Web Forms :: Mark Up A Database Driven Table From Custom Business Objects?

Apr 14, 2010

UI markup to create the table shown below, which I have mocked up quickly to visualise what I need to do. The data is in the form of custom objects; a SelectedSession object which has a List (Of Students) sorted by AcademicYear, TeachingSet, then name.

So the question is how do I create that table from my custom object?

<table class="style1">
<tr class="academicYear">
<td colspan="3">

Dynamic Data Be Made To Work With Custom Business Objects Rather Than Data Objects?

Feb 24, 2010

I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?

C# - Can Improve Business Layer Objects Mapping Into A Database

Sep 2, 2010

As I began writing web applications with asp.net I started with small projects that used a Linq-To-SQL mapper for database access to a MSSQL Server. After gaining some expierence I switched into a classic 3 tier with Graphic Layer, Business Layer, Data Layer. The only function of the Data Layer was to provide methods insert/update/delete without any logic and logic the form of selection methods.

Over the time I realized that it would be better not to provide the database classes up to the GUI (took some time unfortunately). I switched into using Business classes in the BL that are used for all operations performed by the BL and display by the GUI in the form of getting List from the BL. A great advantage is that I can provide additional properties that are not represented by the database itself. However, I did that mapping inside the BL myself with methods that mapped the corresponding BL class to the database class.

I guess thats where O/R mapper come in handy? Until now I haven't realized their purpose, but I think I just found it. I've recently tried out using the new Entity Framework with .net framework 4, but I'm only using it like the Linq-To-SQL DataContext.

Is there a way to achieve the mapping automatically? If yes, is that something the new Entity Framework provides or do I need to look for a O/R Mapper like NHibernate?

Architecture :: How To Design Business Objects

Mar 20, 2010

designing Business Objects. What a business object class can contain ?

I have looked many sample codes and articles. Some only use properties in them. Some use private members, properties and constructoers. As more I am reading becoming more confuse.

Some sample codes that I checked were making functions in BO classes as well. what a BO class should contain and what is its purpose. Should there be functions in them as well ? If yes how they can be differentiated from Business Logic class functions.

Architecture :: Maintaining Business Objects ?

Feb 2, 2010

We are using below class(TypeInterceptor) in one of our project to create the instance of business objects.

To Create any business object, we are using the below code


BLayer.TestBO objTestBO;

this.objTestBO = TypeInterceptor.CreateObject<BLayer.TestBO>();


I think using this kind of creational pattern makes the application not scalable as the same instance will be shared among all the concurrent users.Is it correct?

Is there any better way to abstract the creation and maintaining instance of business objects

Class code:namespace Microsoft.IT.RelationshipManagement.Internal.CISF.Infrastructure

using System.Linq;

N Tier - How Should Lookup Values Be Represented In Business Objects

Mar 25, 2011

I'm currently writing an N-Tier architected ASP.NET system with a relatively normalised SQL database backend, but I'm struggling to get my head around how lookup values should be represented in my business objects (I don't get the priviledge of using EF or ORMs). My table (as an example) could be structured like this:


ID | Name | Favourite_Colour
01 | Peter | 01
02 | John | 03
03 | Mary | 05


ID | Colour | is_active
01 | Red | 1
02 | Green | 1
03 | Blue | 1
04 | Pink | 1
05 | Black | 1

Now initially, I had created my business object to look like this:


I'm 100% convinced that I'm (a) overthinking this, and (b) making it more complicated than it needs to be. So, is there a preferred way of doing this? Or is there an option that I've overlooked?

DataSource Controls :: LINQ Mapping To Complex Business Objects?

Feb 5, 2010

I have two business objects mapped via LINQ to tables. One of the objects contains an instance of the other object and share a key as an identifier.I want to retrieve Class A and within class A all of Class B's values as well. What I am doing is this:



This seems a little clunky, as in slow. Is there a better way to get the Class B (User) information without making a query every time?

MVC - Mark Multiple Fields Invalid In Custom Validation Attribute?

Mar 2, 2011

I have a form where users enter their preferred contact method. It has:

- a radio button where a user selects whether they'd like to be contact by phone or email or either

- a textbox for the user's email address

- a textbox for the user's phone number

I have validation via a custom attribute that verifies that if the user selected phone they entered a phone number, if they selected email they entered an email, etc... but it's at a class level on my ViewModel. As such the validation doesn't mark the expected field as invalid.

Is there a way that my IsValid override (or some other method) can mark the child property's value as invalid so I get highlighting?

How To Bind Form Collection Back To Custom Model Object That Uses 2 Custom Objects

Mar 23, 2010

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:

public ActionResult Details(VideoDetailModel vidAndComment) { ....}

The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.

public class VideoDetailModel
public VideoDetailModel()
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.

For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

Alternative For Table Mark Up Not Working Properly

Feb 5, 2011

Using Visual WebDeveloper 2010 Express and ASP.NET 4.0 don't know whether its relevant but the whole thing is in a ContentPlaceHolder and inside an UpdatePanel. To avoid using the old table tr td model, I have created a simple form like this

<div class="admin-form">
<asp:Label ID="UserNameLabel" runat="server"
Text="User Name" />
<asp:TextBox ID="UserNameText" runat="server"
<br />
<asp:Label ID="PasswordLabel" runat="server"
Text="Password" />
<asp:TextBox ID="PasswordText" runat="server"
<br />
<asp:Label ID="ConfirmPasswordLabel" runat="server"
Text="Confirm Password" />
<asp:TextBox ID="ConfirmPasswordText" runat="server"
<br />
<asp:Label ID="EmailLabel" runat="server"
Text="Email" />
<asp:TextBox ID="EmailText" runat="server"
<br />
<br />
<br />
<span class="form-label"></span>
<asp:Button ID="CreateUserButton" runat="server"
CssClass="button blue"
Text="Create New User"/>

And the CSS

width: 300px !important;

This renders incorrectly as I would like to have all textboxes vertically lined after taking 300px. What is wrong? I cannot use HTML Controls like label as I have resx for globalization

Preparing A Database Driven Site Before Going Live?

May 18, 2010

I've got a really good idea for a service I'd like to create for the web, but since I'm new to ASP.NET I'd like to get everything up and running before I go and buy hosting etc.

What I'm curious about is the database side of things.

I don't quite understand how I can create a datebase on my computer for the sake of testing and practicing (Presumably through mssql server) and then just transfer it to a hosting account when I'm ready.

I guess the main part I don't understand is how can I connect to a database on my computer via my application and then change the connection so that it points to the web version when I'm ready.

I know that when you create the database and include it in your project it's not technically inside your project (Right?), but it just seems that the application is very rigid once you've specified the connection.
