At least two ways to handle this:
1) Create a pageframe with two pages, one for each data entry "screen". Then, enable and disable each page according to the screen to be displayed.

2) Hide un-needed items and re-display needed items. Use ThisForm.SetAll() to enable/disable the Visible property of the items.
