  1.   

    首先你要在后台代码里定义一个全局的id,每次点查询的时候把值付给这个id
    然后在后台得到这个id来查询。
    function Button1_onclick() { 
          declare sql="select * from table where id ="+<%=id%>;
          <%SqlCommand comm=new SqlCommand(sql，conn);
           SqlDataReader reader=Comm.com.ExecuteReader();
           下面要干什么我就不知道了
           %>    
    }
