Is it possible to do something like this?
Inherits="System.Web.Mvc.ViewPage<List<SectionAdmin.Models.ADirectory>>, <List<SectionAdmin.Models.BDirectory>>"
I am trying to use both models in my page.
<%@ Page

Inherits="System.Web.Mvc.ViewPage<JCIOrange.Models.UserProfile>" %>
How do I display more than one model per view? The above line limits me to only display UserProfiles. I want to also display other models, like UserJob and etc....how would I go about doing so?
I am having two models User and Address. In the create User view apart from the user information, the user can add one or more addresses to himself. So is there a way to do model based validation for multiple models in the same time ?
View 9 RepliesHow do you handle multiple models in a view?. I have 2 tables. Member and MemberAddress
Member class contains Collection of MemberAddresses since a single member may have a billing and shipping address:
public class Member
{
public virtual int MemberId { get; set; }
public virtual string Username { get; set; }
public virtual bool IsActive { get; set; }
public virtual bool IsSame { get; set; }

I'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.
I know that view model can be used for rendering a view, but if a page needs different models, how can I pass them to the view? And how do I use them?
View 2 RepliesI have a parent View that uses a few partial views. Each partial view has its own custom model. The parent View is a model containing each of the partial view's model. In other words this parent View model is NOT flat.
How do i get POST data to bind with the parent's model object? Do i have to write a custom model binder?
Update I'm not binding to a collection of objects of the same type (ie: a collection of uploaded files). I'm binding to object that contains multiple of objects. For example:

(Using SQL Server 2008 and ASP.NET MVC2)I have a simple business table and a category table. I have a 3rd table to map business to category, a many-to-many relationship. the Map table contains a BusinessID and CategoryID. I'm lost as to how I can load the categories into my Business View Model using the entities model.Without incorporating categories, my code looks like this:

with Business View Model defined as:

but if i want to populate the Categories with the mapped categories, how would one do that?
quick 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.

So 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.
I have used multiple grid view on same page with multiple selectedindexchanged event but selected indexchanged event call only for first gridview.

I 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:
[Code].........................
I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?
View 2 RepliesI'm planning to make a page that has about 10 different pages for varying use, for example, stats, data entry, reports, logistics, audit, sales, promo, etc etc. I'm anticipating there will be many combinations as to what pages a user may have access to, for each page, a user ought to be authorized to either enter new data, edit data, print and/or just view.
My questions are :
1. can membership & roles be used, once user is logged in, to display links to all the areas of the web app he is allowed access to?
[code]....
2. besides having access to a particular page, a user should, as mentioned before, be authorized to either enter new, edit, print and/or just view data.
3. Is there a preferred/better method to handle this besides using membership & roles?
I am doing a registration form where the user enters his account information, and some other misc. information.
The misc. information are stored in another table and hence has its own model.
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
View 1 RepliesI 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 4 RepliesIn 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.

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.
