Code Behind Question

Chris Kettenbach

Hi I am designing an ASP.net app. Just wanted some opinions on code behind
options. My idea is to have a code behind file that the controls will
reference and have ascx files for the controls. Then have the aspx pages
call the controls. Is this a good approach? I wanted to throw all my
business logic in to the code behind file and then on the aspx pages that
use the controls just refernce the ascx files. Is this the correct
approach? Should I bypass the ascx controls if they are not fancy customer
controls just like a datagrid? Also I connect to SQL back end in the app
and get different data for some of the datagrids that will be on the main
page? Is it better to put the ADO.net connection logic in to the ascx
files? or better to use the Code Behind? Thanks for any opinions.

Regards,
Chris

Do not think of CodeBehind as a file, or you're already in trouble. It isn't
a "file" to your application. It is a class definition. It is the class
definition for a given Page. The class definition is simply split into a
Template (.aspx) and a class definition.

A Page is a System.Web.UI class, which means that it is a User Interface. As
such, it isn't a good idea to put much (if any) business logic into it. Your
business logic should reside in Business classes, classes that work with
data and have no User Interface. The Page is then the User Interface, with
all the User Interface elements in it, and the only logic in the Page should
deal with presenting the data from the data classes in the page, and
allowing the User to interact with it. The Page should interact with the
business objects via the business class programming interface.

Future reuse of code

by: James Cameron | last post by:

Hi I'm developing a program and the client is worried about future reuse of the code. Say 5, 10, 15 years down the road. This will be a major factor in selecting the development language. Any comments on past experience, research articles, comments on the matter would be much appreciated. I suspect something like C would be the best based on comments I received from the VB news group. Thanks for the help in advance James Cameron

I am just trying to decide whether to split my code and uses code behind. I did it with one of my pages and found it was quite a bit of trouble. I know that most people (and books and articles) like it because you can split the code from the design. That is logical. But if you are the only one working on the code, it seem a little overkill. I use Dreamweaver to do my design and find it a bit of a hassle to have multiple files open...

Design flow for Code-behind

by: tshad | last post by:

Many (if not most) have said that code-behind is best if working in teams - which does seem logical. How do you deal with the flow of the work? I have someone who is good at designing, but know nothing about ASP. He can build the design of the pages in HTML with tables, labels, textboxes etc. But then I would need to change them to ASP.net objects and write the code to make the page work (normally I do this as I go - can't do this...

Where do you store your code-behind files and user controls?

Hello, I am just looking at VWD and seeing what needs doing to take an existing site I've written by hand and importing it into VWD. I've already discovered that I need to rename my code-behind files to match the .aspx file name so VWD will tie the two together, and I'm now wondering what to do about the location of the code-behind files. Is there any set convention for where the code-behind files live? I have been putting them in the...

Is it a good idea to put all code-behind in App_Code folder?

Hi, when I add a new page in my asp.net 2 project and put some controls there, everything works fine until I move the code behind into App_Code folder.--When I compile , it tells me that control "not exist in the current context". I thought putting code behind in App_Code folder is the recommendation for asp.net 2. In order to do so, I just simply remove the codefile attribute in @page. Maybe my perception of putting all code in...
