ADO.NET :: Partial Declarations Of 'Shirt' Must Not Specify Different Base Classes?

Dec 15, 2010

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?

How To Make User Control Partial Classes Aware Of Controls Declared In The Base Class

Mar 5, 2010

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.

C# - Can Base Classes See The Protected Fields Of Derived Classes

Aug 11, 2010

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.

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).

Architecture :: Two Different Base Classes Sharing Some Of The Same Code?

Mar 21, 2011

I got loads of website, that share one of two baseclasses. I need the two baseclasses to be able to share part of the same code. I dont want to have to duplicate the shared code per baseclass.

so.. I got a page.aspx that inherits the baseclass and that inhertis 'sub' baseclass that inherits the web.ui.page class. So far so good :-)

In my baseclass I got a Public (at the top of the class not in any method- not sure of the proper term) Varable that is constructed from a structure in the BO class.

it Public PageDetails AS CoreDomainSetupBO.GetStartUpDetails = {database method}

I need the pagedetails to be available in the sub baseclass but it cant be defined there as the page details value is defined differently in the different base classes.

I hope that makes sense, I need to sub base class to be able to use a property that is defined at baseclass level.

Web Forms :: VB.NET - Import Statements And Base Classes?

Aug 19, 2010

I have a BasePage class that all of my content pages inherit from. In my BasePage, I have many Import Statements. It seems as though they carry over into the derived class as one would expect. However, if you were to try and access code in the client aspx design page, as you would in the code-behind, you run into problems.

For instance, in my BasePage i have a Public Enum named ThemedSites. It's just an enumerator that lists the 5 different themes my site could be skinned as. I, at times, need to do different things in code, and in design, depending on what theme I'm currently in. I have a Public Property named CurrentSite (might have been more appropriate to say CurrentTheme, but that's besides the point). CurrentSite's return type is ThemedSites. So in code, one would say something like:

[Code]....

This works great in any page that inherits the BasePage class. This falters when that very same logic is used in the design page like:

[Code]....

Now, it works if you fully qualify both sides of the condition, but that's not my question. My question is: why isn't the Imported NameSpace in the BasePage recognized in the client-side server tag, as one would think it would be, according to how it IS recognized in the server-side code-behind?

C# - Mapping NHibernate Many-to-one Relationships From Abstract Base Classes To Union-subclasses?

Nov 19, 2010

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.

Web Forms :: Reflection And Partial Page Classes?

Feb 8, 2010

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.

.NET Partial Classes And Attach To Process Method?

Jan 10, 2011

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.

Web Forms :: Webform Is Not Recognizing Partial Classes?

Nov 16, 2010

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.

MVC :: MVC3 Beta Razor Views - Not Partial Classes?

Oct 12, 2010

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.

MVC :: How To Inject Auto-generated Code Into Views Via Partial Classes

Sep 16, 2010

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.

Does anyone have any links to documentation on how the new architecture is creating these control declarations?

Call Always Base Class Method Like Base.OnInit()?

I am new in asp .net.I am not able to undestand why we call base class method when we
override methods/events.Like automatically visual studio will put base.OnInit() if you are overriding OnInit.

protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}

same is the case of Finalize. In derived we call base.Finalize() Is there any need of calling these base class methods ?
