Silverlight 3/4 Navigation Application - Access child page controls from Parent page

Question

How can I access child page controls from the parent page in a Silverlight 3/4 Navigation Application? I wish to hide an image from the child page when I click a button in the parent page.

Answer 1

I think you can do this by returning a reference to the child page to the parent page when the navigation frame's Navigated event completes. The NavigationEventArgs parameter has a "Content" property which is set to the child page which has just been navigated to.
