Asp.net 在asp:calendar控件上禁用未来日期

如何在

asp:calendar

控件上禁用未来日期

例如，今天是2013年10月22日，我想禁用10月23日以后的日期，

并在当前日期时重新启用它们。

您需要使用DayRender方法

C#代码隐藏

    public void Calendar1_DayRender(object o, DayRenderEventArgs e)
            {


                e.Cell.BackColor = System.Drawing.Color.Empty;
                e.Cell.ForeColor = System.Drawing.Color.DarkRed;

                //if the days are not part of the current month
                if (e.Day.IsOtherMonth)
                {  
                    e.Cell.Text = "";
                }
             }

public void Calendar1_DayRender(object o, DayRenderEventArgs e)
        {


            e.Cell.BackColor = System.Drawing.Color.Empty;
            e.Cell.ForeColor = System.Drawing.Color.DarkRed;

            if (e.Day.IsToday)
            {
                e.Cell.BackColor = System.Drawing.Color.Blue;
            }
            else
            {
                e.Cell.Text = "";
            }
        }

然后在日历中，您需要放置

ASP

<asp:Calendar ID="Calendar1" runat="server" Height="145px" Width="77px" OnDayRender="Calendar1_DayRender"></asp:Calendar>

您可以使用此技巧禁用日历控件中的未来日期

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{

  if (e.Day.Date > DateTime.Today)
  {

    e.Day.IsSelectable = false;
  }

}

}
