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.

I have a virtual directory called "MySite.web", and a folder inside this directory called "Sell" where I have my webform Create.aspx and several user controls like CreateAd_CarsAndTrucks.ascx and CreateAd_Motorcycles.ascx.When I try to compile, I get several errors in Create.aspx stating that public partial class Sell_CreateAd_CarsAndTruck, Sell_CreateAd_Motorcycles are not recognized. I am looking at both classes right now (they're in the same folder), so I have no idea why the compiler's not finding them.One odd thing is that, for a moment, it did find one of them (Sell_CreateAd_CarsAndTruck), but from an assembly in either folder "Temporary ASP.Net" under c:Windows or the one in c:usersusername. So I closed my IDE, and deleted both folders. When I open the solution once again, it recreates "Temporary ASP.Net" under c:usersusername and then creates a "App_Web_createad_carsandtrucks.ascx.5a5f4927.ebg000r0.dll" that it uses as definition for the class. But it never uses the actual class as a definition. Basically, when I right-click on the class instance to view its definition, it takes me to metadata.
View 7 RepliesI was just wondering, let's say I created a Method that is in a partial class in App_Code, and this Method would replace the same type of Method that would otherwise be in many files, and so, since it would be called from many files and would probably be called and used very frequently especially because of this. Would this overload this class? I'm not saying what would most likely happen, I'm just asking if it would be even remotely possible?

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 RepliesCurrently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.
I have a webform with codebehind class called ManageCustomers.cs
can I make partial class to that class i've reffered above and How?
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.
View 1 RepliesLast 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 requirement is my code Behind file contains more than 5 thousand line, Now i want to split the code into two file ...The other file also accept the web controls eventsi tried with partial classThis is my Code Behind File

[Code]....
here the Button1_Click method is web control
I have some code in a button_click event in my webform that performs some actions
(writing some xml files).But i wish to place all my XML code in 1 class within my webproject.But how do i exactly acces controls from my webform on this class?nd how do i link those 2 with each other?Ive tried inherit from System.Web.UI.Page in my class but seems thats not quite it.
I'm face of a little problem when using GridView, an EntityDatasource and entity custom properties using a partial class. I'll describe it and I hope that someone has already find the solution because I try to figured out since two days.

Class file Conflicts in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files is preventing me from building the solution. Even though I try emptying out the folder, each time Visual Studio starts the build process, it brings in the class file in to the temp folder with the same folder name. If I restart the machine or leave it overnight, project build without error. Is there anyway to tell Visual studio to delete/ignore/clean any lingering class files that could be in the temp folder?
Clean solution option in VS doesn't work either. Class file in conflict are from the App_Code folder.
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.
What is partial class in c sharp and whats the use of it, how to implement the partial class
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?
I am trying to use a partial class with Data Annotations to validate with the Entity Framework. My partial class looks like:

When i then try to create a product without an entry in Name or Description i get an exception: _Name = StructuralObject.SetValidValue(value, false);
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?
got a question regarding form validation via entity partial class. I created my edmx-file with the Entity Data Model. Now I am trying to validate my form inputs via this partial class:

Edmx file and partial class are in the same namespace. But the partial class does not get fired. My controller file looks like that:

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

View 3 RepliesI have a form which I use to create an issue. WHen you post the form, the form elements are that of a custom DTO. The DTO is then used on my POST method to create the new entity. That all works fine.
However, I want to add the functionality to add multiple issues at the same time from the same view. In effect, the user would click something like 'Report Additional Problem', and an extra set of form fields would appear (I will like use jquery for this, which I don't have an issue with). However, even with just leaving one set of form fields, the user should still be able to create just one issue. But if I habve my post method take a list or array of my DTO, it doesn't work.
Here is the post method before editing:
[Code]....
What I want to do is for this to take an array or list of NewIssueDto. I would then loop through each one in the list and create a new issue from it.
