To restrict a Calendar control (System.Web.UI.WebControls.Calendar) to a specified range of dates, you can assign the NextMonthText and PrevMonthText fields in the calendar's PreRender method. If the calendar's VisibleDate field is later or equal to the maximum date, set NextMonthText to the empty string. If the calendar's VisibleDate field is earlier or equal to the minimum date, set PrevMonthText to the empty string. Make sure the set the calendar's VisibleDate property in the Page_Load method.



protected void Calendar1_PreRender(object sender, EventArgs e)
{
    int minYear  = 2006;
    int minMonth = 1;

    int maxYear  = 2007;
    int maxMonth = 12;

    if (Calendar1.VisibleDate.Year > maxYear || (Calendar1.VisibleDate.Year == maxYear && Calendar1.VisibleDate.Month >= maxMonth))
    {
        Calendar1.NextMonthText = string.Empty;
    }
    else
    {
        Calendar1.NextMonthText = ">";
    }

    if (Calendar1.VisibleDate.Year < minYear || (Calendar1.VisibleDate.Year == minYear && Calendar1.VisibleDate.Month <= minMonth))
    {
        Calendar1.PrevMonthText = string.Empty;
    }
    else
    {
        Calendar1.PrevMonthText = "<";
    }
}

No property for range in canlender control for fix month range

No property for range in canlender control for fix month range, u can achive this only by customized by other property like visible , u take own logic for set visible true or false depend upon that range.
