Hi all,
What is the recommended way to add child controls *around* existing
child controls in the CreateChildCont rols method (e.g. table, row and
cell controls for layout purposes)?
Is the best way to keep a reference to the existing child controls,
clear the Controls collection and then re-add everything along with the
layout controls, or insert the layout controls around the existing
controls in the existing Controls collection?
Thanks,
Paul

If I try to modify the Controls collection, I get a "The Controls
collection cannot be modified because the control contains code blocks"
error because my controls contain literal content (i.e. <%=
SomeValue%>). If I change the literal content to a <%# %tag it
doesn't get picked up and is rendered empty.
Is there any way to insert layout controls around the existing controls
and preserve the literal content?
Any help would be appreciated. I'm stuck on this one.
Thanks,
Paul

Hello,
I have a composite WebControl that I'm dynamically instantiating at
runtime using Reflection. When I create a new instance of my control I
immediately iterate through it's child control collection (it has
about 4 child controls). The problem is none of these controls are
loaded or accessible when I create the instance since, I believe, they
are created by the server at a later point in time. How could I force
my composite control...

Hey guys,
I am working on a web custom control that basically draws a table (ASP
Table) with a few child controls in the cells.
I have a command button inside one of these cells. The problem I am running
into is that I cannot get the click event of this object handled. I have
tried wiring the event with "AddHandler" among other things and that seems
not to work neither.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
