MVC :: TagBuilder Missing In MVC 3 RC - How To Get Class
Nov 10, 2010
I am updating some code from MVC 3 Beta to MVC 3 RC.
TagBuilder is unrecognized. Did the way helpers are created changed?
If not where is the TagBuilder class?
And where can I find MVC 3 Source Code?

I know this is kind of obsessive, but is there a way to control the order that the TagBuilder class renders the attributes of an HTML tag when you call ToString()?
i.e. so that
var tb = new TagBuilder("meta");
tb.Attributes.Add("http-equiv", "Content-Type");
tb.Attributes.Add("content", "text/html; charset=utf-8");
tb.ToString(TagRenderMode.SelfClosing)
will return
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
not
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
Changing the order that you add the attributes doesn't change it, it seems to be rendering in alphabetical order

I'm having a little problem with the popout icon in the ASP menu control not appearing when the sitemap node doesn't have a URL. Take the following sitemap nodes as an example:
<siteMapNode title="Top 1" url="~/Top1.aspx">
<siteMapNode title="Sub 1" url="~/Sub1.aspx" />
</siteMapNode>
<siteMapNode title="Top 2">
<siteMapNode title="Sub 2" url="~/Sub2.aspx" />
</siteMapNode>
The first top level item - Top 1 - gets a popout CSS class written to the tag that spans the label. However the second top level item - Top 2 - does not get the class. Given this class is generally used to hold the arrow indicating there's more content beneath the item there's a bit of a usability problem here. Does anyone have a workaround for this? Or alternatively, is a sitemap node without a URL attribute somehow breaking the intended usage of the control?

I am looking to write a few helpers in my own assembly modeled after the helpers in System.web.mvc. My problem is that I cannot use the call to Tagbuilder.ToMvcHtlString since it is internal. So if I return a string it wont be ready for asp.net 4 when it comes.
I don't want to add anything to system.web.mvc as that is a given dll.

was tagbuilder dropped in favour of Razor syntax?
If not, where did it go? It used to live in System.Web.Mvc -- not anymore.

When upgrading to mvc2 i noticed some of my javascript that was keying on "Points[0]_Id" (this is invalid for an html id btw) started to fail. I pulled up the source and noticed that the TagBuilder class now generates valid client id's and replaces all invalid characters with the "IdAttributeDotReplacement" (which is a terrible name now, since it's not just a dot replacement character anymore). I started to look for a way to generate client id's using a helper built into mvc and came across HtmlHelper.GenerateIdFromName, but this still generates ids the invalid way!
TagBuilder.GenerateId( "Points[0].Id" ) = "Points_0__Id"
HtmlHelper.GenerateFromName( "Points[0].Id" ) = "Points[0]_Id"
IMO: the tagbuilder class or the GenerateFromName code should not be duplicated in two different spots or else you will get errors like this. Also I consider this change made to TagBuilder.GenerateId to be a breaking change and should be included in the breaking changes section of the release notes.

Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

I first need to apologize in case this has been answered before but I'm a newbie (green as they come) and this error keeps popping up even before I start debugging! There are two errors and the second one is:" Error 2
Missing partial modifier on declaration of type 'WFPKenya2.WFPKenya2'; another partial declaration of this type exists"

I have this Control directive in a usercontrol (i've changed the namespace and class name):
<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %>
<asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" />
ClassName is a class that lives in a class library and this is the class:
namespace Namespace.Path.To
{
public class ClassName : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.TextBox txtComment;
protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Response.Write(txtComment == null);
HttpContext.Current.Response.End();
}

I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.

In my MVC project, 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 classes BaseProduct and Shirt. So, in my model, I want to do something like this:
[Code]....
The main problem I have with this, is that if I do any kind of condition on CatalogNum or ListPrice, then my performance goes to crap. One of the main things we will want to do is something like this:
[Code]....
This takes an enormous performance hit, and I suspect it is because the partial class above returns to the database for each shirt.
The other 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 assume I will need to make a change with the entity data model, but I am unsure where to begin.

I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?

I am going to have multiple "types" of an object and I am really not sure how best to retrieve/save those multiple types without having a separate save/retrieve for each type.
My classes:
[Code]....
I hope this makes sense. I'd rather not add a "type" column as I have this in another part of my database and I am not really liking it too much
UPDATE
Here's more info/questions for clarification, if necessary.
I'm really at a loss for how to incorporate them into my repository pattern.
When I call getEvaluation, I want it to return an abstract Evaluation, but I'm struggling with this code. Same with Saving - any insight on this would be excellent
UPDATE 2
Database:
Evaluations
Id (PK)
Comment
EvaluationType1
Id (FK to Evaluations.Id)
Field
EvaluationType1
Id (FK to Evaluations.Id)
Field
So, in getEvaluation(int id), I need to figure out what type of Evaluation they want. Does this mean I should pass in a type? Same is true in saveEvaluation, But I can do a switch/function map to see what Type it is.

I have a class instance which is created by using Activator.CreateInstance() method. That class instance contains helper methods which are frequently used throughout the application. In order to avoid creating the instance multiple times, I'm just thinking about implementing an appropriate caching mechanism. The following consideration should be taken into account:
1) I can't use static class and methods.
2) There are around 6 instances (1 instance per class) per App Domain.

Here When i create object of Class InheritingOneConstruntor value of public field var1 is zero at last. But when i checked step by step through debugging i found that when base class's New() constructor is called, for a moment all var1's value becomes 89. All var1 means at all locations where var1 is used i.e., in base class and in child class.But the moment control exits New() constructor of base class, var1's value again becomes zero. Why it happend ?
