A property of a control should describe the control.
Your controls on your forms play different roles. Depending of the role of a control you take different actions. So name the role/type of the control and your code will be clear like a full ligth good german beer ;)

PROC Refresh
#DEFINE EDITABLEDATA 1
#DEFINE NAVIGATIONAL 2
#DEFINE SAVECANCEL 3
#DEFINE OTHER 4


WITH This
DO CASE
CASE ISNULL(.type)
* nothing to do
CASE .Role = EDITABLEDATA
* set enabled state to the same value of forms editmode
.Enabled = ThisForm.lEditMode
CASE .Role = NAVIGATIONAL or .Role = SAVECANCEL
* set enabled state to the opposite value of forms editmode
.Enabled = (NOT ThisForm.lEditMode)
