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.

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'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.

I am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.

I was wondering if you should write code so that external classes and functions of that external class can access the webform controls in the main class???
Or should you only use the external class to process some data, return that data back to the main class (that instantiated that external class object) and then have an internal function in the main class to deliver the data to the control? (back to the screen)

I'm using Entity Framework to create my data objects. Here's what my designer.cs file looks like:

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 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?

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.

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.

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 have a user control in which I have declared a connection string as a private class variable.
I have a bunch of cascading dropdown lists in this control.
In one of my subroutines PopulateDdlPostalCodes I get an error "Connection was not initialized".
In all the other subs that use Conn, the class variable is being recognized.
If I duplicate the declaration of Conn in this sub then all works ok.
Why is this sub different than all the others?

I have created an imageurl and label ids inside an itemtemplate which is inside a datalist but when I want to do some programming based off of those two ids, the code behind files do not recognize anything inside an item template.
Is there a way I can retrieve from an itemtemplate onto say like a string in a code behind file?
To make my explanation easier this is what I'm trying to do:
I have two div tags, one on the left and one on the right.
The div tag on the left contains a datalist of an Itemtemplate of various pictures.
When you click on one of these pictures, the same picture you clicked on will display in the right div but larger width and height.

I thought I finally had this cracked but now I want iterate through the records in my listview and do different things depending on whether the record is displaying existing data or is a blank, new record. Easy, right? Here's my code:
[Code]....
The problem is that the listview doesn't seem to recognize the insertitem as such. Obviously I don't really want that message box in there but it was just to test whether the insertitem was being picked up. The message box is never displayed.I also tried a simple iteration through the listview items with a message box popping up on each item displaying the item type. It said 'DataItem' every time, never 'InsertItem', even though there is definitely and insert item there!!

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 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 using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...

I'm using VB.NET and Razor (ASP.NET MVC 3.0). I have a VB.NET module defined in which I declared a number of public constants. However, those constants are not being recongized in views. The constants are being recogized in my model classes.
I do import the namespace in the view (that is, the first line I have in the view is "@Imports MyNamespace"). Yet, when I try to use the constant in a statement like:

the constant MYFORMAT_DATE_LONG is not being recognized. And I did try putting an @ in from of the constant name too:

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?
