使用日期控件
使用日期控件,使用onclick事件在textBox中下拉显示. 
出现下方的textBox控件覆盖了日期控件. 
弹出日期控件自然是需要在页面的最上层显示的.请问这个问题如何解决.

------解决方案--------------------
<div id= "cal " style= "position:relative; top:0; left:0; z-index:1; overflow:auto; display:none "> 
<asp:Calendar ID= "Calendar2 " runat= "server " DayHeaderStyle-Font-Size= "12px " BorderColor= "#666666 "
FirstDayOfWeek= "Monday " NextMonthText= "Next " PrevMonthText= "Prev " TitleStyle-BackColor= "#ffba00 "
BackColor= "#FFCD4A " Width= "192 " DayHeaderStyle-Font-Bold= "false " DayHeaderStyle-VerticalAlign= "bottom " 
SelectedDayStyle-BackColor= "#ffba00 " SelectedDayStyle-BorderWidth= "1 " SelectedDayStyle-BorderColor= "#666666 " 
TodayDayStyle-BackColor= "#ffffff " TodayDayStyle-BorderColor= "#666666 " TodayDayStyle-BorderWidth= "1 " 
SelectionMode= "Day " OnSelectionChanged= "select_date " OnVisibleMonthChanged= "MonthChanged "> </asp:Calendar> 
</div> 


onclick textbox时用js设置div的display=block
抢个SF
