VS2.0控件之日历《Calendar》C#

2006-06-09 16:49 691 查看

在此之前，我也做过一个VB对日历控件进行操作的例题，但是多少有点烦琐！

原理是一样的，地址是 http://thcjp.cnblogs.com/archive/2006/02/28/339622.html

下面是今天用#做的例题

前台HTML代码

@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<div>

控制日历的选择模式：<br />

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">

<asp:ListItem Value="None">无选择</asp:ListItem>

<asp:ListItem Value="Day">天</asp:ListItem>

<asp:ListItem Value="DayWeek">天、周</asp:ListItem>

<asp:ListItem Value="DayWeekMonth">天、周、月</asp:ListItem>

</asp:DropDownList>

<asp:Calendar ID="Calendar1" runat="server" BackColor="#FFFFCC" BorderColor="#FFCC66"

BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" Font-Size="8pt"

ForeColor="#663399" Height="200px" NextMonthText="下月" NextPrevFormat="ShortMonth"

OnSelectionChanged="Calendar1_SelectionChanged" PrevMonthText="上月" SelectMonthText="选全月"

SelectWeekText="选全周" ShowGridLines="True" Width="328px" DayHeaderStyle-Font-Italic="true" OnDayRender="Calendar1_DayRender" OnVisibleMonthChanged="Calendar1_VisibleMonthChanged">

</asp:Calendar>

<br />

<asp:Label ID="Label1" runat="server"></asp:Label><br />

选择的月是：<asp:Label ID="Label2" runat="server"></asp:Label><br />

选择的年是：<asp:Label ID="Label4" runat="server"></asp:Label><br />

<br />

显示输入的时间

<asp:DropDownList ID="ye" runat="server">

</asp:DropDownList>年<asp:DropDownList ID="mo" runat="server">

</asp:DropDownList>月<asp:DropDownList ID="da" runat="server">

</asp:DropDownList>日

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="切" Width="85px" /><br />

<br />

</div>

</form>

</body>

</html>
