Visual Studio :: What Is The Difference Between Designer Classes And T4 Template Generated Classes

Jan 11, 2010

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?

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).

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.

Map Model Classes To ViewModel Classes Or Aggregate Model Classes In ViewModel Classes

Dec 15, 2010

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?

VS 2008 Linking Classes From Other Project?

Feb 11, 2010

The problem is that the classes calls forms, controls and other things that when in Web project makes error.

Visual Studio 2010 Puts 4.0 Classes Into 3.5 Project?

Jun 21, 2010

I have existing ASP.NET 3.5 project I migrated to Visual Studio 2010. I didn't migrate it to .NET 4.0. Every time I try to edit .aspx page, it alters the .designer.cs class to point to System.Web.UI.WebControls.WebParts.UpdatePanel class instead of

System.Web.UI.UpdatePanel

class and then the build of course produces an error. The project properties says ".NET3.5".Also the "design" tab produces just one box saying "unknown server tag asp:UpdatePanel". It seems like it is looking at .NET4.0 to generate the desgn view, not 3.5

Is there a setting somewhere I need to change?

Visual Studio :: Add Shared Classes / Files Into Project

Feb 20, 2011

VWD 2010 Express.

We have shared CSharp classes put into a shared folders for re-use. Now I want to add those classes into my project by creating a new folder:

1) Right click the solution,
Add -> New Folder
Give it a new, eg. SharedClasses

2) Right click the new folder "SharedClasses"
Add- > Existing Item...

Browse to the "Shared Folder", include those shared classes. But those files are added physically into the folder "SharedClasses" rather than a reference. How do I just add a link to those shared files? Since these files might be modified from time to time, I don't want to delete and add those file frequently.

DataSource Controls :: Created LINQ To SQL Classes And Built The Project, Then Created An Aspx Page?

I have been using LINQ to SQL for quite a while (about two years). Every thing was fine until now. As usual, I created LINQ to SQL classes and built the project, then created an aspx page. However, I cannot see the DataClassesDataContext in the code behind file. It is not listed in the intellisense list.

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?

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.

Web Forms :: Shared Functions And Classes Error

Oct 4, 2010

I have some code in my new asp.net app that I need to share. So i created a shared class called
"utilities.vb" and put it in the APP_CODE folder. There is a function I have in there that pulls a person's image based off of their MemberId.

[Code]....

And I can call this function from my page using utilities.FcnGetMemberImage(). Ok, so all good so far until it complains about...

"Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class"

when referring to the Server.MapPath()

But the problem is that if I don't make it a Shared Function, I can't access it from my other pages. But if I do make it a Shared Function, it throws this error. The fix is supposed to be that I either don't share the function, or

"add the shared keyword to the member declaration", according to Microsoft at
http://msdn.microsoft.com/en-us/library/xfsswe45.aspx

But I'm not exactly sure how to "add the shared keyword to the member declaration" or what this means exactly and how this might affect other parts of my code?

Or is there a better way to work around this dilemma?
