Very, very cool: Fixing the IExtenderProvider in Visual Studio's ASP.NET designer.
The fact that Extenders Providers don't work in ASP.NET has been bothering me for a very long time, and this article shows a way how to fix that once and for all. And all it needs is an extra attribute on your IExtenderProvider class. Sweet!
In case you're wondering: extenders aren't supported in ASP.NET because the team didn't really see a scenario for it. Mainly because they're mostly used to hook into control events and that just doesn't really happen as much on ASP.NET like in WinForms.
But you could still do useful things with it (translation and data binding jump to mind) so I was really bummed about that. I talked to Scott Guthrie about it on the PDC03, explained a few reasons why I'd use them and he agreed I had a good point but it was unlikely that they would actually implement it.
