<%# DataBinder.Eval(Container.DataItem,"xxx")%>的问题

Question

有一个函数用来打开新窗体
function open_view(nid)
        {
            alert(nid);
            window.open("News_Promulgate_View.aspx?nid="+nid","","height=300px,width=600px,left=0,top=0,resizable=yes");
        }然后在模板列里绑了一个<a><a/>:
<asp:TemplateColumn HeaderText="預覽">
                                            <HeaderStyle Width="5%" />
                                            <ItemTemplate>
                                                <a href="#" runat="Server" onclick="open_view('<%#DataBinder.Eval(Container.DataItem,"NEWS_ID") %>')">顯示</a>
                                            </ItemTemplate>
                                        </asp:TemplateColumn>
当点了“顯示”后，应该传入NEWS_ID，打开open的页面，
但点了“顯示”后网页错误，帮忙解决下吧！
