C# Ajax日历控件的Ajax日历日呈现事件或如何在Ajax日历中阻止某些日期

禁用ajax日历控件上的日期

protected void CalendarDayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
    // If the month is CurrentMonth
    if (!e.Day.IsOtherMonth)
    {
        foreach (DataRow dr in ds.Tables[0].Rows)
        {
            if ((dr["BookingDate"].ToString() != DBNull.Value.ToString()))
            {
                DateTime dtEvent = (DateTime)dr["BookingDate"];
                if (dtEvent.Equals(e.Day.Date))
                {
                    e.Cell.BackColor = Color.PaleVioletRed;
                   // e.Day.IsSelectable = False;

                }
            }
        }
    }
    //If the month is not CurrentMonth then hide the Dates
    else
    {
        e.Cell.Text = "";
    }
}

我可以用下面的脚本阻止asp日历控件中的日期。 带有图像的示例。。 我正在从数据库中读取预定日期，并用不同的颜色突出显示这些日期。这在asp.net日历中运行良好，但我想在ajax日历控件中实现同样的功能

protected void CalendarDayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
    // If the month is CurrentMonth
    if (!e.Day.IsOtherMonth)
    {
        foreach (DataRow dr in ds.Tables[0].Rows)
        {
            if ((dr["BookingDate"].ToString() != DBNull.Value.ToString()))
            {
                DateTime dtEvent = (DateTime)dr["BookingDate"];
                if (dtEvent.Equals(e.Day.Date))
                {
                    e.Cell.BackColor = Color.PaleVioletRed;
                   // e.Day.IsSelectable = False;

                }
            }
        }
    }
    //If the month is not CurrentMonth then hide the Dates
    else
    {
        e.Cell.Text = "";
    }
}

我需要对Ajax日历控件执行同样的操作

但当我将相同的代码放在Ajax prerender事件下时，我无法做到这一点

    protected void AjaxCalendar_PreRender(object sender, EventArgs e)
    {
        //startdate= enddate="2012-06-25"
        DateTime startDate = Helper.GetUAEDateTime();
        DateTime endDate = DateTime.Now.AddDays(10);

        AjaxCalendar.StartDate = startDate;
        AjaxCalendar.EndDate = endDate;     
//Here i nee code to block date if it is booked in the database 
    }

例如，我看了一下，这样我就可以从代码隐藏中完成，但到目前为止，我还不能用Ajax日历控件完成

protected void CalendarDayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
    // If the month is CurrentMonth
    if (!e.Day.IsOtherMonth)
    {
        foreach (DataRow dr in ds.Tables[0].Rows)
        {
            if ((dr["BookingDate"].ToString() != DBNull.Value.ToString()))
            {
                DateTime dtEvent = (DateTime)dr["BookingDate"];
                if (dtEvent.Equals(e.Day.Date))
                {
                    e.Cell.BackColor = Color.PaleVioletRed;
                   // e.Day.IsSelectable = False;

                }
            }
        }
    }
    //If the month is not CurrentMonth then hide the Dates
    else
    {
        e.Cell.Text = "";
    }
}

我正在从数据库中读取值&阻塞已经预订的日期

我非常感谢你在这方面的帮助
