Multiple Models Sent To A Single View Instance
Jan 5, 2010I'm trying to learn the ropes of ASP.NET MVC and so far so good. One thing which I haven't seen addressed yet is the 'right' or most elegant way to pass multiple data models to a view. To help put the question in context, take this example: Say I was making a blog. When I log in I want the home screen to display a list of all new unapproved comments, as well as a list of recently registered users, and a list of the most recently submitted blog posts.
Most discussions I've seen suggest strongly-typing the view page so it can be called with something like "return View(RecentComments)" and iterate through the comments in the view, or to cast the data model like "var NewUsers = (MembershipUserCollection) ViewData.Model". What I'm ideally after is the 'right', or at least a 'right-enough', way of passing multiple models while still maintaining appropriate logic separation.
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 :: Data Annotations, View Models & Multiple Controller Actions?
Feb 17, 2010quick question: I have a view on my HomeController which is used to create a new 'model'. This view posts to a different controller to keep things tidy. The problem I am having is when I enter invalid details into the form, the rules I specified never seem to make it back to the original view and thus my validation messages or summary never get populated. Is there a way around this because I am using a view model with two IEnumerable lists in it.
View 5 RepliesMVC :: Best Practice To Have Multiple Strongly Type Models Inside A Single View?
Oct 26, 2010So far I've seen demos of MVC that have simple pages, one for login, one for register, one for listing a table. In order to understand better the transition for WebForms developers into MVC patterns, I would like to understand how can I put together multiple CONTROLS (like the one provided by the default MVC project that VS2010 creates for us ...and make it work. OK so as an example, imagine we want to change the LogonUserControl.ascx to allow us to login (so to show UserName and Password textboxes and Logon button) from the Home Page.
1) We update the Control as follow:
2) We update the HomeController.cs file to handle the Logon Button Post event as follow:
We needed to move some code from AccountController to HomeController in order to get the control to work under the Index view. So ...with little luck it seems to work! Now the problem happens when you navigate to the Register view, considering that now we are not any longer on the HomeController "domain" but we are under AccountController. Register page shows perfectly and since the LogOnUserControl.ascx belongs to the MasterPage, it shows too. Since we are not logged yet, it will be displaying the UserName and Password textboxes. But we don't really care about that, because we are on the Register view and after populating the Register values, we click on the Register button. This is the error I get:
>>> To me that I come from the WebForms world, it seems like even if the event fired was the Register button (therefore under the AccountController domain), there is a kind of hidden OnInit event fired for any control on that view, in this case the Logon event. I'm sure this is NOT the case but the real question is... if we are allowed to have only one Controller x view, how can we put together controls that come from different "controller domains" and display them inside a single view?
Could I develop an eCommerce site using MVC that has the home page displaying different controls like [Most Purchased Product, Product of the Month, Special Promotions, Messages Inbox, Company Events ... and each control has it's own button to click and do something (so a proper POST request)] on the home page, unless I only have ONE single Controller which i'm not even sure if it will work or if it would make sense ....since MVC is all about separation of responsibilities.
MVC :: 2 - Dynamic View Content - Render A Page That Will Have Multiple Radio Button Groups As Well As Multiple CheckBoxes
Aug 4, 2010I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
table structure:
PackageID uniqueidentifier
PackageName string
ItemName string
RadioGroupName string
ViewControlName string
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
1 / "First Package" / "Item1" / "First Group" / "RadioButton"
2 / "First Package" / "Item2" / "First Group" / "RadioButton"
3 / "First Package" / "Item3" / "First Group" / "RadioButton"
4 / "First Package" / "Item4" / null / "CheckBox"
5 / "First Package" / "Item5" / null / "CheckBox"
6 / "First Package" / "Item6" / "Second Group" / "RadioButton"
7 / "First Package" / "Item7" / "Second Group" / "RadioButton"
8 / "First Package" / "Item8" / "Second Group" / "RadioButton"
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3)
A CheckBox (Item4)
A CheckBox (Item5)
A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:

C# - Can Send Different View Models To A View?
Feb 4, 2011I am implementing a view for Food. (ASP.NET MVC2) Then depending on the type (say fruit or vegetable for example) I will change the view.
Can I do this without creating a seperate view for fruit and vegetable?
I.e. Say we have url structure like [URL] and don't want [URL] [URL]
So I want to be able to change the view depending on the type. I'm using a tabstrip control from telerik, to give you an of the difference in the views - it'd just be say - not displaying one particular tab for Veg, and displaying it if fruit, for example.
Can a view accept two different view models ? so when we hit [URL] the code determines what type the object is (Fruit or Vegetable) then sends either FruitViewModel or VegetableViewModel ? If I just send one viewmodel how can I control the logic to display or not display certain things in the view?

MVC :: ViewMaster And View Contains Two Efferent Models?

MVC :: Strongly Typed HtmlHelpers And View Models?
Oct 26, 2010I 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) %>.
MVC :: Use Mutliple Models For One View Or Partial Views?
May 8, 2010I've recently began learning ASP.NET MVC.I created my first project, and added a model via Linq TO SQL. The first model handled a database table that held a list of menu items.I then created a view and the view would loop through all of the menu items returned by the controller and build a custom menu for me.
I then created a Model via Linq TO SQL to point to a table that hold's my site articles.I created a view that would itereate through all of the site articles returned by the controller and list them in the view.
Now I've taken the logic from the menu view and created a partial usercontrol view to build my menu. I've done the same thing with the SiteArticles.
How do I make the data from both of these modles availble in one view?I basically want to HTML.RenderPartial("MenuControl") in my master page and RenderPartial("ArticleControl") in the conent of the view.
I'm using the original view that i created to show articles..
So If i remove the rendering of the menucontrol user control from the master page and i call the view to show the articles, the articles will render because the controller knows to load the articles and return them to the view..
If i add the menu user control to the masterpage, I get an error because the view recieves data from the site article model/controller but not from the menu model/controller.

MVC :: How To Reuse Model Metadata For Custom View Models
Oct 19, 2010I'm working on an ASP.NET MVC 2 project with some business entities that have metadata dataannotations attributes applied to them (Validation attributes, Display attributes, etc.).
Something like:
[Code]....
Using the metadata from different views is no problem, as long as I am using my business entities as viewmodels or as part of a viewmodel like this:
[Code]....
However, sometimes I need to code a view for editing some, but not all fields of an entity. For those fields I want to reuse the metadata already specified in my user entity. The other fields should be ignored. I'm talking about custom view models like this:
[Code]....
That's where I am running into problems. The custom view model above leads to an exception when the view is generated, because it has no password property.
The associated metadata type for type 'Zeiterfassung.Models.ViewModels.Users.UserNameViewModel+UserModel' contains the following unknown properties or fields: Password. make sure that the names of these members match the names of the properties on the main type.
Also, even if this exception did not occur, I expect to get into even more trouble with model validation on form submit because Password is marked as required in my business entity.
I can think of several workarounds, but none seem really ideal. In any case I can't change the database layout so that the password field would be in a separate entity in my example above.
How would you handle this scenario?
