Subj : How can JS intercept relayout calls?

Hi,

I've written an ASP.NET ComboBox, and mostly it works pretty well in IE
and Mozilla.  (I'm using Firefox 1.0, by the way.)

I've just come across this problem though.  First of all, here's an
example of the problem in action:

http://www.opinionatedgeek.com/DotNET/products/powerpack/ComboProblem.aspx

If you click the button, it dynamically un-hides a DIV element, which
dynamically changes the layout.  However, since I've used a clipped
absolutely-positioned SELECT to create the dropdown part of the
ComboBox, it's still stuck in the original position.

I want it to follow the textbox part of the ComboBox, so it looks just
the way it should.

I /think/ I want a Javascript event I can hook into to say a re-layout
has just occurred.  Or the element I'm interested in has moved.  Or
something.  (IE has onmove and onresize, which I can use - check out
the same URL in IE.)

Alternatively, I'm happy to re-jig things so they work properly in
Mozilla, whatever it is I need to do.  I just don't know what.  (I
can't use relative positioning, because then I can't clip it, but I
can't see any way of finding out I need to re-calculate the absolute
positioning.)

I want it to work as well in Firefox as it does in IE.  Any thoughts or
ideas appreciated.

Cheers,

Geoff
