you can set SelectedDate to the last day of the month that would be calculated like this and then lock the control so that you can not edit or select dates 

DateTime now = DateTime.Now;
var startDate = new DateTime(now.Year, now.Month, 1); // iniciar el primer día de mes
// Establecer esta variable al Calendar
var endDate = startDate.AddMonths(1).AddDays(-1); // este es el último día del mes en curso.
