private void SetValue()
{
    // Use name to access the cell.
    this.gcCalendarGrid1.Template.Content[2, 0].Name = "cell1";

    // Set value to a cell in today.
    this.gcCalendarGrid1[DateTime.Today][1, 0].Value = "abc";
    this.gcCalendarGrid1[DateTime.Today]["cell1"].Value = "abc";

    this.gcCalendarGrid1[yearlyDate]["cell1"].Value = "abc";

    // Set value to the cells in a monthly weekday recurrence.
    IEnumerable<DateTime> monthlyWeekday = DateRange.CreateMonthlyWeekDayRecurrence(new DateTime(2014, 1, 1), DayOfWeekInMonth.Last, DayOfWeek.Friday, 1, new DateTime(2014, 12, 31));
    this.gcCalendarGrid1[monthlyWeekday][1, 0].Value = "abc";
    this.gcCalendarGrid1[monthlyWeekday]["cell1"].Value = "abc";
