I've set up a test. One form, one pageframe.
On page3 first activate, a container (class with one textbox) is added and textbox' controlsource is set
Subsequent activates of page3 call container.activate() which does 'this.Refresh()'

On the form I have also a commandbutton which changes the table (controlsource of container's textbox in page 3)

Deactivating page3, clicking the commandbutton, and then activating page3 is showing the correct value in the containers textbox. - as expected

The container's textbox' Refresh() is called when container.Refresh() is called - as expected

The only thing I can think of is that when you call your containers.Activate(), its parent page is not active - yet

That is the only scenario that (1) does not trigger the container's textbox refresh (since the page is not active) and (2) would explain why a subsequent page.Refresh() or thisform.Refresh() works in your case. The page will be active by then - I guess
