All controls are still null after calling EnsureChildControls()?

The way this page is laid out, all of the data is loaded at Page_Init. Well, I have a custom control that is having problems with this though.

I have it on the page like so:

<cc:SomeControl... />

And then I set the value at Page_Init using

MyControl.Value="blah";

Simple stuff..

The Value is an accessor and has something similar to this:

public string Value{
  get...
  set{
    En开发者_如何学运维sureChildControls();
    MyHiddenField.Value=value;
  }
}

and it is here that I have a problem. It says that MyHiddenField is null. Is Page_Init just too early for this? Or is there some other function I need to call?

The fix for this was changing from using a namespace to reference the CustomControl to using a src with a filename

changing this:

<%@ Register Assembly="MyProduct" Namespace="MyProduct.CustomControls" TagPrefix="cc" %>

to this:

<%@ Register src="/CustomControls/MyControl.ascx" tagname="MyControl" tagprefix="uc2" %>
