I have a facade class that my controller class calls out to and in that facade class, for whatever reason, I'm building a string a href element. And it resolves fine in casini but when it gets out in the real world like localhost it doesn't work. Is there a way to do this?
string goBackLinkForErrorMessage = "<br /><a href='/MyController/Action?id=" + blah + "'>Go Back</a>";
I'm trying to create an XmlReader class instance to read an xml file. However I pass it a url for the xml file but it isn't resolved. what do I have to do to get the proper url?

my MVC2 delete and only my delete controller is refusing to return any class information. Its really similar to my edit function and the views are all auto-generated so I don't see the problem.

I'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 RepliesI have an MVC2 application with the following classes:
-OrderModel
-LineOrderModel
-OrderController
-LineOrderController
In the OrderController class I'm recollecting some values of a web form . Until now, I created instances of each order line (LineOrderModel class) and OrderClass inside of the Controller.
I was trying to create a OrderFacade class in order to encapsulate the different things to do when creating an order.
So in that class I created a method like this:
public void saveOrder(int idProvider,decimal? price)
{
// Here I create instances of OrderModel and LineOrderModel
// and assign their properties
}
but my problem is I don't know how to pass all the order lines captured from the web form.
I think it doesn't make sense to create and pass to that method a List with orderLines class (because the point of this is to operate with the Facade, not with the class directly)
How could I encapsulate the different lines (all with properties like numberUnits,idProduct ...) into a List of generic objects, each one with these properties?
Maybe something like a List<List<object>> ?

View 13 RepliesI just started working on one of the application, bascially its some maintanence work. I see from the application that Facade pattern has been utilized as I see Class Library projects named as Business Facade, Data Facade.
Though I am not redesigning this, but just wanted to know what this pattern is, a simple explanation, use, real world example should be good enough. The application is basically a banking app. I know its diff but if anyone can give me some hints/points as in why the designer chose this pattern (banking app).
Is there any way to convert our class to controller in asp.net MVC ....

I 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.
I doubt how to implement the layers
FACADE, BLL and DAL, using
DTOs specialized ..
where:
public class ClassA
{
private int _Test1;
public int Test1
{
get { return _Test1; }
set { _Test1 = value; }
}
}
public class ClassAB : ClassA
{
private int _Test2;
public int Test2
{
get { return _Test2; }
set { _Test2 = value; }
}
}
public class ClassAC : ClassA
{
private int _Test3;
public int Test3
{
get { return _Test3; }
set { _Test3 = value; }
}
}
In the database, there is the 3 tables, as described above.how do I implement the facade, bll and dal? only one class for 3 DTOs?
which one is better in "Session Facade Class" and "Singleton Object" design patterns in ASP.Net? Also, please state the scenarions where specific design pattern is advisable to use.
View 1 RepliesI am having problems adding a reference to a custom assembly in my Bin folder within a controller class I am writing. I can see the dlls in the Bin folder of my Solution file and when adding a new 'using' block to the top of code page, its not picking up any of my assemblies as I try to spell them out.I tried just typing them in and building the solution, but I get errors, it just wont pick these up!
View 3 RepliesI 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.
I'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.
Assume the current executing action method is Index() in Home controller. From within Index(), how to obtain the physical file path of the Home controller? Assume we don't know the file structure until runtime.
View 2 RepliesUML 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.

In my web application I am using NHibernate.dll. This has a dependency on folowing assembly.
'Antlr3.Runtime, Version=3.1.0.39271,

Now in the same project for another requirement I have to introduce Antlr3.StringTemplate.dll. Which has a dependency on another version of the above assembly.
If I use the version of Antlr3.Runtime.dll which satisfies NHibernate , Antlr3.StringTemplate starts complaining and vice-versa.
I am currently localizing my MVC website, using the Html.Encode method.
I've got a global resouce named "Localization" and using it by e.g. <%= Html.Encode(Resources.Localization.FirstName) %>

myControl.Controls.Add(myLink);
I want to be able to resolve the myLink.NavigateUrl at run-time according to the context that myControl puts the control into in the end (this is not a WebControl and therefore adding to the collection of controls doesn't output to page).
