What's wrong with VWD express?

Injecting Lower Layer Dependency In Presenter In MVP Application?
Jan 27, 2010I recently read Phil Haack's post where he gives an example of implementing Model View Presenter for ASP.NET. One of the code snippets shows how the code for the view class.
public partial class _Default : System.Web.UI.Page, IPostEditView
{
PostEditController controller;
public _Default()
{
this.controller = new PostEditController(this, new BlogDataService());
}
}
However, here the view constructs the instance of the BlogDataService and passes it along to the presenter. Ideally the view should not know about BlogDataService or any of the presenter's lower layer dependencies. But i also prefer to keep the BlogDataService as a constructor injected dependency of the presenter as it makes the dependencies of the presenter explicit.
This same question has been asked on stackoverflow here.
One of the answers suggests using a service locator to get the instance of the BlogDataService and passing it along to the presenter's constructor.This solution however does not solve the problem of the view knowing about the BlogDataService and needing to explicitly get a reference to it.
Is there a way to automatically construct the presenter object using an IoC or DI container tool such that the view does not have to deal with explicitly creating the BlogDataService object and also injecting the view and service instances into the presenter's constructor. I prefer to use the constructor injection pattern as far as possible.
Or is there a better design available to solve the problem?. Can there be a better way to implement this If i am building a WinForms application instead of a ASP.NET WebForms application?

Architecture :: Use STATIC Methods In Data Access Layer?
Feb 4, 2011I am developing a web application, which has Data Access Layer and this layer has only one class, in which all methods are static methods like static Insert, static Update, static Search. It has no properties. I am using these methods in my Bussiness Logic class for my users who are visiting my website.Now my question is : 1. Is it right to use static methods in this scenario ?2. What will happen if 10 users call Insert method at the same time ?

Architecture :: Data Access Layer And Business Logic Layer?
Jun 24, 2010I am building a web site following the tutorials on asp.net. I am using dataset as data access lay, and writing classes to access the dataset. But the example is just basic ideas, how do I retrieve individual table column value in the business layer?For example, if I have a table called Product, I only want to find out what is the product name by product id. I did this in my ProductBLL:
public ProductBLL
{
public int GetProductName(string productId)
{
ProductDataSet.ProductDataTable prodData = Adapter.GetProductById(productId);

Is there a better way, or am I doing this correctly? Can anybody give me a reference to a more complicated business logic model?

View 2 RepliesMVC :: How To Make Business Layer Seperate From Presentation Layer
Feb 23, 2011I've even got my JQuery Ajax submission going on now but I've encountered another problem. I *think* it's something to do with the structure I'm using but like I say, I'm fairly newo this.I have my AJAX form submission which builds my "PersonViewModel" (model for the presentation layer) in JSON and sends it to "@Url.Action("RegisterSubmit")" in my Person Controller. Now, I seperate my business layer from my View/presentation layer so in "RegisterSubmit"I'm verifying the model is valid then instantiating a new instance of my business model "Person", adding the values from "PersonViewModel" and then calling my "Save" function.
View 7 RepliesBusiness Layer Errors And Service Layer Handling?
Mar 7, 2011We're building a large web app that has numerous layers. In order to communicate to the business layer we're using a service layer that the web layer calls when data is needed. Unfortunately, it seems that if exceptions are thrown in the business layer, it seems that the services on the web side are wrapping the exceptions and re-throwing them. We're looking for a clear way to encapsulate the error and log it, without WCF wrapping a new exception around the original.

Web Forms :: Drop Down Menu Causes Lower Divs To Vanish?
Jul 24, 2010I have created a horizontal menu using <UL> and <li> tags. Hovering over a top level <ul> causes the lower lever <li>'s to drop down. This works well but there are two narrow <div>'s below that act as decoration. These disappear when the drop down submenus lay over them. I have played with the z-index properties of both lower <div> and of the menu items but have not resolved the issue. I want the submenus to drop down over the <div> but for the <div> to remain visible outside of the covering sub-menu.

C# - N-layer Business/service Layer Design?
Jan 26, 2011I'm trying to reevaluate our n-layer architecture and would love to get some based on your experiences. Here is our typical .NET n-layer (sometimes n-tier) design.
Project.UI
Project.Services
Project.Business
Project.Model
Project.DataAccess
DataAccess typically consists of Entity Framework 4 and Repository classes. I attempt to follow the Aggregate Root concept in order to avoid having a repository for table, easier said than done in my experience. I tend to have ~70% match between Repositories and Tables.
Model usually consists of my Entity Framework 4 entities, I've been using Self-Tracking EF entities with success.
Business is what I struggle with the most. I typically have a Manager class for every Repository. This class will contain methods like .Add() which will perform business validation before forwarding down to repository.Add().
Services, typically I will only implement this if in fact I am looking to create a web service based solution. This layer will be tasked with marshaling requests/responses between DTOs and entities. And most importantly provide the more coarse grained interface. For example a TradingService.SubmitTrade(), which is really a facade for a business transaction which might include AccountManager.ValidateCash(), OrderManager.SubmitOrder(), etc.
My business layer is very entity centric, really it's just the glue between the entities and the repository, with validation in between. I've seen many designs where the Service Layer is what holds a reference to the repositories (in essence skipping the "business layer"). In essence it serves the same purpose as my Business layer, it does the validation, however its' responsibility (and naming) is a higher level, more coarse grained business transaction. Using the example above the TradingService.submitTrade() will not delegate to any business manager classes, it would itself query the necessary repositories, perform all the validation etc.
I like my design in a sense that I can reuse a business layer method in multiple service calls, however I hate the fact that for every repository I have a matching business layer manager, creating tons of extra work. Maybe the solution is a different type of grouping at the Business Layer level? For example combine individual Manager classes like PhoneManager and EmailManager (note I have Phone entities and Email entities) into a logical Manager class such as ContactsManager (note I don't have a "Contact" entity type). With methods such as ContactManager.GetPhones() and ContactManager.GetEmail(), etc.

In order to standardize the ID's of all html elements I want this to be lower case. Rather than specifying the ID manually - which won't get updated if I rename my property, I'd like to establish a convention. I'm sure I read this was possible somewhere and I'm currently scanning the interwebz to find it.
