In some of the classic descriptions of MVC, the Model notifies Views via the observer pattern. It seems to me that this doesn't happen with ASP.NET MVC, and so one of the fundamental relationships between Model, View, and Controller is missing.
Is this the case? If so, why?
I have following architecture. My Model:
[Code]....
The partial view "PersonsView" has the same model and looks like this:<%@ Control Language="C#"
Inherits="System.Web.Mvc.ViewUserControl<Web.Models.WebModel>" %><%Html.RenderPartial("Person", Model.Persons.First); %><%Html.RenderPartial("Person", Model.Persons.Second); %>
And the the partial view "Person" has an other model:[Code].... If I press the "Submit-Button" on the first view I get to the follwing controler: [Code]....
I'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.
<p>Hi</p> <p>I'm a newbie in MVC but a veteran web forms developer. I really like the idea of strongly typed views but what if I have multiple objects to pass to my razor view. Would I then NOT use strongly typed views and just use the ViewBag?</p>

I have recently updated a website. All of the urls have changed. Now I get traffic to old urls that doesn't exist anymore. However, most of these url's have corresponding pages on the new site. I believe most of the traffic to the old urls are spiders. What would be the correct way to handle this?
Preferably I'd like a solution that gives a nice experience for the real users if they type in an old url (or use an old bookmark they've made) but that also notifies the spiders of the change of url, so that they can update their registers. However, if the two are hard to combine, the last one is prioritized (since most of the traffic is spiders). I'm using ASP.NET
I have a web form for a user to update their user information. I have an ObjectDataSource configured to use the Update method in my BLL. If the user changes their email address in the web form, the BLL Update code checks to make sure the email address is not already in use. If it is in use, I want to cancel the update and notify the user.I was going to raise an ApplicationException in the BLL and catch it in the web form code-behind, then present a message to the user. But from what I read, this is bad practice: http://blogs.msdn.com/b/kcwalina/archive/2005/03/16/396787.aspx

I am learning MultiView control.Here are question:I added 5 views in the MultiView but all views are tight together. I can not drag and drop another control such as text boxes or labels into view area.
View 15 RepliesI have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,

How do I have the model binder creates 2 model, or should I have one combined model?
I have been searching for this answer and can't seem to find anything, but with EF4 I want to create a base model and put in our 'foundation' and any new project we create if we need to add custom tables to that sites db is it possible to add a model with just those specific tables and link it to the model in our 'foundation' I can't seem to find a good resource on something like this and this seems to be like it would be a normal thing to have a reusable base model and a separate one for any one off's

I created a model via adding an ADO.Net Entity Data Model (.edmx file), which brought in all my tables from my database. Is it possible to add validation attributes like [Required] or [Display] to a model created like this? Otherwise, the only alternative I can see is to hand-create a model class with public properties where I can annonate them with the attributes I need.
View 2 RepliesI want to use RenderPartial twice in my view with different models associated. The problem is that some properties are present in both models (nickname, password).

I'm trying to develop my application and I've got a master page where I'm planning to create a div container, where my "news" will be loaded from my database and will be shown always on a main site. Then inside of the main placeholder I'm planning to load some extra data too from my database... and there's the question: how to solve that ? is there any possibility to pass a model to a master page ? or two viemodels to a view page inside the main placeholder on my page ? (one with news, and other containing some other data).
View 4 RepliesIs it possible to do something like this?

I am trying to use both models in my page.
I've half written an app which has just one model for adding and editing a particular entity.I am trying to embrace modelmetadata and where possible reduce my form code to just calls for EditorForModel. One of the key issues I am having it managing the
differences between a add and update scenario.
Take "User" editing for example, in an Add scenario I want "Password" to be a required field, in an update scenario I dont' want it to be a required field. The model-centric approach would have me create two models, one for adding and one for editing. My
edit model wouldn't have the Required attribute on the Password field. My feeling is this is going to create a bit too much plumbing.
Besides having a rather massive amount of automapping going on there is another more irrititating issue. Strongly typed views. I could... maybe see my way to having a different model for create and edit, using inheritance i could.. maybe mitigate the amount of code required. What I can't abide is having to have two seperate views, as I have already coding myself into a wall with strongly typed views I couldn't share add and edit (based on my understanding) scenarios with one view.
So anyway I was wondering what other peoplle are doing to manage this? Working with an outsourced (Indian) developers it would be great to make use of EditorForModel as I want them writing as little code as possible.
I've a product model that contains a list of description models. Every description model contains some string values because every product can have a description for every language. Here it is a semplified version of my models:
[Code]....
So my view to insert a new product is like this:
[Code]....
And my PartialProductDescription view is like this:
[Code]....
Now, the views are perfect. With some Jquery UI I have a form with all the product properties and a tab panel with the language descriptions.
Unfortunatelly my POST action with the firm public ActionResult ProductNew(ProductModel model) has all the model property InternationalDescriptions that contain 2 empty models. So if I write something in the form in the first description textarea, model.InternationalDescrtiptions[0].Description is always empty.
So, how I can tell to MVC to take description textarea values and put them in the model?
