Web Forms :: Multiple Partial Class Files For A Webform?

View 1 RepliesWeb Forms :: Accessing Variables Containing Usercontrols In A Partial Class
Oct 25, 2010Last 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:

{
SiteUserControls_Message_Create CreateNewMessageUC = Page.LoadControl(CreateMsgControl) as
SiteUserControls_Message_Create; // typecasting the UC

View 4 RepliesJavaScript - Create Css Class On The Fly In Codebehind
Aug 4, 2010I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
C# - Moving Code From Codebehind To Class File?
Jul 17, 2010For some time now I am trying to figure out how I can refactor some of my code to reduce redundancy throughout my application.

This bit of code is used on several pages of my project in the pages codebehind file. How can I move this to a class file. I don't know how to reference an object like a gridview in a class because it does not exist like it does on the actual page.
How To Create Partial Class For UserControl
Feb 24, 2010I 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 RepliesMVC Partial Class For Rule Validation
Jan 4, 2011I 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 class RuleViolation

public RuleViolation (string errorMessage)

}
public RuleViolation(string errorMessage, string propertyName)

CodeBehind Class Not Accessible To Code In App_Code Folder?
Jan 31, 2010I have a PlannerShiftView user control in the root folder of my ASP.NET web site. In my App_Code folder, I have a ShiftViewTemplate class that needs to instantiate a PlannerShiftView (for a TemplateField in a GridView). The problem is, the following code doesn't compile because the PlannerShiftView type is not available in what I deem to be the App_Code 'phantom namespace'.
Please can somebody explain to be what is happening here, as well as what to do. I know I can just move the ShiftViewTemplate out of App_Code, going against convention and without explantion, but that is something of a hollow victory.
MVC :: Computed Column Vs Field In Partial Class?
Jun 28, 2010I 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.
ADO.NET :: DataSet Cleanup Necessary Or Partial Class Handle All
Aug 25, 2010I'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?
MVC :: Redefine Parent's Variables In Partial Class?
Dec 29, 2010i 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 RepliesUnable To Cast A Partial Class Based On LINQ To SQL Object
Mar 28, 2011I 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.
MVC :: Using A Partial View To Render A Section Of A Form Twice
Aug 23, 2010I'm trying to figure out if there's a good way to remove the duplication in this scenario. Here's the model ... a Person that contains two Addresses:
[Code]....
And here's the view:
[Code]....
The entire Address block is duplicated ... one for the Home address, one for the Work address. To remove duplication, I tried factoring out the Address block into a partial view, and doing this in place of the two divs above:
[Code]....
And the page renders fine, but when it gets posted back on form submit, the model binding doesn't work. (Of course it doesn't work ... the <input> tags for the address blocks both have name="Street", so there's no way for the model binder to know whether to shove that into HomeAddress or WorkAddress.)
I read this post:
[URL] but that answer seems most unsatisfactory. Is there a better solution?
