我需要asp.net日历控件的帮助 [英] i need help for asp.net calendar control

问题描述

亲爱的家伙。我必须限制访问或选择日历控制中任何前一天，月，年的日期，除了今天或明天之后的任何一天

 受保护 无效 Calendar1_DayRender（ object  sender，System.Web.UI.WebControls.DayRenderEventArgs e）
 
 {
 
  if （e.Day.Date.ToShortDateString（）<  = DateTime.Now.ToShortDateString（））
 
 {
 
 e.Cell.BackColor = ColorTranslator.FromHtml（ ＃ a9a9a9\" ）; 
 
 e.Day.IsSelectable =  false ; 
 
} 
 
} 

这种方法只是改变背面颜色而不是禁用选择。我先提取了几天单独使用整数，因为如果也有一些错误。无论如何;它不起作用

  protected   void  Calendar1_DayRender（ object  sender，DayRenderEventArgs e）
 {
 DateTime pastday = e.Day 。日期; 
 DateTime date = DateTime.Now; 
  int  year = date.Year; 
  int  month = date.Month; 
  int  day = date.Day; 
今日DateTime =  new  DateTime（年，月，日）; 
  if （pastday.CompareTo（今天）<   0 ）
 {
 e.Cell.BackColor = System.Drawing.Color.Gray; 
 e.Day.IsSelectable =  false ; 
} 
} 

这种方法不起作用

解决方案

不要使用此控件。



使用此功能！ [ ^ ]

问候......：笑：

Dear fellows.I have to restrict access or selection to the date of any previous Day,Month,Year in the Calendar Control except today's or any day(s) after tomorrow

protected void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)

{

    if(e.Day.Date.ToShortDateString() <= DateTime.Now.ToShortDateString())

    {

        e.Cell.BackColor=ColorTranslator.FromHtml("#a9a9a9");

        e.Day.IsSelectable=false;

    }

}

this approach just change the back color and not disabling selection.I first extracted the days in integers separately because if also has some errors.Anyways;it doesn't work

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
    {
        DateTime pastday = e.Day.Date;
        DateTime date = DateTime.Now;
        int year = date.Year;
        int month = date.Month;
        int day = date.Day;
        DateTime today = new DateTime(year, month, day);
        if (pastday.CompareTo(today) < 0)
        {
            e.Cell.BackColor = System.Drawing.Color.Gray;
            e.Day.IsSelectable = false;
        }
    }

that approach didn't work as well

解决方案

Dont use this control.

Use this![^]

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
     {
         if (e.Day.Date < DateTime.Now)
         {
               e.Cell.Text = e.Day.Date.Day.ToString();
               e.Cell.BackColor = System.Drawing.Color.Gray;
               e.Day.IsSelectable = false;

         }
     }
