在本级视频中,我想做两个演示,
1: 将普通控件升级为Atlas控件;
2:使用listView显示数据库数据

在本级视频中,我想做两个演示,<br />
1: 将普通控件升级为Atlas控件;<br />
2:使用listView显示数据库数据<br />
<atlas:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True">
</atlas:ScriptManager>
<br />
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>aaaaaaa</asp:ListItem>
<asp:ListItem>bbbbbbb</asp:ListItem>
<asp:ListItem>ccccccc</asp:ListItem>
<asp:ListItem>ddddddddd</asp:ListItem>
</asp:DropDownList> <br />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
<br />
我没刚才把delect的自动回传开启了的,所以页面会刷新,事实上这样做是不需要的!<br />
<br />
下面我再看演示二: 先看下效果,因为这个演示的很多都是代码,所以我预先写好了<br />
<br />
看完了,如果有什么问题请去我的博客http://www.cnblogs.com/thcjp</div>
