Controls Not Instantiated on UserControl

[Eric Robishaw]

What's the deal?

If I place a control, a standard Web control (like a panel, or server-side
Table), onto a Web User Control I've created, I can't access the control
from the Code-Behind code.

In the Page_Load event of the Web User Control, if I say:

PlaceHolder1.Controls.Add (new LiteralControl ("<img src='bla.gif'>"));

I get an error: Object null. And sure enough, PlaceHolder1 has no value
set.

If I do a "This.Controls.Count" I get a big fat zero.

What's the deal.

Desperate and annoyed.

Check to see if the control you added has the declration. Vs.net
automatically puts this declaration for you, unless you added this control
in html view and then switched to your code behind class.

Try doing the action in page_init.

i have no idea why, but it works for me!

My lack of understanding of how asp.net works i expect!
