Web Forms :: Website Code Not Linking To Partial Class?
Mar 19, 2010
I have a website that i converted from asp .net 1.1 to 2.0 and now i have one page that said ambiguous reference because in 1.1.all controls needed to be defined in the class as well. Well after deleting those and leaving only the declares in the Markup,it says that the variables do not exists in current context. Intellisense allows me to use and reference them from the page but when trying to build it leaves me with that error.

I have a sitemap file included in a asp.net masterpage that I want to use CSS to format. Unfortunately, I'm having some problems getting the web.sitemap file to read the CSS file. The following is my code for the Web.sitemap file. Could someone give me the code for getting my document to read the CSS file. The following is a copy the code I have now.
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >

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 am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.

Last night you guys here on this forum helped me in accessing properties of a dynamically loaded UC in an aspx page. Now i am facing another hiccup.
My code behind is : public partial class SiteUserControls_Message_Messages : BaseControl
In one of the click events i am loading three web users controls:
protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)
{
SiteUserControls_Message_Create CreateNewMessageUC = Page.LoadControl(CreateMsgControl) as
SiteUserControls_Message_Create; // typecasting the UC
[Code]....
Now i want to access this variable CreateNewMessageUC in another event like this:
protected void MarkAsUnreadLinkButton_OnClick(object sender, EventArgs e)
{
CreateNewMessage.CreateNewMessageUC.RefreshSendTo();
[Code]....
But when i access teh variable in another event it is always null.

I'm an ASP.NET newbie, but not so new at programming in general.
I'm creating a commercial website, and I want to allow an admin to add new articles (an article consists of text, images and various properties such as category).
I am trying to decide the optimal Modus Operandi. This site is commercial, so SEO is a major consideration. This means that I want each url to be "unique". That is, if someone navigates to an article about raccoons, he should be redirected to [URL]. This means - I can't have one page that loads the appropriate article dynamically a-la AJAX (gotta use deep-linking)
So how exactly do I do this? suppose the admin entered his text, uploaded the images and set the article properties. I create a new subfolder, save the images to the server (I understand that saving images to a DB is a big no-no), their addresses in a DB, and the content itself to the DB. But now what?
How do I go about creating the actual page?
Is there a function for creating a new aspx file? then what about its corresponding cs file? Or is it unwise to use aspx? Maybe plain html? but then how does it work with my site's master page? Or maybe just create another copy of a general aspx file which is populated with an article according to a parameter?

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.

I 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?

I have a table of people with columns holding bits of info about them. I also need a variety of computed columns such as FileAs (lastname + ", " + firstname) and CityStateZip (you get the idea). I am wondering where best to put these definitions. It's worthwhile to note that the user will want to search for things as seen on the page, not the little atoms in the table. For example, searching on ", e" finds everyone whose first name begins with E. Typing ", az" to get everyone who lives in Arizona.
I noticed that linq-to-sql queries only recognize the fields in the table definitions, not any that are added in the partial class associated with the dbml. Linq-to-sql does work against computed columns in the database; however, the column definitions--especially for international address formats--will become very complex and much better handled in code.

I've looked around and I can't seem to find a good answer on this. Is there any cleanup needed on a strongly typed dataSet? I'm using DataSets as my DAL but I don't really have a BLL. I'm handling this in my code behind like this:
[Code]....
I'm assuming it handles the opening and closing of the connetion? The adapter has a dispose method. Should I be using this? Is there any cleanup necessary or does the partial class (that inherits system.data.dataset) handle all of this?

i am using linqtosql dbml to create table classes automatically.
however each time i update my database or dbml diagram, it refreshs designer.cs file and all code i wrote is gone.
so, i decided to make partial class to keep certain information alive.
but here is my question :
for example, User class is defined as follow in designer.cs file :
[Code]....
public string UserID{get;set;}
}
but if i do this, i get error message because UserID is already defined in designer.cs file.
should i delete all UserID variable in designer.cs each time i update the dbml?
i believe there should be a better way to do it

I have a database table called Animals which I drag on to my Linq to SQL DBML file.
This creates me a class called Animal.
I then create a class to extend it, like so:
public partial class Animal{
//my extra code here
}
But what I also want to do is have a class like this:
public class Zebra : Animal{
//even more extra code here
}
The trouble is I get an InvalidCastException from my repository, when I do this:
Animal a = dataContext.Animals.Where(c=>c.id.Equals(id)).SingleOrDefault();
return (Zebra)a;
I've stripped back my classes to the point where they're completely empty in an attempt to work why it doesn't work. To no avail.
This casting process did used to work in the non-LINQ-2-SQL project that I'm switching to MVC/LINQ.

I have added a partial class to one generated by the Entity Framework. I wanted to add a calculated field that I could bind to my GridView. However, when I try to access the new property, I get an error message that this is a limitation to Entity Framework.Are there any work arounds to accomplish this?
