View 3 RepliesI can access a module from code behind but not from the aspx page in inline VB code <% ... %>.
I know its got to be something simple but I can't seem to find the answer anywhere.
I am to access a method on my master page. I have an error label which I want to update based on error messages I get from my site.
public string ErrorText
{
get { return this.infoLabel.Text; }
set { this.infoLabel.Text = value; }
}
How can I access this from my user control or classes that I set up?
I created a webpage names Default.aspx. In its code behind i defined another public class named Test. Test class is not accessible in other pages code behind although it is defined as public.
View 8 RepliesI have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.

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 ?
How do declare a public variable .aspx web page that can be used in all the pages within my web application? And/or create a Public Sub?
View 3 Replies 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

Is there any way to list all the class in my ASP.Net application(Including class in App_Code and Partial Class(aspx pages and asmx user controls)
View 3 RepliesI'd like to be able to determine what class will be called given an URL. For instance, I have a page /First.aspx that has a hyperlink to /Second.aspx In the code behind for First.aspx.cs, I'd like to be able to determine what class will execute if someone clicks on the hyperlink that points to /Second.aspx.
EDIT: One of the reponders asked me to outline the problem I'm trying to address. Here it is: The codebase I inherited has a subclass the System.Web.UI.Page that has a public Authorized method that returns a boolean. The Authorized method checks the parameters passed via the query string against the authenticated user, and determines whether that user should be allowed to call that page with the given parameters.
Elsewhere in the site I have hyperlinks that reference those protected pages. In some instances those links are displayed to users who are not authorized to navigate to that page. They can click the link, however they get an error. In other instances, prior developers when through the trouble of inserting logic that hides the hyperlink for those unauthorized users, but the authorization logic is duplicated (In the page itself, and in the linking page). What I would like to do is create a subclass of the hyperlink class, and have the subclass inspect the NavigateUrl, determine the destination page class, and call the Authorized method of that class to determine if the user is authorized to call that page. If the user is not authorize, the link will automatically hide itself.

I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have.
public partial class TestPage : System.Web.UI.Page
{
protected DirectoryInfo dir;
protected FileInfo[] files;
protected void Page_Load(object sender, EventArgs e)
{
dir = new DirectoryInfo(Server.MapPath(@"\sharedDrivePublic"));
files = dir.GetFiles();
}
}
The aspx page looks kind of like this:
<% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %>
<ul>
<% foreach (System.IO.FileInfo f in files)
{
Response.Write("<li>" + f.FullName + "</li>");
} %>
</ul>
When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.

I have a property on my Global.asax.cs class that I need to access from a business class, i.e. using HttpContext.Current. How do I do this? Global.asax.cs (in a web project)
public partial class Global : System.Web.HttpApplication
{
public static ProxyGenerator Generator = new ProxyGenerator();
Business class (in a separate business project)
var generator = ((Sei.Osp.Web.Global)HttpContext.Current.ApplicationInstance)
This obviously doesn't work and I don't want to reference the whole web project in the business project as it will create a circular reference (the business project is already referenced in the web project)
UPDATE:
To clarify - the property I'm creating holds an instance of the Castle Dynamic Proxy Generator class. I've read that you shouldn't just create this all over the place. So I thought I'd create it in my Global.asax.cs and then just use that instance wherever I need to create a proxy class (I'm using it to do AOP) Is there a better way of doing this?
My project is developed in asp.net 2.0 and uses the System.Web.Extensions.dll in it. The project was working fine earlier.

But, didn't solved the issue.

I am using Visual Studio 2008 with .Net 2.0
I am maintaining and old application in ASP.Net and it has one CustomGridView control with 4000 lines of code. I see that in that file only, when I try to modify any code the IDE does not respond quickly as it does for other files. I thought of creating partial classes for the same but it seems that VS is not reconginzing the new partial class. I am trying to use the variables from the old partial class and it is not able to reconize any variable or method.

View 6 RepliesI have 2 projects. A data project, which contains my database and my Entity Framework model. I have table called 'User', and then have a generated EF class for user. I am trying to add a partial class:
using System;
using System.Collections.Generic;
using System.Data.Linq;
using System.Linq;
using System.Text;
namespace Data
{
public partial class user
{
public bool isValid
{
get {
return (GetRuleViolations().Count()==0);
}
}
public IEnumerable<RuleViolation> GetRuleViolations()
{
yield break;
}
partialvoid OnValidate(ChangeAction action)
{
if (isValid)
throw new ApplicationException("Rule violation prevents saving");
}
}
public class RuleViolation
{
public string ErrorMessage { get; private set; }
public string PropertyName { get; private set; }
public RuleViolation (string errorMessage)
{
ErrorMessage = errorMessage;
}
public RuleViolation(string errorMessage, string propertyName)
{
ErrorMessage = errorMessage;
PropertyName = propertyName;
}
}
}
This is following the MVC 1.0 NerdDinner example. However, I am getting a design time error on the OnValidate method:
partial void OnValidate(ChangeAction action)
{
if (isValid)
throw new ApplicationException("Rule violation prevents saving");
}
No definining declaration found for implimenting declaration of partial method 'void OnValidate(ChangeAction action)' What am I doing wrong?
