A control cannot modify its parents' control collections.

[Alexandru Nedelcu]

Hi!!!

I'm trying to add a UserControl created using the
Page.LoadCotnrol("test.ascx") method to a Page's Control collection and
the exception I get is ( the complete stack trace):

[HttpException (0x80004005): A control cannot modify its parents'
control collections.]
