MonthCalendar FirstDayOfWeek

Does anyone know how to set the first day of the week to Monday instead of Sunday for a MonthCalendar in a grid control. I''ve tried the code before with no success.

Thanks,
Todd

this.gbcDate.MappingName = "AirDate";
this.gbcDate.StyleInfo.CellType = "MonthCalendar";
this.gbcDate.StyleInfo.CellValueType = typeof(System.DateTime);

System.Globalization.CultureInfo cultureInfo = new System.Globalization.CultureInfo("en-US");
cultureInfo.DateTimeFormat.FirstDayOfWeek = DayOfWeek.Monday;

this.gbcDate.StyleInfo.CultureInfo = cultureInfo;
this.gbcDate.StyleInfo.Format = "d";

OK, got it. Sorry.

private void dgAiringTime_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e)
{
GridDropDownMonthCalendarCellRenderer cr = this.dgAiringTime.CurrentCell.Renderer as GridDropDownMonthCalendarCellRenderer;

if (cr != null)
{
MonthCalendar calendar = cr.DropDownContainer.Controls[0] as MonthCalendar;

calendar.FirstDayOfWeek = Day.Monday;
}
}
