ASP.NET v.2 code behind

[Gary Hyslop at home]

After converting my first ASP.NET 1.1 project to 2.0, I discovered that one of my button's onclick handler wasn't working. I then proceeded to inspect the InitializeComponent code to find that it was empty. Also there was no declartion of the button control -- or any other control present. Where does ASP.NET v2.0 put this code? Also, is there any way of fixing my problem in code or do I have to delete the button and re-create it so that ASP.NET v2.0 can do it's "under the hood" stuff right? JSaybrook

The reason this works has to do with the partial keyword applied to your codebehind class. In addition to turning your .aspx file into a class definition with methods for rendering the page, as it has always done, ASP.NET now also generates a sibling partial class for your codebehind class that contains protected control member variable declarations. Your class is then compiled together with this generated class definition and used as the base class for the class generated for the .aspx file. The end result is that you essentially write codebehind classes the way you always have, but you no longer have to declare (or let the designer declare for you) member variable declarations of server-side controls.

My basic problem is that one of my buttons, that used to work in the 1.1 version no longer works after the application was converted to 2.0. By that I mean that that the OnClick event doesn't fire. In 1.1 the probable culprit would be a missing "wireup" in InitializeComponent. Now the only reference to the button control that I control appears to be the one in the "html" in the aspx page. Would it help to delete this reference and re-create it? According to what you say it wouldn't appear to matter whether I used an editor or the designer to do this. jsaybrook

Are you using the CodeFile keyword in your @Page directive? What about runat="server" in the button? (Just making sure)
