我一直在研究一个项目，并且遇到了一个问题，即，我能够使用asp.net日历控件选择第一个和最后一个日期，但我希望使用日历程序" title="扩展程序">扩展程序在日历扩展程序中添加天数

如下所示的代码是用于控制压延..please我提供所需修改..............

protected void Calendar1_SelectionChanged(object sender, EventArgs e) 
    { 
    Calendar1.SelectionMode = CalendarSelectionMode.DayWeek; 
    //ArrayList selectedDates = new ArrayList(); 
    string s = Calendar1.SelectedDate.ToShortDateString(); 
    DateTime today = DateTime.Parse(s); 
    DateTime firstDay = today.AddDays(-(double)(today.DayOfWeek)); 
    DateTime lastDay = today.AddDays(6 - (double)(today.DayOfWeek)); 
    for (int loop = 0; loop < 7; loop++) 
     Calendar1.SelectedDates.Add(firstDay.AddDays(loop)); 
    lblStartOfWeek.Text = firstDay.ToLongDateString(); 
    lblEndOfWeek.Text = lastDay.ToLongDateString(); 
    lblStartOfWeek.Visible = true; 
    lblEndOfWeek.Visible = true; 
    checkLessonPlan(); 
    }

回答：

protected void Calendar1_ontextchanged(object sender, EventArgs e) 
{ 
    string numberofdays= Convert.ToDateTime(this.TextBox1.Text).DayOfWeek.ToString("d"); 
    DateTime select = Convert.ToDateTime(TextBox1.Text); 
    lblStartOfWeek.Text = select.AddDays(-Convert.ToInt32(numberofdays)).ToString("dd MMMM yyyy"); 
    lblEndOfWeek.Text = select.AddDays(6-Convert.ToInt32(numberofdays)).ToString("dd MMMM yyyy"); 
}
