;;asp+ 给我们提供了一套数据表格和数据列表的控件。这些控件可以帮助我们定制我们UI(user interFace 用户界面)而不去考
虑一种数据库或者其他的数据库。例如：在下面的例子中，我们将要介绍一下<asp:datagrid runat=server>控件是怎么样通过
sql 语句给我们提供数据的
<%@ 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
;;'以下是数据库联结
;;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>

数据表格(data grid)控件 <asp:datagrid runat=server>
给我们提供了一种非常简单的方法用传统的UI截面去显示数据查询的结果.Asp+ 的开发者现在还可以通过<asp:dataList
runat=server>
来定制数据列表显示来定制信息
<%@ 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>
