MVC :: Type-Sensitive Display Of A Model?
Sep 16, 2010
Say I have a Form model which contains a list of Field objects loaded from a database. Each field object has a type that defines whether it is a listbox, combobox, input or textarea.
What would be the best way for displaying the Field objects correctly? I was thinking in my View using a switch statement and calling a specific partial depending on the case.
[Code]....
Is this a valid approach? What other methods would people recommend to do this?

I have a need to show sensative information but I would only like it available on screen for 2 minutes, and then after it dissapears.
Since this is part of my web application, I would like the user to stay logged into the web site before and after viewing the information, but in order to view it, I would like them to re-enter their username/password.
Are there any directions I can be pointed into accomplish this task?

I know that the code depicted below will not work but I am including it to convey the idea of what I wish to accomplish. I want to use a different SiteMap to construct the menu on the displayed page for each of three different classes of service (COS).
I set a session variable named "COS" at the login and want to test its value prior to rendering each page. I want to display a menu based upon the appropriate COS. Here is my first stab at it but I know that I cannot include <asp:...> controls within the "case" statements. Can anyone suggest methods of doing this? I know C# and can use that but I do not know how to select the proper sitemap within the <menu> control. I am also using a CSS in my production version.

I have some questions in my mind after went through the video tutorials.
Is Model a entity class type? encapulated attribute and methods (business logic). because i see in videos , people use LINQ to generate models which can only use LINQ to modify/insert/delete data.
Is it a good practice to generate Model using LINQ?

i having error throw on View page and i think i am passing wrong type.
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[App.Domain.Model.Interface.IPerson]' but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[App.Domain.Service.PersonService]'.
MyService looks like this....

When i loading modules from different places i injected them to controller factory, but when it is trying to load strongly typed views it can't find model type that is contained in module assembly.I made new ViewEngine and now it looks in right places but it cant load strongly typed views.
So as i understand i need to show the view where to find class model. If you have any other ideas please tel me. And one more i need this problem to be solved for WebFormViewEngine and RazorViewEngine.

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)

but 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.

Normally I work in ASP Classic, and am still a bit green on ASP.Net MVC.
I have my model with its fields or entities (might not be the right word hence why not able to find if previously answered, forgive me), and some of these will have null values such as hyperlinks, email address, specific types of phone numbers, etc.
What I want to do is not write certain blocks of HTML within the foreach loop if a field is empty.
In ASP Classic, I would have written an If statement along the lines of:
<% If RS.field <> NULL then %>HTML with <%=RS.field %><% End If %>
<% If RS.field2 <> NULL then %>HTML with <%=RS.field2 %><% End If %>
...
However, I don't know how to achieve the same result in ASP.Net MVC.In one of my current usages, a list of sellers returned for a specific set of search results, it runs through a foreach loop and returns the current HTML (in part):
Website: <a class="url" href="<%= seller.ContactWebsite %>" target="_blank" title="Visit the website for <%= seller.Name %>"><%= seller.ContactWebsite %></a><br />
So, if for example I have a field from the model, say seller.ContactWebsite, and this field was NULL, I would not want it to write this as part of the foreach loop.

I am a MVC newbie & am lost in various ways validation can be implemented in my application.
I created a custom model-level data annotation validator attribute, but am unable to display its error message in the view. Basically, I have let's say 5 properties in the Entity class Job (model-level custom attribute called UniqueKeywords defined on it):
1) LoginID: value comes in the URL
2) Title: Required property level attribute defined on it
3) CatID1, CatID2, CatID3 - 3 categoryIDs - these are dropdowns in the view with same list of keywords in all 3.
I want to mandate that the values picked by the user in all 3 category dropdowns should be different.
With reference to the code pasted below, here is the explanation of what happens:
When I submit the form without specifying a title or picking anything from any of the 3 category dropdowns, the validation occurs for the property level Required attribute as well as model level uniquekeywords attribute, but the error is displayed only next to the required field "Title". I can confirm that the custom validation also works by filling in some text in the Title field & then re-posting the form...this re-displays the view, but the error message "Category cannot be duplicated" is not displayed.
Only relevant code sections are pasted below:

This is my first time working on a secure website. It's for a pet project I have.
For security purposes, where is it best to store information like SQL connection strings, database encryption keys, etc? Is it better to use web.config, store them in a class that accesses a database (like dataBaseHelper.cs or something), or somewhere else?
I intend to obtain an SSL cert as well. When communicating with the database, should I always use the secure connection?

I am using ASP.NET 2.0 and C#. I would like to know if the Session variables are Case-sensitive.
Is Session["StudentId"] and Session["StudentID"] considered the same.
Which would be the proper way to access the session details, when in a page someone passes data as Session["StudentId"] and somebody else passes as Session["StudentID"]?

Trying to figure out the best way to organize a ASP.NET MVC site. Take a very simple 1..N relationship: Company can have many Contacts, Contacts must have exactly one Company.I have your typical routes:
Company/Index (list all companies)
Company/Details/{int} (details of Company {int})
Company/Create (create new company)
Contact/Index (list all contacts)
Contact/Create (create new contact, company is selected from drop down)
Now if I wanted to create a page that created a Contact in the context of a Company (from the Company detail page) so that the required company is filled in/not editable), what would be the best route of going about that, while not duplicating code where possible.Not sure if I can leverage the Contact/Create logic/view from the Company controller (and be able to route back to the Company Details page when complete), or mess with the routes to do something like Company/Details/{int}/Contact/Create (not even sure if that makes sense or would work)?There has got to be a better way then me adding my logic and view for adding a Contact into my Controller view and having it duplicated.

I'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?
