C# - Class Structure With LINQ, Partial Classes, And Abstract Classes
May 17, 2010
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).

I'm building a web app that will keep a events in a database and add the event to a Google calendar on insertion.
I have three types of events, PendingEvents, ApprovedEvents, and DeniedEvents. I'm using single table inheritance through LINQ-to-SQL, with the Event class being abstract and the 3 types inheriting from it
Each type of Event is stored in calendars differently. I would like to use an abstract member function in Event called AddToCalendar.
I'm trying to set this up in a separate class file because I'm using the LINQ-to-SQL designer and I don't want these to be overwritten if I change the LINQ diagram.
However, I get an error from all three inherited classes that "'WebCal.ApprovedEvents' does not implement inherited abstract member 'Edu.Northwestern.WebCal.Event.AddEventToCalendar()' WebCalendarWebApplication1App_CodeWebCalDataSource.designer.cs"
It looks like it won't check my outside file and only looks at the designer.
The non-designer partial class file looks something like this:
public partial class WebCalDataSourceDataContext : System.Data.Linq.DataContext
{

Is there any way to list all the class in my ASP.Net application(Including class in App_Code and Partial Class(aspx pages and asmx user controls)

Do we have to do something special to have ASP.NET partial classes aware of controls that are declared in our user control's base classes? The partial classes keep generating declarations for controls in the base class which mean the controls in the base class get hidden and are null.

I am having a problem mapping a many-to-one relationship from an abstract base class mapping to a concrete union-subclass. Example:
public abstract class Entity
{
public virtual Guid ID {get; set;}
public virtual string Name {get;set;}
public virtual User OwnerUser {get; set;}
}
public class User : Entity
{
public virtual string UserName {get; set;}
}
I have a base abstract class for all of my database objects. I am mapping these classes with the Entity class as the abstract mapping class and the User as a union-subclass. When creating the configuration object, no errors are thrown and the Schema exports just fine. However, the field to the OwnerUser just won't show up in the database for all of the concrete classes. Here is an example of how the mapping looks
<class entity-name="Entity" name="Entity" abstract="true">
<id name="ID" type="guid">
<generator class="guid.comb"/>
</id>
<property name="Name" />
<many-to-one name="OwnerUser" column="ID" entity-name="User" />........
I am also using an Oracle XE instance as the database backend. If this isn't enough information to properly answer the question, let me know and I will add what I can.

I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?

I'm using Entity Framework to create my data objects. Here's what my designer.cs file looks like:
[code]....
But my validations aren't loaded. If I try to submit the form with no value for Name, I get an error message saying The value '' is invalid. instead of my error message.

I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.

I am trying to setup a base product class that will be inherited by a more specific class later. Here is my scenario. I have a table called ProductBase, it contains three fields, BaseProductId(PK), CatalogNum, and ListPrice. Every product in the system will share these attributes. Next, I have a table called Shirt, with three fields BaseProductId(PK, FK), Color, and Size.
I then setup an Entity Data Model that pulled in both of these tables, and created to classes BaseProduct and Shirt.
So, in my model, I want to do something like this:
[Code]....
The problem I have with this approach, is that I cannot force the properties for the Shirt. What if I make a change to the BaseProduct? What happens when I have multiple product types, will I have to repeat this code?

I've been tinkering for hours and I can't figure this out. Seems like it should be pretty straight-forward. Is it possible to use reflection to get a reference to a partial page class given the page's name and path so that I can iterate through the page and examine its controls? I am not looking to examine the currently loaded page, but another page within the same website.

The symbols won't load for a partial class (i.e. MyPage.aspx.cs code behind) and I need to debug that part of it. How do you get the symbols to load for a partial class and thus debug it while attached to process?Some other details: I publish my website (its an ASP.NET 2.0 site) which is with "Use Fixed naming and single page assemblies" checkbox which just creates a .dll for each aspx.cs code behind but no .pdb version of it. There are other ways to deploy like a single .dll file.

I have a virtual directory called "MySite.web", and a folder inside this directory called "Sell" where I have my webform Create.aspx and several user controls like CreateAd_CarsAndTrucks.ascx and CreateAd_Motorcycles.ascx.When I try to compile, I get several errors in Create.aspx stating that public partial class Sell_CreateAd_CarsAndTruck, Sell_CreateAd_Motorcycles are not recognized. I am looking at both classes right now (they're in the same folder), so I have no idea why the compiler's not finding them.One odd thing is that, for a moment, it did find one of them (Sell_CreateAd_CarsAndTruck), but from an assembly in either folder "Temporary ASP.Net" under c:Windows or the one in c:usersusername. So I closed my IDE, and deleted both folders. When I open the solution once again, it recreates "Temporary ASP.Net" under c:usersusername and then creates a "App_Web_createad_carsandtrucks.ascx.5a5f4927.ebg000r0.dll" that it uses as definition for the class. But it never uses the actual class as a definition. Basically, when I right-click on the class instance to view its definition, it takes me to metadata.

