Use the UnSelDate property to unselect a date. The SingleSel property specifies whether the control supports single or multiple selection. Use the FocusDate property to specify which date has focus. To work with selected dates, use the following properties:

• SelectDate, retrieves the selected date(s).
• SelCount, retrieves the number of selected dates

The following VB sample unselects all dates:

With Calendar1
    While .SelCount() > 0
        .UnSelDate .SelectDate(0)
    Wend
End With

The following C++ sample unselects all dates:

while ( m_calendar.GetSelCount() > 0 )
	m_calendar.UnSelDate( m_calendar.GetSelectDate( 0 ) );

The following VB.NET sample unselects all dates:

With AxCalendar1
    While .SelCount > 0
        .UnSelDate(.get_SelectDate(0))
    End While
End With

The following C# sample unselects all dates:

while (axCalendar1.SelCount > 0)
	axCalendar1.UnSelDate(axCalendar1.get_SelectDate(0));

The following VFP sample unselects all dates:

with thisform.Calendar1
	do while ( .SelCount > 0 )
		.UnSelDate( .SelectDate(0) )
	enddo
