推荐答案

先添加.dll - RJS.Web.WebControl.PopCalendar.Net.2008.dll

然后添加源代码:

<asp:TextBox ID="DepartureDate" runat="server"></asp:TextBox>
&nbsp;&nbsp;&nbsp;
      <rjs:PopCalendar ID="PopCalendar1" runat="server" Control="DepartureDate" 
            Format="mm dd yyyy" 
            InvalidDateMessage="The date value entered is invalid." RequiredDate="True" 
            RequiredDateMessage="You must enter a date value." From-Date="" SelectWeekend="True" 

            />
    <br />
    <br />
    <br />
    <asp:TextBox ID="ReturnDate" runat="server"></asp:TextBox>
&nbsp;&nbsp;&nbsp;&nbsp;
     <rjs:PopCalendar ID="myReturnCal" runat="server" Control="ReturnDate" 
            Format="mm dd yyyy" 
            InvalidDateMessage="The date value entered is invalid." RequiredDate="True" 
            RequiredDateMessage="You must enter a date value." 
            From-Control="DepartureDate" From-Date="" From-Increment="1" 
            />
    <br />
      <asp:Label ID="Results" runat="server"></asp:Label>
        <rjs:PopCalendarMessageContainer ID="PopCalMessagesForDeparture" runat="server" 
            Calendar="myDepartureCal" />
        <rjs:PopCalendarMessageContainer ID="PopCalMessagesForReturn" runat="server" 
            Calendar="myReturnCal" />
