解决方案 »

  1.   

    可以在点击gridview的按钮时获取本行的ID  存放到对象 然后层从对象取值
      

  2.

            }
            protected void lbToWho_DataBinding(object sender, EventArgs e)
            {        }    }
    }
      

  3.   

    在gridview中添加一个隐藏列  存放ID  这个没问题吧？  
    这样就可以在单击的时候获取这个ID  也没问题吧？
    然后就不会获取ID是嘛？
      

  4.   

    在你要弹出层中方一个隐藏HiddenField控件 如:ID="hdfID"
    function showFloat(id)
    {   
    //先清空这个控件的值//再将参数赋值
     document.getElementById("hdfID").InnerText=id;
    //
    .......
    }
    在后台获取这个控件的值<asp:CommandField HeaderText="编辑" ShowEditButton="True" 
                        EditText='&lt;a href="javascript:void(0)" onclick="showFloat(<%#Eval('ID')%)"&gt;编辑&lt;/a&gt;' />
      

  5.   

    在td 的 行里面 给一个 click事件把ID作为参数传过去
