我想在table表单里面添加自定义表达式怎么弄！

Question

我在table表单里面的td里面添加<%# DataBinder.Eval(Container.DataItem,"username") %>为什么老是报错啊
<td><%# DataBinder.Eval(Container.DataItem,"username") %></td>
错误为：错误 1 “System.Web.UI.Page”不包含“DataItem”的定义，并且找不到可接受类型为“System.Web.UI.Page”的第一个参数的扩展方法“DataItem”(是否缺少 using 指令或程序集引用?) C:\Documents and Settings\Martin\My Documents\Visual Studio 2008\WebSites\WebSite2\Default.aspx 56 25 C:\...\WebSite2\
求助高手解决！

Answer 1

<%# Eval("username") %>

Answer 2

不能在table里面这么用
如果要用需要服务端控件，比如datalist，reapter，gridview等。

Answer 3

比如
<asp:DataList ID="DataList3" runat="server" RepeatColumns="1" Width="100%">
     <ItemTemplate>
                                    <table width="100%" border="0" cellspacing="0" cellpadding="1">
                                        <tr>
                                            <td width="24%" rowspan="3" valign="top">
                                              
                                                    <asp:Image ID="Image1" runat="server" ImageUrl='<%#Eval("PdtImage")%>' Width="80"
                                                        Height="80" />
                                                    <br />
                                            </td>
                                            <td  valign="top" colspan="2">
                                                <span class="t02" style="font-weight:bold">名称：<%#Eval("PdtName") %></span><br />
                                            </td>
                                        </tr>
                                        <tr>
                                            <td valign="top" colspan=3 width="60px">
                                                    套餐描述：
                                            </td>
                                        </tr>
                                            <tr>
                                           
                                            <td colspan="3" valign="top" align="left" class="t02">
                                                <%#Eval("PdtDes") %>
                                            </td>
                                        </tr>
                                    </table>
                            </ItemTemplate>
                        </asp:DataList>

Answer 4

这个table你有放在数据控件里面吗？如datalist、repeater、gridview,listview这些。
如果没放的话肯定报错了，没放的话你就在后台写html吧！

Answer 5

在datalist，reapter，gridview这个里面用，表单显示太死板了，效果不是很理想

Answer 6

也可以用这种方式
<td> <%= username %></td> 
cs文件里
protected string username;//定义并复制

Answer 7

<%# DataBinder.Eval(Container.DataItem,"username") %>  使用的范围为控件

Answer 8

asp怎么写 你就怎么写吗  以前不都是在一起写着吗
