I have an asp.net mvc project, its build just from views, controllers, models, and other files. I have any codebehind file in my views. Does it makes sense to create them for using sometime? Is it some situation when they giving more abilities and advantage for developer?

perhaps it's my exposure to php frameworks, but asp.net mvc makes perfect sense to me. the logic is there to build a well organized website, and it really doesn't seem more difficult than using web forms. is it wise for me to jump straight into asp.net mvc from php or would you recommend I learn web forms first?
View 1 RepliesWe have a WebForms based web application with these properties:
Large Business Object Framework (Close knit DAL / Business Objects / Serverside Validation, similar to CSLA) Precompiled and placed in the Bin folder. Uses a lot of UserControls.
Looking at overviews of MVC it seems there is a distinctive split on how the code is split up, there is no Session State (which seems odd, but possibly ok if the website is primarily serving content?) and it appears constructing pages looks similar to classic asp (use of <% %> tags)
Do I have the wrong interpretation of MVC? Is MVC just a specific architecture, or is the way things will be going and WebForms will eventually be dropped? How does one split the M-V-C when an existing Business object Framework exists? Why is there no session state? Do UserControls work in MVC? I realise this could be subjective, so mostly looking for your comments on the subject to make my up my own mind.
If this is not the appropriate forum for this I didn't see any linq specific forum listed.
I am about to start a new project and I would like to use it as an opportunity to update myself with the newer technologies, like ajax and linq.
All my database CRUD operations will be done by sql stored procedures, does linq still make sense when doing that? I watched a couple introductory videos on linq and none of them dealt with stored procedures, thats why I'm wondering.
In case of C#, when we code a keydown event which usually works in server side, what happend? Can PHP do that? or should work only in javascript which is client side?

I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

I have an ASMX Web Service that has its code entirely in a code-behind file, so that the entire contents of the .asmx file is:
<%@ WebService Language="C#" CodeBehind="~/App_Code/AddressValidation.cs" Class="AddressValidation" %>
On my test machine (Windows XP with IIS 5), I set up a virtual directory just for this ASP.NET 2.0 solution and everything works great. All my code is separated nicely and it just works.However, when we deployed this solution to our Windows Server 2003 development environment, we noticed that the code only compiled when all of the code was dropped directly into the .asmx file, meaning that the solution didn't work with code-behind. We can't figure out why this is happening.
One thing that's different about our setup in our development environment is that instead of creating a separate virual directory just for this solution, we dropped it into an existing directory that runs a classic ASP application. So here we have a folder with an ASP.NET 2.0 application within a directory that contains a classic ASP application. Granted, everything in the ASP.NET 2.0 application works if all of the code is within the .asmx file and not in code-behind, but we'd really like to know why it's not recognizing the code-behind files and compiling it correctly.
Recently, I have read an excellent tutorial from asp.net, MVC music store.

It is very powerful!