Why are Razor views not generated as partial classes? Making them partial classes gives us the option to have a code behind where we can do some of the stuff we're forced to do in the template itself in the code behind file.
Yes, I know the standard "go-to" thing is Html helper but I don't want to use Html helpers for these things as they are too specific to the view in question and besides, having a clutter of extension methods is just not the way to go.
I'd like to see Razor views generated as partial classes.

I have written a t4 template that basically replaces the work done by StronglyTypedResourceBuilder to give design time access to string resources as properties of classes, one class per resource file. Why? Well I needed to add some customer code that handles string token substitution and a few other customizations. Anyway, the template is working out really well and I may blog on it soon.
In the mean time though, following a common pattern, I have one .resx file for each view, master page, controller, etc. I would really like my t4 template to add a property to each such entity that gives quick access the custom resource class associated with it. For controllers this is easy. T4MVC is ensuring that they are a all declared partial. All I need to do is create the appropriate partial class in my output that declares a readonly property that returns an instance of the appropriate generated resource class.
The Problem:
I would like to do the same thing, inject generated code, into my views. Were this traditional ASP.Net, each .aspx page would have a .aspx.cs page and possibly an .aspx.designer.cs page that are all partial classes extending in the aspx page's class definition. There is no such thing by default in MVC and for good reason. However, I think for my purposes, if there is a way to do this, it would be the way to go.
I could subclass ViewPage and add a generic type parameter and a property that returns the class of that type but that has certain complications. I think adding auto generated code to each view via partial class (that is what partials are for after all) is the way to go.
I have made a basic attempt. I have created a .aspx.cs file for a view and placed a code behind attribute in the page declaration but the class generated from the view seems to reside in a different assembly any my "partial class" ends up as its own class in the same assembly as all my other code.

I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?

For no apparent reason (of course there must be one), my web project will no longer generate LINQ to SQL classes/data contexts!!!I am going about the usual routine of right clicking the project, adding new item, selected LINQ to SQL classes, then dragging over a table from Server Explorer, saving and build but no...the bloody thing won't appear!!!Does anyone know why this might be happening/what have I done wrong?

suppose i have Class A with some properties and Attributes, and Class B with the same, how can i merge these 2 class Properties and properties Attributes into 1 class at runtime, or better is how can i add these 2 classes into a a third class as properties of this new class with their Fields, Properties, Methods, etc... at Runtime ?
using reflection or the News .NET 4.0 Dynamic or expando Object
what i want is to create a dynamic ViewModel for MVC, where other classes are in some other assemblies, and i want them to be part of the model with their Datavalidation attributes. and i don't know how many or what exactly these classes are goanna be, so i want to iterate through assemblies and choose them then add them to the main View Model

I have following two classes:
public class A : System.Web.UI.WebControls.Button
{
public virtual string X[code]....
As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.

Technically I have the Data Annoations working with Linq to SQL classes - the problem is when validation
passes. When UpdateModel() tries to do its thing i can an error:The model of type 'MyProject.Models.Employee' could not be updated.What i did was i created a partial class for Employee (that is generated by linq to sql), then stuck a Meta Data class on top of it for the validation
[Code]....
And in my master page i include
<script type="text/javascript" src="/Scripts/jquery.validate.min.js"></script>

I am updating a project I wrote some time ago. At the time my preference was for DataSets and DataSetTableAdapters, but I've now moved on to use Linq to SQL DataClasses. I would like to convert the project to Linq to SQL, but I am tight on time and it's a big job. My question is, is there any reasons I can't develop new modules using Linq to SQL DataClasses along side DataSets and convert the DataSets overtime?
Apart from the obvious confusion it will cause, are there any technical problems I should be aware of i.e. will there be any performance problems using the two methods?

I am used to making separate Business Object and List<> classes for my DB tables. Sometimes I just have a basic task in hand as displaying a list of year for a search box or having some values in a drop down.
Right now I am ending up with a lot of separate classes and List classes<> for these basic operations.
How can I make a single class for some basic tasks as these by using generics? I want to have single class for some methods like get current year, employee names, Department Name/Code, Title etc. I am using .NET 2.0.
Edit
After some searching, I found that I can achieve similar tasks by creating a DTO namespace.
What I don't get right now is how to create multiple classes inside my DTO class. Say 1 class for just returning 'year', One for 'Employee Name/Code' and so on inside the single DTO class.
