Vista - A question about new an object.

Dear all:

I wrote an Contorl(called:MyControl) and wrote its controltemplate.
The control has a membe variable MyButton which is point to an button
in the controltemplate. So I wrote the code in the OnApplyTemplate of
MyContorl like this..
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
MyButton = Template.FindName("Button1", this) as Button;
}
Button1 is the name of a button in the controltemplate.

But when I use code to new a MyControl, the OnApplyTemplate doesn't
run it. So the MyButton is null.

What can I do to new a control and get the button of the
controltempate?

Thanks a lot.

Did you ever get this working? My first thought is that OnApplyTemplate
hasn't been called because the template has been applied yet -- the template
isn't applied until the layout system puts that element on the screen as
part of the layout pass. So if the element isn't in the tree yet, or is not
in a visible part of the tree, the template may not have been applied yet.
