Setting A Default Value -- Presentation Logic Or Business Logic?

Jun 18, 2010

I was wondering if setting a default value for a SelectList is considered to be presentation logic or business logic? For example, if a requirement is that an Employee cannot be saved without a Location, but 99% of the time the location that would be selected is a particular item -- say Atlanta. Because of this, the location SelectList should be defaulted to Atlanta when ever a entry screen for a new employee is displayed. Should I be defaulting the location in the model or in the view-model? One thing I realized is that the unit tests become awkward because in both cases, I'd be forced to test against a location that will always be present in production but I cannot create a unit test with my own test dataunless "Atlanta" was in the set of locations being used in the test.

MVC :: How To Use Business Logic

Nov 21, 2010

I've got a C# MVC 2 application using EF 4. My DAL project gets data from the Model, translates them into POCO's and returns ViewModels to the BLL which is called from the controllers.I've set up validation attributes on the POCO classes and that works for "Required" fields etc. I would like to add business logic such as "From" has to be before the "To" date. Can this be done on the POCO classes so it is automatically validated client-side in the view?

Also, I would like to add some functionality to the BLL layer such as checking if a resource is already booked between the From and To dates to avoid double bookings. This should fire before the ViewModel is saved. I tried a Try/Catch statement in the controller so that I can throw an error in the BLL, but I don't understand how to return this error to the view with an appropriate error message added.

Business Logic Not Exposed On Formview

Oct 16, 2010

I have to maintain an ASP.net application in VB.Net. There is a page with a FormView bound to a ObjectDataSource. I have to add some business logic on the ItemUpdating event of this FormView. Unfortunately, some the data that I need to add this business logic is not exposed on the FormView user-interface itself, so I can not use FindControl to get the values (I could add the controls, bind them to the fields I need and set their visible property to true, but that's ugly).

So, what I would need to do is to get access to the Data Row corresponding to the currently selected item in the FormView from the code behind as it has the data I need to add my business logic code. Unfortunately, I don't manage to get access to the row.

Implement Transaction In Business Logic Layer?

Jan 17, 2011

I'am using enterprise library data access block in my asp.net application. I want to implement transaction from the Business logic layer, across multiple stored procs. Entlib opens a new connection for database access. Does using Transaction Scope in the following way lead to distributed transaction?

using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
{
// calling necessary DAL methods
scope.Complete();
}

Is there better methods to implement transaction from BLL?

How To Separate Business Logic And Database Calls From A WCF Web Service

Jun 3, 2010

This question may have been asked before, but I'm looking for a different answer than what I've seen.

Our website is in ASP.NET and we use the model-view-presenter pattern to get business logic out of the markup codebehind.

Is there an accepted pattern for web services for getting business logic out of the codebehind? It seems like putting the logic in a 'presenter' is misleading since the calls don't really present anything to the user, and may not even send back data to the client.

MVC :: Calling Business Logic In Model From Submit Tag In View?

Jun 30, 2010

Currently I am working on a project at work that deals with MVC. I have never used MVC before, only dealt a little with ASP with VB, and that's it. I've dabbled in HTML but not much. I don't currently have the money for a book, so I'm using this forum. So there's a lot of jargon I may not pick up on or may ask a lot of questions, so please bare with me.Anyways here's what I would like to do, or understand. We're using ASP.NET Membership Security (not sure if that's what it's actually called) for passwords and accounts. My issue is that I've been working on other projects while the rest of my team has been working on this, so they know more about it than I do. And I don't want to take too long to understand it, but I have to find the best way to make sure the following doesn't happen:

1) When changing a password, it can't be within the last 10 passwords used for that user.2) When creating/changing a password, it cannot have dictionary words, names, phone numbers or personal data within it.3) The password must be a minimum of 16 characters.Number 3 is rather easy and completed I believe. However, 1 and 2 prove tenuous. We want to store the previous passwords hashed and we were going to save the salt used. However, I'm beginning to think that with the Membership class you can't specify the salt to hash a password. Is there a way to de-hash a password? We do not want to store the passwords as plaintext, so that is out of the question.I believe the best order (for 1 and 2) is to do 2 first (before it's hashed) and then 1. For two, I need to know how to call a function in the Model code from a <submit> tag in the View code. I've done a little research online but thought I'd ask and see if it gets answered while I'm looking for the answer.

