新闻发布系统的修改、添加、删除页面。。
请大侠赐教。。按添加之后，还是出现更新的页面。。
还有更新出现SQL不支持date数据其中有错误说。。  <asp:TextBox ID="TextBox1" runat="server" Text='<%# Now() %>'></asp:TextBox>
这个Now是不是有问题。。他说上下文中不存在名称。。不过，书上是这么写的。。菜鸟求大侠指教！！

解决方案 »

  1.   

    你这个Now在哪里？cs页面中应该存在一个最少为protected的Now()函数protected string Now()
    {
     return "content that you want to be displayed!";
    }
      

  2.   

    Now函数是否存在
    很少这样写
      

  3.   

    protected string Now()
    {
     return DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
    }
      

  4.   

    在pageload里面写 
    TextBox1.text =  DateTime.Now.ToString();或者写个方法 前台调用
     public string Now()
            {
                return DateTime.Now.ToString();
            }
    //前台 <asp:TextBox ID="TextBox1" runat="server" Text=' <%= Now() %>'> </asp:TextBox>
