Question

dropdownlist绑定数据库？

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{

SqlConnection con = new SqlConnection("server=.;database=yangguang;uid=zxh;pwd=123456");
con.Open();
string sql = "select kindid,kindname from goodskind ";
SqlDataAdapter da = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();
da.Fill(ds, "goodskind");
con.Close();
DropDownList1.DataSource = ds.Tables["goodskind"].DefaultView;
DropDownList1.DataTextField = "kindname"; //dropdownlist的Text的字段
DropDownList1.DataValueField = "kindid";//dropdownlist的Value的字段
DropDownList1.DataBind();
}
不能绑定！为什么？？？？

Answer 1

SelectedIndexChanged是下拉框选择的时候触发的事件
你应该把数据库绑定的操作写在PAGELORD事件里

Answer 2

事件写错了 怎么在DropDownList1_SelectedIndexChanged里面绑定DropDownList1呢？
