dropdownlist数据绑定的问题
  protected void Page_Load(object sender, EventArgs e)
    {
        DataClassesDataContext dcdc = new DataClassesDataContext(ConfigurationManager.ConnectionStrings["db_16ConnectionString"].ConnectionString.ToString());
        var result = from r in dcdc.Leaveword
                     select new
                     {
                         id = r.id,
                         title = r.Title,

                     };
        ddl1.DataSource = result;
        ddl1.DataTextField = "title";
        ddl1.DataValueField = "id";
        ddl1.DataBind();
    }
    protected void btnChange_Click(object sender, EventArgs e)
    {
        DataClassesDataContext dcdc = new DataClassesDataContext(ConfigurationManager.ConnectionStrings["db_16ConnectionString"].ConnectionString.ToString());
        int id =Convert.ToInt32(ddl1.SelectedValue);
        Response.Write(id.ToString());
        //var result = from r in dcdc.Leaveword
        //             where r.id == id
        //             select r;
        //foreach (Leaveword lw in result)
        //{
        //    lw.Message = txtMessage.Text;
        //}
        //dcdc.SubmitChanges();
        //Response.Write("<script language=javascript>alert('修改成功！')</script>");
    }

为什么输出的总是1  难道dropdownlist值没有正确绑定吗 ？
------最佳解决方案--------------------
if(!IsPostBack)  啊
为什么PageLoad总不喜欢加这一句呢
------其他解决方案--------------------
我也有数据绑定的问题，是gridview中某列是dropdownlist，我在databind（）的时候报错，你看看能帮我解决么？
