Web Custom Control - Tooltip and Rendering within IDE

[Steve R]

I've built a composite web custom control with a lot of
child controls. I assigned ToolTip values to some of
these controls. The ToolTip pop-ups were working fine
until I monkeyed with the order I am rendering the
controls. I had to do this so that the control rendered
properly when a developer drags it from the toolbox onto
the page. Any ideas?

Below is the meat of the code from my user control. The
remainder is private methods.
