1.设置日历控件单个日期Table Cell样式 颜色/外观/边距

protected void Calendar1_DayRender(object sender,
    DayRenderEventArgs e)
{
    // Display vacation dates in yellow boxes with purple borders.
    Style vacationStyle = new Style();
    vacationStyle.BackColor = System.Drawing.Color.Yellow;
    vacationStyle.BorderColor = System.Drawing.Color.Purple;
    vacationStyle.BorderWidth = 3;
 
    // Display weekend dates in green boxes.
    Style weekendStyle = new Style();
    weekendStyle.BackColor = System.Drawing.Color.Green;
 
    if ((e.Day.Date >= new DateTime(2000,11,23)) &&
        (e.Day.Date <= new DateTime(2000,11,30)))
    {
        // Apply the vacation style to the vacation dates.
        e.Cell.ApplyStyle(vacationStyle);
    }
    else if (e.Day.IsWeekend)
    {
        // Apply the weekend style to the weekend dates.
        e.Cell.ApplyStyle(weekendStyle);
    }
}

2.设置特定日期不可见/不可选的方法

  protected void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
        {
            if (e.Day.IsOtherMonth)
            {
                Style visible = new Style();
                visible.BackColor = System.Drawing.Color.White;
                visible.BorderColor = System.Drawing.Color.White;
                visible.ForeColor = Color.White;
                e.Day.IsSelectable = false;
                e.Cell.ApplyStyle(visible);
                return;
            }
}

e.Day.IsSelectable = false;这句即是设置不可选择的方法
