如何将通过教师ID查询到的信息放到各个教师信息的textbox中？

Question

这个信息包括姓名，民族，学部，性别，邮箱等等~这个过程应该会用到绑定和刷新页面吧，
那个 查询栏和教师信息部分是在一个页面的
哪位能给个例子吗？

Answer 1

我是这样写的：
//page_load  这里是按教师编号查询教师信息
 string sql = "select teacher_id,teacher_name,teacher_sex,teacher_marr,"
             + "teacher_nation,teacher_type,teacher_zc,teacher_zw,"
             + "telephone,address,dept_id,dept_name,xishi_id,xishi_name"
             + "from xishi_info,dept_info,teacher_info" +
          "where teacher_id=tb1.text";
//查询button下调用数据库数据，并用databind绑定textbox
 
        SqlConnection cn = new SqlConnection("Data Source=localhost;" +
            "Integrated Security=SSPI;Initial Catslog=db_keyan");
       
        SqlCommand cm = new SqlCommand("sql", cn);
        teach_name.DataBind();
        teach_sex.DataBind();
        teach_marr.DataBind();
        tea_jg.DataBind();
        teacher_nation.DataBind();
//有两个属性是用的dropdownlist，再在其相应的函数体下写绑定语句：（这个是网上找的）
 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DropDownList dd = (DropDownList)e.Item.FindControl("DropDownListID");
            //.................
            dd.DataTextField = "name";
            dd.DataValueField = "id";
            dd.DataSource = ds;
            dd.DataBind();
        }
问题是 在最后一条里面 e.Item.ItemType中间这个Item说是System.EventArgs不包含它的定义，并且找不到可接受类型为 System.EventArgs的第一个参数的扩展方法等等。。
想问一下：
1、针对我的问题，我的思路对吗？
2、这个Item表示的是什么？
3、还有，dd.DataSource = ds;这句的ds代表的不是我调用的那个数据库的名字吗？那是什么？
刚真正接触这方面的，很多还是不懂，迷迷糊糊的
就请各位帮帮忙了~~

Answer 2

teach_name.DataBind();
  teach_sex.DataBind();
  teach_marr.DataBind();
  tea_jg.DataBind();
  teacher_nation.DataBind();这个不是这样用的。VS有自动感知功能，你这肯定是手打的或复制的。只有控件才有这种属性。顺便给你源代码，下面是后台的using System;

Answer 3

如果是GridView,则首先将GridView实例化。WEB下，将该GridView放入页面中，一般会命名GridView1，在后台中，使用实例名
GridView1.datasource = DataTable;这个DataTable表示ds中的一个表也可以是你自己构造的一个表。
GridView1.databind();综合来讲，楼主基础不足，有些基础是很难讲的，建议先找书看。
