ASP.NET CompareValidator cannot find ControlToCompare

I have a form with custom controls. Each custom control contains a TextBox.
When I attempt to dynamically add a CompareValidator to a TextBox which
compares to a TextBox within the other custom control .NET throws the
exception: "Unable to find control id 'txt_element71' referenced by the
'ControlToCompare' property of 'valCompare_txt_element72'."

It appears that .NET can only support setting the ControlToCompare to a
control within the same control heirarchy. Is this true?

That's affirmative.

There are 3rd party controls which do this. The one I'm aware of is
http://www.peterblum.com/vam/home.aspx though it isn't free. My guess is
there are other ones as well.

Thank you Karl.
Any plans for supporting this in the future?
