Extender Provider

[JezB]

Could anyone tell me how to implement an extender provider for ASP.NET ? I
have done this successfully for windows forms but all the online
documentation tells us is :

The implementation of an extender provider for Windows Forms controls is
different from that for ASP.NET server controls.

check one of my few articles..
http://www.codeproject.com/aspnet/RaoCSSProvider.asp
it writes an extender provider to set CSSClass property.

hth,

In this article you seem to be using an additional property as an
alternative to setting the CssClass property. But I want a completely new
property, not linked to any existing property. The problem I'm having is
that, while I can see and set the new property I create in visual studio, at
run time the values are not read and when I revisit visual studio the values
I set are gone.
