日历控件的多选通常在开发当中，我们会根据功能需求来做日历这个功能，这个功能也是每个人必不可少要掌握的，今天就来和大家共同研究下日历，其实也比较简单，直接上步骤先来张效果图 1、基础类 package com.example.android_mzsz.utils; import android.content.Context; import android.graphics.Canvas; 阅读详情

1、我的那个星期怎么只显示“星”，能不能让它显示一、二、三、四、五、日
2、怎么让星期的每周显示不同颜色，我的意思是我已经得到每月每周的区间日期，可是我怎么让日历控件每个区间日期显示颜色都不一样呢？
3、我要在选择日期区间的任意天数都要保存星期天的日期，这个好像直接赋值就行了，是不是这样啊。

油气井管柱力学发展油气井管柱力学发展 1 石油管柱力学问题的发复杂性 1）油气管柱动力学的非线性钻井中钻柱在重力、钻压、扭矩、钻井液浮力和井壁约束等作用下，产生三维变形。一方面随井眼轴线的弯曲而弯曲，这一变形被称为管柱的初位移；另一方面，管柱在运动过程中相对井眼轴线也有变形，这种变形被称为计算位移。管柱大变形主要表现在初位移部分，计算位移相对很小。大曲率井眼中管柱产生大挠度，但管柱很长且柔软性较好，变形一般仍保持... 阅读详情

up以下~！
我现在最郁闷的是怎么不用sql语句实现一个日期区间的计算？意思是说用日历控件得到日期区间，然后点击这个区间的日期得到的都是这个日期区间的开始和结束日期

SelectedDates是做什么的好像是个数组把~！怎么用没看明白

能显示，不过是取巧的办法，我曾经的做法是控件不显示上边星期栏，自己做一个table显示

呵呵，多研究研究它的属性就会明白了

问题1:
没有属性可以改，应该算是Calendar控件的一个BUG，我研究过，它完全是根据英文版的改过来的，所以，只显示星。所以我也是把head 给隐藏了，自己做了个Table显示星期，最上端，自己定义导航按钮。

问题2 ：
在事件private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
//m_date 为自己计算的日期
if(e.Day.Date == m_date)
{
e.Cell.BackColor = System.Drawing.Color.LightCyan;
}
}

1. 控件有几种格式，你选择的格式不同显示的标题不同
2.添加Calendar控件的 OnDayRender 事件

<asp:Calendar OnDayRender="OnDayRender" RunAt="server" />
.
.
.
void OnDayRender (Object sender, DayRenderEventArgs e)
{
//再这里添加修改颜色
if (e.Day.Date.Month == 1 && e.Day.Date.Day == 21)
{
//...
}
if((int)(e.Day.Date.DayOfWeek)==5) //星期六
{
e.Cell.BackColor =System.Drawing.Color.Gold;
}

}
