Parent Controller Class In .NET MVC 2?
Jul 26, 2010I've been working on a rather large web application that requires a specific id param in the url for every page visited (for example, /controller/action/id?AccountId=23235325). This id has to be verified every time someone visits a page. want to reduce code replication as much as possible, and was wondering if there is a way to use an init method or constructor in a controller that inherits the MVC controller, and then have that controller extended by the others.

View 1 RepliesImplement Cross-session Data Controller Class?
Feb 24, 2011I am creating an ASP.NET application that allows users to edit and insert data that is persisted in a SQL Server database.I would like to implement a controller class that handles queries for certain entities, caches results and triggers events when data is inserted or updated.I need one of these controller classes for each entity in my data model.What I'm unsure of is how to create a singleton class of this sort that different user sessions can access.
For example,I have a Employee entity in my data model.I would like to have an EmployeeController class that handles retrieving the employees from the database, sends inserts and updates to the database,keeps a cache of all employees and triggers events when an employee is inserted or updated.Objects in other user sessions could then listen and respond to these events.
Am I on the right track?Should I be using the ASP.NET MVC framework to accomplish this?How do I instantiate these controller classes when the first user needs them and have subsequent concurrent users access the same class?
EDIT:I've been researching the idea of a controller class as an anti-pattern since @TomTom's answer.I'm not convinced one way or the other.I still need an answer to question #3 above.Let's just drop the specific idea of a controller class for now. How do I create any class that is:accessible by multiple user sessions,allows only one instance,is deleted if there are no user sessions,and triggers events that other classes can listen to.

View 3 RepliesMVC :: Access HTTPContext And Session From Custom Base Controller Class?
Jan 13, 2010I built a base controller class inherits from Controller class to add some custom behavior to all controllers which will inherit from this base class.
My issue is when I try to access HTTPContext and Session objects in my custom base class, they are always null.
Am I doing something wrong or need missing something?
My custom base class definition:
public class ApplicationControllerBase : Controller
controllers classes definition:
public class HomeController : ApplicationControllerBase
using ASP.NET MVC 1, .NET 3.5.
UPDATE:
It seems the issue is I try to access HTTPContext in the constructor while HTTPContext is not ready yet, I tried it in the OnActionExecuted event handler and it works fine.
My question is what is the best place to access Session object in my custom controller class, that will guarantee executing my code with all controllers.
MVC :: Controller Base Class Initialize() And OnActionExecuting() Not Called When Unit Testing?
Nov 16, 2010I'm using a simple base class for my controller that sets a piece of ViewData and makes use of the HttpContext. My understanding is that I need to put this code in Initialize() or OnActionExecuting(). I tried both, but believe Initialize() is what I want.
This works when running the app in VS just fine.
I wrote a unit test that calls the action and checks the ViewData for the expected value. When unit testing, neither method is called.

Dec 28, 2010UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.
View 1 RepliesMVC :: Controller Method For Create Not Working
Oct 27, 2010I'm very new to MVC so this is a simple issue, just can't seem to find any information on why it's happening so turning to the forums. Edit works, delete sort of works (that's another issue in itself), and details works, but create causes an issue. I've debugged the form being passed in and it's always null with default values. It's almost identical code to my edit so I'm not sure why edit works and create won't. I'd show code for the view but since it's working for edit I'm currently ruling that out as the problem. "Colleges" in this populates a dropdown in the view. Here's the code:

MVC :: How To Create A Controller And View With Data Coming From Seprate Tables Associated With Foreign Key
Mar 8, 2011I am using Entity Frameowrk as the ORM. I am new to MVC and trying to develop a samll module as a learning project.
Now I am stuck with an issue for which I can't seem to find out answer on web. The issue is :
I have two tables mapped as entities - Tenant_Definition and Contact
Tenant_Definition { Tenant_ID , Desc, Contact_ID}
Contact {Contact_ID, Company_Name,Company_Address,Person_Name, Person_Phone_Mobile}
My View has to present a form that shows Tenant Desc and Contact related fields. The index view works fine and shows the desired values.
But, the create view isn't working out. In the create view, i am planning to do -
1. creating a new contact entity instance and saving it in db
2. Then creating a new tenant entity instance using the new contact_id and save it to the DB.
However, the code doesn't seem to be inserting any value inside Contacts table. It inserts null value.Below is the code snippet of my Create Controller -

Create New Class For Each Procedure?
Jul 23, 2010All I want to do is learn how to create a class procedure. And then. How to call it. As an example, A + B = C is the procedure. I would create a class. Right? Then do I name the procedure and put it in the class? Or create a new class for each procedure? Then I would want to, on a local level, substitue values for A & B to return C. So, if the public procedure exists, how to I call it? I know that this is really simple stuff, but I need examples to be simple.

C# - Cannot Create UserControl In Class
Jan 26, 2011My ultimate goal is to create a UserControl in a class in my App_Code folder and render the html from that into a string.
The rending of HTML can be done using this example I believe:
How do I get the HTML output of a UserControl in .NET (C#)?
My Question:
I created my user control
public partial class Controls_MyUserControl : System.Web.UI.UserControl
I've registered it in my web.config
<add tagPrefix="UC" src="~/Controls/MyUserControl.ascx" tagName="MyUserControl" />
I can reference this on a page just fine
<UC:MyUserControl ID="MyUserControl1" runat="server" />
Yet when I try to create an object of this control type in a class (in my app_code folder) it doesn't allow me.
Controls_MyUserControl dummy = new Controls_MyUserControl();
The potentially strange thing is when I put this code into a code behind of a page, it works.
what I need to do to have the usercontrol to be able to be created in my class in the app_code folder?
My guess is, is that I need to reference the control in a "using" statement at the top, but I'm not sure what that'd be.
It's not in a namespace to my knowledge (at least there's no namespace, in the code behind of the actually user controls). Though I'm not sure if it inherits one from the System.Web.UI.UserControl.
