TDateEdit.OnDateRangeCheck property
Event handler signalled prior to validating and range checking a date value.
Declaration
property OnDateRangeCheck: TDateRangeCheckEvent read FOnDateRangeCheck write FOnDateRangeCheck;Description
OnDateRangeCheck is a
TDateRangeCheckEvent with the
event handler signalled prior to validating and range checking a date value.
It allows the application to perform actions needed before a date value is
potentially updated. An application can implement and assign a routine to the
handler which responds to the event notification.
OnDateRangeCheck is signalled (when assigned) from the DoDateRangeCheck method. It occurs when a new value is assigned to either the MinDate or MaxDate property, and when ButtonClick is called to display the pop-up calendar for the control.
