Web Forms :: Having BasePage Class Outside The Current Project/Could Not Load Type
Jun 10, 2010
We are using nested master page the master page is seperate class library project and all the other projects refer to them. We wanted to have a basepage class which load title, meta tags and keywords dynamically. It was working fine till it was inside the main project. We wanted the basepage class to be more generic and to have it reside in a single place. So i tried created a seperate class library project but i getting error "Could not load type" ..
How to have the basepage class outside the project?

I have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@
Page
Language="C#"
MasterPageFile="~/Master/Layout/MasterPage.master"
AutoEventWireup="true"
CodeBehind="xxxx.aspx.cs"
CodeFile="xxxx.aspx.cs"
Inherits="xxxx"
ValidateRequest="false"
EnableEventValidation="false"
ViewStateEncryptionMode="Never"
CodeFileBaseClass="~/Master/App_Code/BasePage<Page>"
Title="Title"
Meta_Keywords="xxxx,yyyy,zzzz"
Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.

We are trying to use a BasePage class (which inherits from Page) to populate and set the Meta Keywords and Meta Description Tags. I am using masterpages and below is an example code extract... According to examples on the internet, I could then set this also via the Page Directive using the MetaKeywords and MetaDescription properties, but they do not appear.
I have tried setting the CodeFileBaseClass="MyNamespace.UI.BasePage" but this does not work either. Using debug I can see that the BasePage classes' MetaKeywords and MetaDescription properties are not being set within my content page. I can access the properties but not set them.

== PAGE CLASS ==

I have had a project called Articles and the project complies fine. I have it running as a seperate site on my machine and it works like a charm under IIS7. When I start the project from VS2010 in debug mode (by pressing F5) it lands on a page that says: "Parser Error Message: Could not load type 'Articles._Default'."
I i however change the path in the browser from [URL] Home it works fine again, indicating that my routing table is bust but it was working yesterday and I did not change any route, The error page also says: "Please do not delete this file. It is used to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request to the server." That idicates to me that it went to default.aspx...right?

Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?

I have an ASP.NET 3.5 website application using C# and SQL 2005 running on a web server. Now the application has the ability to create new aspx pages with content and the relative aspx.cs and design.cs pages needed on the fly and store them in the base directory on the server. Think of it as a crued Visual Studio website on the server for admin to click a few options on a page then the new pages are created for them without the need of a web developer. This all works fine and the code is working 100% (for the moment).
My problem now is the following: When i now navigate to this newly created page i get the following error - Parse Error : Could not load type 'Namespace.PageName'
I've looked into the reasoning and microsoft say "These errors occur if the .aspx page contains a reference to a code-behind module and if the application has not been built." Which now makes sense the application does not realise that these new pages are part of its system even though i can navigate to them.How do i get the system to recognise these new pages and rebuild itself accordingly?Now i cannot rebuild the system localy then reupload to the server, this needs to be accomplished on the server by the system, because the site cannot afford to have down time everytime admin decide to add new pages.

What cool functionality and methods do you add to your ASP.net BasePage : System.Web.UI.Page classes? Here's something I use for authentication, and I'd like to hear your opinions on this:
protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
// Authentication code omitted... Essentially same as below.
if (_RequiresAuthentication && !(IsAuthorized))
{
RespondForbidden("You do not have permissions to view this page.", UnauthorizedRedirect);
return;
}
}
// This function is overridden in each page subclass and fitted to each page's
// own authorization requirements.
// This also allows cascading authorization checks,
// e.g: User has permission to view page? No - base.IsAuthorized - Is user an admin?
protected virtual bool IsAuthorized
{
get { return true; }
}
My BasePage class contains an instance of this class:
public class StatusCodeResponse {
public StatusCodeResponse(HttpContext context) {
this._context = context;
}
/// <summary>
/// Responds with a specified status code, and if specified - transfers to a page.
/// </summary>
private void RespondStatusCode(HttpContext context, System.Net.HttpStatusCode status, string message, string transfer)
{
if (string.IsNullOrEmpty(transfer))
{
throw new HttpException((int)status, message);
}
context.Response.StatusCode = (int)status;
context.Response.StatusDescription = message;
context.Server.Transfer(transfer);
}
public void RespondForbidden(string message, string transfer)
{
RespondStatusCode(this._context, System.Net.HttpStatusCode.Forbidden, message, transfer);
}
// And a few more like these...
}
As a side note, this could be accomplished using extension methods for the HttpResponse object. And another method I find quite handy for parsing querystring int arguments:
public bool ParseId(string field, out int result)
{
return (int.TryParse(Request.QueryString[field], out result) && result > 0);
}

I've created a new vs.net project and added all the files from an asp.net website project.
When I compile, it couldn't find a reference to a class.
In the AppCode the class was defined, but without a namespace.
So I added a namespace, and then on the default.aspx.cs (this is where the error was originating) I added the using statement.
The using statement was not picking up the namespace.

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 an ASP.NET web site project where I am using both VB.Net and C# class files. I have included separate sub folders in the App_Code directory for classes of each language.However, while I can successfully make use of a C# class in a VB class, I cannot do the opposite: use a a VB class in a C# class.
So, to illustrate, I might have two classes such as this:
Public Class VBTestClass
Public Sub New()
End Sub [code]....
I get an error that "the type or namespace "VBTestClass" could not be found". What am I missing here?

I'm working on an existing web project. All of the classes are in a seperate folder as vb files. I need to modify one to include a delete method. I think I can insert the delete method, my question is how do I update the project to include the modified class. I think that all of the classes are compiled into the project as a .dll which I don't know how to modify. I assume I need to modify the source vb file for the class and recompile?

I need to get a list of all of these webforms.
As the subject reads, how can i accomplish this ? All my webforms inherits from a class called "BasePage". It can also suffice with only getting a list of all the webforms in the application, regardless of base class since i can check inheritance later in code.
Reason i'm asking is because i'm building my menu and i'm implementing security enforced user visibility based on what pages there are in the webbapplication, and what roles each page demands, and display these to the user in the menu.
Using sitemaps are insufficient, i need to provide much more info for all the pages i have on my system.
Using this technique i can query my "PageProvider" for like:
GetAllPagesVisibibleToUser(MembershipUser user)
DoesUserHaveAccessToPage(MembershipUser user, BasePage forPage)
I'm also planning on implementing this technique on WebUserControls.

I have a standalone .ascx page, it has a grid and a datasource. This .ascx page is apart of the .aspx page that inherits from the base page. How can I reference the methods, properties from the base page from within my .ascx page?

I am very new to ASP .net. I need to create web application with ASP .net using VB. I have created a project and create web forms with Visual Studio 2005 (ASP .net version 2.0). And it was working fine on local host. However, I got an error after I published the forms on our hosting site. The error code was as following:
Line 1: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Login.aspx.vb" Inherits="KocaWebSite.Login" %>
Line 2:

I hate VS and this symbolic gibberish that never seem to have same solution (if it once was logic) twice. The screendump below says what it says.
As soon as I F5/Start the web project, the breakpoint going yellow. This ONLY affect the aspx.cs file that being changed. The other aspx.cs files can have breakpoints.
When I do rebuild/build all DLL and PDB files are created just fine. They have same compile time and are in same directory. Module-Windows i VS says the symbols are loaded perfectly. Well, yeah, try bite me!
I can tell, all symbolic is working just fine, until I was about doing changes inside those aspx.cs files (which was some time ago since last time). If I reset back the file, the breakpoint are working. If I try to make changes in another file, the problem appears there.
It simply appears like that the symbolic file generator don't understand changes maded in aspx.cs files..
