I have a control that wraps around other controls:

<CN:ParentControl runat = "Server">
    <SUB:ChildControl runat = "Server" />
    <SUB:ChildControl runat = "Server" />
    <SUB:ChildControl runat = "Server" />
</CN:ParentControl >

Under certain conditions in ParentControl I set its visibility to false,
which of course hides the other three controls. This is the desired effect.
When I look at the control tree using Trace, I can still see the
SUB:ChildControl's(which makes sense).

However, for performance purposes, if you can't see it, it seems like a
waste to let it continue processing. Is it possible to disallow child
control processing if a certain parameter is met in the parent? Any
examples?

Thanks,
Scott

How are you building the children? If you were to use a custom control =
builder (or whatever it is called) you should be able to do checks and =
skip those children if required.

I am not handling the building of the childcontrols myself. I have used
built a controlbuilder in the past, so maybe I will check that out.

In this case though, the childcontrol could be anything from plain text to a
usercontrol. My ParentControl functions properly, I just thought it would be
a good idea performance wise to not build the childcontrols if they aren't
going to be rendered back to the client.

Thanks for the suggestion.