In general, my questions are:1) How do I call a function in the ****Model.cs from a <submit> tag in the *******.aspx?2) What's the best way to compare previous passwords that are hashed? 3) If I know the salt, can I de-hash a password? (I believe the answer to this is no.)4) Can I specify the salt to hash a password? (I believe the answer to this is no.)5) If #3 and #4 are no, then should I do encryption instead of hashing?Details: MVC2, C#, Membership.

Classic ASP App Has COM 'middle Layer' For Light Business Logic?

Oct 19, 2010

I am trying to estimate how long it will take to migrate a Classic ASP application to .NET and came across hundreds of COM functions written in VB 6.

A majority of these functions only do parameter validation and actually calls the SQL server. Is this something that should be replace with an ORM? (Linq, nHibernate, Entity Framework)... or should there be more to this picture?

MVC :: Using EDMX And A 'business Logic' Class To Form The Model?

Jun 4, 2010

This not an 'MVC' question per se, but this is the closest forum I could find. I am building web/wpf/silverlight front end on the MVP pattern. I am using EDMX and a 'business logic' class to form the model, a presenter project, and a view project.The IViews contain the basic structure of each entity, the presenter contains actions, etc.Sample view:

[Code]....

Sample presenter:

[Code]....

QUESTIONS:I seem to end up with a 1-1 mapping of views and presenters. SHould there be more than one view per presenter, or more than one presenter per view? Should the presenter for an entity (in this case a User) also contain methods for functional items such as searching for a filtered list of Users using overloaded methods, etc.?Should the IViewXYZ interface contain any events or actions (methods)?

Calling Business Logic Layer Method From PageMethods?

Jul 12, 2010

I've a static page method in web form application and I want to call method on private class level variable from it as shown below. I'm using jQuery to call the page method.

private readonly ICatalogBLL _catalogBLL = new CatalogBLL();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
_catalogBLL.GetSomething();
}
}
[WebMethod]
public static UpdateSomething(int i)
{
//Want to do as below. But can't call it from a static method.
_catalogBLL.UpdateSomething();
}

UPDATE If I call it as said by John Saunders, won't it use the same instance for requests from different users as it is within a static method?

Architecture - Removing Session Calls From Business Logic?

Feb 4, 2011

I've inherited an asp.net web solution, which has business logic and data calls as seperate assemblies. In the business layer there are a small number of calls to get/set HttpContext session values. I've looked around for an example that will allow me to abstract this away from the business logic as I'd like to be able to reuse these assemblies in non-web projects, could anyone please give me an example of the best way to do this. I was thinking of some sort of session factory that will obtain values from some sort of persistant store depending on the usage scenario but I'm new to architecture really and would appreciate a pointer or two.

Web Forms :: Exceptions From Business Logic Layer Not Caught In Application_Error?

I know there are a few posts on this issue already, however I haven't found the answers I was really looking for.

My situation is like this: I have a DLL project containing my business logic. Then I have a web application that refers to this DLL, and calls a function from it. And I have a global.asax which handles errors on Application_Error

Sample:

// MyWebsite.aspx.cs
using MyBusinessLogic;
protected void Page_Load(object sender, EventArgs e)
{
MyBusinessLogicClass.DoSomething();
}
// global.asax.cs
protected void Application_Error(object sender, EventArgs e)

Forms Data Controls :: How To Repopulate Insertitemfields When Detailsview Insert Fails Sql Business Logic

After hitting the insert button the insert stored proc is run. if the record already exists then stored proc returns a specific value.I need to refill the details view textboxes with the values the user typed in.I am using the ItemInserted event handler.I seem to reference the control okay but the text doesn't change...even when I replace the command.parameter to just a literal text like "test".

TextBox tNPA = DetailsView1.FindControl("InsertName") as TextBox;
tNPA.Text = command.Parameters[0].Value.ToString();

So what am I missing. I also tried a detailsview1.databind() before and then tried after the above line and still no luck.

Architecture :: Data Access Layer And Business Logic Layer?

I 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?

Here is verbatim what ASP.NET MVC 2 Release Candidate Release Notes says:

"...Buttons in a form can specify that they do not cause validation logic to run. The default is that every button in a form causes validation logic to run, and if validation fails, the validation logic blocks submission of the form. Enabling validation selectively for buttons lets you create forms .
