Hiding the Focus Rectangle
Overview
You can specify that edit mode is always on in all sheets in the control. When edit mode is always on, the sheets act like forms, where the user can enter data in any data field without turning edit mode on, and the focus rectangle is not displayed. You can also hide the focus rectangle with the active cell highlight feature. Set the sheet before setting the active cell highlight if there are multiple sheets.
