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?
Even though I when I create a linqtosql class I mark C# as the language it was always shows up as a Visual Basic file in the App Code file. I can't get it to stop doing that. ????? What is going on?

View 3 RepliesI'm using VS 2010. I got the references to the classes from my project, now I need the .dll files but I can't seem to find them. How do you add the .dll's?
View 1 RepliesI 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?
I've searched but not found much that helps, could be using wrong search terms.Anyway, currently using Visual Studio 2005 and VB, but just got Visual Studio 2010 and trying to use C# and am having problems using classes, I think I'm missing something simple here.
In both 2005 & 2010 I create a new website and a Default.aspx, in 2005 using VB, C# in 2010.
Right-click the project -> Add New Item -> Class, and leave it as Class1.vb/Class1.cs
Both 2005 & 2010 prompt to place it in the App_Code folder, so choose yes.
Here are the class files, I've not changed anything apart from create a very simple function:
Class1.vb code: [Code]....
Class1.cs code: [Code]....
In my VB project Default.aspx.vb: [Code]....
No errors, and debugging shows that a = "hello"
My Default.aspx.cs: [Code]....
This gives an error:Error 1 The name 'tester' does not exist in the current context D:Visual Studio 2010WebSite11Default.aspx.cs
How do I reference the tester function within Class1 in my C# project?

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.
I've build a Class Library, in the same project i put a web project. But its impossible to access the classes from the dll generated by the class library. Whats wrong? JumpTide XML uses the namespace like:
namespace JumpTideClassLib
{
public class jumptidexml
{
public class MetaTags
{
Image:
My class names are this annoyingly bright-blue color and I can't figure out which display item class names would fall into under the fonts and colors option.

View 1 RepliesI am fairly new to ASP.net and web page development. I normally create Windows Apps, but the move is on to web pages. I have read and tried a number of posts on this matter, but none of them resolved the problem I am having. I have created a web site (I'm positive it is a web site) and added a class. Visual Studio automatically created and added the class to the App_Code folder. Accordingly, I added the get/set methods to the class and made them public. When ever I try to access the class from a code behind for any page, I get the class name, but nothing more. Intellisense shows only Equals and EqualsReference - no variables. I'm used to using classes in windows forms application and this would make life so much easier if it worked like it is supposed to work.
View 2 Repliesmy solution in VS 2008, consisting of a dozen projects, does not compile because it gives me errors on constructors of a couple of classes, telling me that lacks the constructor that takes one parameter, which lacks the parameterless constructor, and so on.Actually I have all the correct constructors, and other times I compile without problems.I'm not understand why I have these random problems, that it is practically impossible to replicate.

i can't fetch the Store Class Methods or Function because its out of project directory, as its showin in image.
I can't believe I'm having so much trouble finding this information. I'm endeavouring to learn about creating model classes with Linq to SQL. By default VS2010 wants to use SQL Express, but our organisation has several database servers for development so I'd rather use one of those. PLEASE can somebody tell me how I can configure VS2010 to do that, as all I get is 'A network-related or instance-specific error occurred while establishing a connection to SQL Server ... Verify that the instance name is correct'. Yeah, thanks Microsoft. Actually telling me how to verify the instance name would be a really good move here.
View 1 RepliesI came across the article few days ago where somebody said that it's possible to automatically break down ClassName.Designer.CS into multiple classes.
So instead of having Customer and Order class definitions in one .CS file I'm going to have 2 .CS files: Customer.Designer.CS and Order.Designer.CS
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 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 have an MVC project setup, and I've brought the subsonic Active Record templates into my project, and they generated successfully and I can use the subsonic classes to access my database. However, how do I create a strongly typed view using the subsonic generated classes? When I select "add View" and I check the checkbox to create a strongly-typed view, none of the generated classes from subsonic for my data are available.

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

View 3 RepliesWhen I use TT files to generate code, output files within Websites ar never properly generated. The resut is always some "Chinese character garbage", and the generated extension is always .cs (whatever the given outputextension may be)Generating text files works fine in class libraries, MVC websites and other "projects".Just not in plain websites. Is this a known issue, am I forgetting some swith or doing something wrong, can or can I not fix this?UPDATE: It seems to be a problem with the Tangible T4 Editor, after uninstalling this tool, it seems to work fine. However, I've lost syntax highlighting and intellisense then.Since this is an external tool, I don't think this forum covers that scope.
View 4 RepliesI 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.
So I used this tutorial to generate my poco classes which I am to use throughout my aplication.. the problem is that Im not supposed to modify the generated cs files cause they get autoregenerated... How do I add attributes like [Required] and stuff like that??
View 2 RepliesI'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?
