Does anyone know the right incantation to figure that out?

The problem with using script to check whether javascript is enabled is that you only find that out after the script hasn’t run.
Some solutions try the opposite – they use javascript to set a value and then supply Javascript enabled controls if that value is later detected. However, this fails with javascript-sometimes-enabled tools like the Firefox NoScript plugin.
A more robust solution is to always send the plain-HTML compatible control, and then have javascript run on page load to add the correct event handlers/extra DOM elements/etc.
However I don’t know how this fits in with the ASP.NET approach takes to controls.
