Most often I use it when I am accessing a property of a composite control that depends on a child control. But I have also added it to OnInit of a control so I could make sure a hidden field was added correctly. Just a minute ago I called it in RenderControl because I was having an issue rendering a calendar extender and it fixed it. I am starting to get a little confused on when I need to and when I don't need to call EnsureChildControls and when I should call it. Any pointers are welcome. Thanks!
