumerable<Sport> but now that I have used a LINQ query it is returning an IEnumerable of an anonymous type (I think that's the correct terminology - please correct me if I'm wrong).
Question I have is...can I add a strongly-typed view based on this anonymous type and if not, how do I write a view that can access this collection?

This way on my view I can have a list of ForumPost(s) and a form that would edit the post.This is what i see in the debug mode right before the save call:The problem is that when I try to Save/Update I get the following error:I already tried doing this:

with no luck. for some reason downcasting doesn't work and the model or row are still of type CommentsViewModel instead of ForumPost

Now I found out how to create custom html helpers
using System;
namespace MvcApplication.Helpers {
public class InputlHelper {
public static string Input(this HtmlHelper helper, string name, string text) {
return String.Format("<input name='{0}'>{1}</input>", name, text);
}
}
}
Now how to turn it into a strongly typed helper method InputFor Like it is in the framework?I don't need the Html.TextBoxFor method, I know it exists. I am just curious in how to implement this behavior myself and used this as a simple example.PS. I was looking in the mvc source code but couldn't find a trace of this mysterious TextBoxFor. I only found TextBox. Am I looking at the wrong code?

I try to use HtmlHelper.TextBoxFor with spark view engine but view crashed with exception "Dynamic view compilation failed. 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'TextBoxFor' and no extension method 'TextBoxFor' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found(are you missing a using directive or an assembly reference?)".
It is my _global.spark:

Note: I'm working with MVC3 RC and Razor views.I've got this model:
[Code]....
I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:
[Code]....
What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.

I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:
[Required(ErrorMessage = "Please enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Password", Description = "Your secreet password")]
public string Password { get; set; }
All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:
<%: Html.DescriptionFor(m => m.Password) %>
should produce following html: <span>Your secreet password</span>

My question is: How can I get posted data (strongly typed) from each partial view separately? Something like this:
[HttpPost]
public ActionResult Home(Model1 model1, Model2 model2, ...)
{
return View();
