Hi all,

Is there a way to prevent the user from entering negative number into a form besides using procedure Key?
(I know I can validate on Exiting/OnKillFocus afterwards as that is my current workaround)

Code:
Use DfAllEnt
Object oPanel is a Panel
    Set Size to 300 300
    Object oForm is a Form
        Set Numeric_Mask 0 to 6 2 "###,###.00"
        // Set Numeric_Mask 0 to 6 2 "###,###.00;###,###.00" // Doesn't work as it masks for display. User can still enter in negative number
    End_Object
End_Object
Start_UI
