Thanks for the reply, but no, I wasn't thinking of the table controls. I was
reading about the new features of .8 and read about other 'virtual' controls
and was excited because I immediately thought about this scenario for their
use. But at the time I read the news, I hadn't even started my conversion to
.8. Now that I have most of my app converted and running, I really need
extremely light wieght controls to get past this problem.
I already have a version of my application where I create ALL the HTML but I
don't have any way to theme it and doing it myself is a step backward.
I can't create any sort of master control because I never know what is going
to be displayed, that is 100% designed by the client using the software, I
simply display what they create. I read in the form/tool definition out of a
db and render it on the fly. Most of the controls are labels and edit boxes,
but they do need to match the theme being used (which is also set by the
user and 'created' at run time). I suppose I could create a subclass of
these basic controls and after they are rendered have the control delete
itself to free up memory. That is if doing a JavaScript delete would kill
the control but not remove the DOM rendering of it?
Thanks,
Jim

Check out the new SourceForge.net Marketplace.
It is the best place to buy or sell services for
just about anything Open Source.
