TTMSFNCDateTimePicker.AllowNumericNullValue Property

When True, empty numeric date or time input is accepted without forcing a numeric value.

API unit family: TMSFNCDateTimePicker Declaring type: TTMSFNCDateTimePicker Inherited from: TTMSFNCCustomDateTimePicker Type: Boolean

Syntax

property AllowNumericNullValue: Boolean;

Default: True

Remarks

The default value is True. When enabled, an unset date or time (numeric value 0) is accepted and displayed as blank instead of being coerced to a concrete date or time value. Set this to False when the application always requires a fully specified date and time. This setting is forwarded to the embedded date picker and to whichever time picker is active (analog or digital). Call Clear to reset the control back to the blank state.
