*/列表，數據和數據棒定
asp+ 給我們提供了一套數據表格和數據列表的控件。這些控件可以幫助我們定制我們UI(user interFace 用戶界面)而不去考慮一種數據庫或者其他的數據庫。例如：在下面的例子中，我們將要介紹一下<asp:datagrid runat=server>控件是怎么樣通過sql 語句給我們提供數據的
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SQL" %>
<html>
<head>
<link rel="stylesheet"href="intro.css">
</head>
<script language="VB" runat=server>
Sub SubmitBtn_Click(Sender As Object, E As EventArgs)
Dim DS As DataSet
Dim MyConnection As SQLConnection
Dim MyCommand As SQLDataSetCommand
'以下是數據庫聯結
MyConnection = New SQLConnection("server=localhost;uid=sa;pwd=;database=pubs")
MyCommand = New SQLDataSetCommand("select * from Titles where type='" + Category.SelectedItem.Value + "'", myConnection)
DS = new DataSet()
MyCommand.FillDataSet(DS, "Titles")
MyList.DataSource = DS.Tables("Titles").DefaultView
MyList.DataBind()
End Sub
</script>
<body>
<center>
<form action="intro75.aspx" method="post" runat="server">
<asp:adrotator AdvertisementFile="ads.xml" BorderColor="black" BorderWidth=1 runat="server"/>
<h3> Name: <asp:textbox id="Name" runat="server"/>
Category: <asp:dropdownlist id="Category" runat=server>
<asp:listitem >psychology</asp:listitem>
<asp:listitem >business</asp:listitem>
<asp:listitem >popular_comp</asp:listitem>
</asp:dropdownlist>
<asp:button type=submit text="Lookup" OnClick="SubmitBtn_Click" runat="server"/>
<p>
<ASP:DataGrid id="MyList" HeaderStyle-BackColor="#aaaadd" BackColor="#ccccff" runat="server"/>
</form>
</center>
</body>
</html>

數據表格(data grid)控件 <asp:datagrid runat=server>
給我們提供了一種非常簡單的方法用傳統的UI截面去顯示數據查詢的結果.Asp+ 的開發者現在還可以通過<asp:dataList runat=server>
來定制數據列表顯示來定制信息
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SQL" %>
<html>
<head>
<link rel="stylesheet"href="intro.css">
</head>
<script language="VB" runat=server>
Sub SubmitBtn_Click(Sender As Object, E As EventArgs)
Dim DS As DataSet
Dim MyConnection As SQLConnection
Dim MyCommand As SQLDataSetCommand
MyConnection = New SQLConnection("server=localhost;uid=sa;pwd=;database=pubs")
MyCommand = New SQLDataSetCommand("select * from Titles where type='" + Category.SelectedItem.Value + "'", myConnection)
DS = new DataSet()
MyCommand.FillDataSet(DS, "Titles")
MyList.DataSource = DS.Tables("Titles").DefaultView
MyList.DataBind()
End Sub
</script>
<body>
<center>
<form action="intro8.aspx" method="post" runat="server">
<asp:adrotator AdvertisementFile="ads.xml" BorderColor="black" BorderWidth=1 runat="server"/>
<h3> Name: <asp:textbox id="Name" runat="server"/>
Category: <asp:dropdownlist id="Category" runat=server>
<asp:listitem >psychology</asp:listitem>
<asp:listitem >business</asp:listitem>
<asp:listitem >popular_comp</asp:listitem>
</asp:dropdownlist>
<asp:button type=submit text="Lookup" OnClick="SubmitBtn_Click" runat="server"/>
<p>
<asp:datalist id="MyList" repeatcolumns="2" borderwidth="0" runat="server">
<template name="itemtemplate">
<table>
<tr>
<td>
<img src='<%# DataBinder.Eval(Container.DataItem, "title_id", "/quickstart/aspplus/images/title-{0}.gif") %>'>
</td>
<td width=250 valign=top>
<b><%# DataBinder.Eval(Container.DataItem, "title") %></b>
<br><br>
Price: <%# DataBinder.Eval(Container.DataItem, "price", "${0}") %>
</td>
</tr>
</table>
</template>
</asp:datalist>
</form>
</center>
</body>
</html>
