GroupBox in WPF can only contain one element?

Question

It seem that GroupBox can only contain one element, if I place more than one it\'s won\'t go inside(or get deleted in blend).

Is this by design or am I doing something w

Answer 1

You must drag the items: textbox INTO the groupbox and must only have a single groupbox. Cannot drag more than a single groupbox per linear coordinate for it to work. Can have multiple groupboxes on a page, but not more than a single column wide or you will be limited with only having a single item being added to the groupbox.
