asp.net building controls : Custom Server Control works on page but not User Control...why?

I've taken a quick look at the control and may look more deeply later. It
looks pretty nice, and we might need such a thing, so your offer is
tempting. My one negative comment so far is that your "unregistered" message
box displays too often. It gets in the way of testing the control. I would
think that once per activation, or once per hour would be enough.

For the moment, I'll say that I recently had trouble with a complex control,
when I made assumptions about the order in which events fired. I got out of
this mess by instrumenting the hell out of the code, adding Page.Trace.Write
statements to every possible overload of a Control method and then having
the method call its base class version. After simplifying the problem to its
smallest possible broken version and poring over the event traces, I finally
tracked down my problem. Maybe the same technique will work for you.

Note that Page.Trace cannot be referenced in design mode, so you'll want to
create your own "PageTraceWrite" method which checks for design mode before
even referencing "Page.Trace", much less calling Page.Trace.Write.

How are you trying to get the value? Would it have any impact on the program
logic that Load event on the containing Page fires before Load on controls
it contains?

I'm developing the DevEdit.NET server control (an online HTML editor -
www.devedit.com) but there's an extremely bizarre bug. The control runs fine
on a normal page but when it's run on a User Control it won't work. The
control renders fine and has no errors but when I try to retrieve the value
of it when the page is posted back it just returns its original value rather
than the one that the user entered.

If someone can help me fix this problem (you can download the trial version
from the site) I'm sure I can arrange for a free copy of this control for
you.

I'm not sure I understand what you mean. You can download the trial version
of the control which has the same problem from www.devedit.com and it comes
with the source code provided.

Regards,
John
