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 ？
[最优解释]
if(!IsPostBack) 啊
为什么PageLoad总不喜欢加这一句呢

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？

  select new
                     {
                         id = r.id, 
 
                         title = r.Title,

                     };

看你的值对不对啦


int id =Convert.ToInt32(ddl1.SelectedValue);
Response.Write(id.ToString());转来转去不麻烦吗？ Response.Write(ddl1.SelectedValue);

            DropDownList5.DataSource = linq;
            DropDownList5.DataTextField = "ArticleID";
            DropDownList5.DataValueField = "ArticleID";
            DropDownList5.DataBind();
