@Tim Schmelter

我不得不因为如果我在特殊的日子将数据插入我的日历中，如果我点击那天而不是它的节目，它将不会直接显示我的插入数据但是我不想这样我这样做

protected void todoSrc_Deleted(object sender, SqlDataSourceStatusEventArgs e)
{
    Refresh();
}
protected void todoSrc_Updated(object sender, SqlDataSourceStatusEventArgs e)
{
    Refresh();
}

private void Refresh()
{
    Response.Redirect(Request.RawUrl);
}

我不确定这是否是原因，但您应该仅在!Page.IsPostBack时执行日历的默认初始化。

if(!Page.IsPostBack){
        if (Calendar1.SelectedDate == DateTime.Today)
        {
            Calendar1.SelectedDate.Date.ToShortDateString();
        }
        _scheduleData = GetSchedule();

        Calendar1.Caption = "<br/>Het is vandaag:<br />" + DateTimeOffset.Now.LocalDateTime.ToShortDateString() + "<h1>Plan School Activiteiten</h1>";

        Calendar1.FirstDayOfWeek = FirstDayOfWeek.Sunday;
        Calendar1.NextPrevFormat = NextPrevFormat.FullMonth;
        Calendar1.NextPrevStyle.CssClass = "NextPrevMonthText";
        Calendar1.TitleFormat = TitleFormat.MonthYear;
        Calendar1.TitleStyle.CssClass = "TitleStyle";
        //Calendar1.TitleStyle.BackColor = System.Drawing.Color.Transparent;
        Calendar1.ShowGridLines = true;
        Calendar1.DayStyle.HorizontalAlign = HorizontalAlign.Left;
        Calendar1.DayStyle.CssClass = "Daysoftheweek";
        Calendar1.DayStyle.VerticalAlign = VerticalAlign.Top;
        Calendar1.DayStyle.Height = new Unit(75);
        Calendar1.DayStyle.Width = new Unit(100);
        Calendar1.TodayDayStyle.CssClass = "Today";
        Calendar1.TodaysDate.ToShortDateString();
        Calendar1.VisibleDate = Calendar1.TodaysDate;
        Calendar1.SelectedDayStyle.CssClass = "SelectStyle";
        Calendar1.SelectedDayStyle.BackColor = System.Drawing.ColorTranslator.FromHtml("#ffea44");
        Calendar1.SelectedDayStyle.ForeColor = System.Drawing.ColorTranslator.FromHtml("#000");
}
