【转】ASP.NET AJAX入门系列（4）：使用ScriptManager控件实例

二．一个简单的示例

这个例子其实是UpdatePanel示例，在页面中加入了日期控件和一个下拉框，根据下拉框选择的不同，日期控件背景变为不同的颜色。示例代码如下：

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

 

<script runat="server">

    void DropDownSelection_Change(Object sender, EventArgs e)

    {

        Calendar1.DayStyle.BackColor =

            System.Drawing.Color.FromName(ColorList.SelectedItem.Value);

    }

</script>

 

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

    <title>ScriptManager Example</title>

</head>

<body>

    <form id="form1" runat="server">

        <div>

            <asp:ScriptManager ID="ScriptManager1" 

                               runat="server">

            </asp:ScriptManager>

            <asp:UpdatePanel ID="UpdatePanel1"

                             runat="server">

                <ContentTemplate>

                    <asp:Calendar ID="Calendar1" 

                                  ShowTitle="True"

                                  runat="server" />

                    <div>

                        Background:

                        <br />

                        <asp:DropDownList ID="ColorList" 

                                          AutoPostBack="True" 

                                          OnSelectedIndexChanged="DropDownSelection_Change"

                                          runat="server">

                            <asp:ListItem Selected="True" Value="White"> 

                            White </asp:ListItem>

                            <asp:ListItem Value="Silver"> 

                            Silver </asp:ListItem>

                            <asp:ListItem Value="DarkGray"> 

                            Dark Gray </asp:ListItem>

                            <asp:ListItem Value="Khaki"> 

                            Khaki </asp:ListItem>

                            <asp:ListItem Value="DarkKhaki"> D

                            ark Khaki </asp:ListItem>

                        </asp:DropDownList>

                    </div>

                </ContentTemplate>

            </asp:UpdatePanel>

            <br />

        </div>

    </form>

</body>

</html>
