What is the purpose of CreateChildCont rols()?

[Michael]

Hi,

I'm coding a custom server control, and CreateChildCont rols() is giving me
some pain. I'm just wondering why we have CreateChildCont rols(), and why
this methods seems to be called at different times in the page lifecycle. I
mean the order it is called is not deterministic. Example if not post back,
then my CreateChildCont rols() is being executed before my Load event. But
for post back, my Load event executes before my CreateChildCont rols().

I suppose calling EnsureChildCont rols() will call CreateChildCont rols() if
it has not already been called. But why all this complication? I'm even
thinking about creating my controls in the constructor instead of inside
CreateChildCont rols(); at least this way I know that my controls will have
been created when I need to use them.

Hi Michael,

Here's a good reference for this:

http://msdn.microsoft.com/library/de...nLifecycle.asp

At the bottom, there is a note:

"The CreateChildCont rols method is not listed in the table because it is
called whenever the ASP.NET page framework needs to create the controls tree
and this method call is not limited to a specific phase in a control's
lifecycle. For example, CreateChildCont rols can be invoked when loading a
page, during data binding, or during rendering."
