SqlConnection con=operate.createConnection();
con.Open();
SqlCommand cmd=new SqlCommand("select * from province",con);
SqlDataReader sdr=cmd.ExecuteReader();
this.ddlProvince.DataSource=sdr;
this.ddlProvince.DataTextField="proName";
this.ddlProvince.DataValueField="proID";
this.ddlProvince.DataBind();
sdr.Close();
con.Close();
}
{
SqlConnection con=operate.createConnection();
con.Open();
SqlCommand cmd=new SqlCommand("select * from province",con);
SqlDataReader sdr=cmd.ExecuteReader();
this.ddlProvince.DataSource=sdr;
this.ddlProvince.DataTextField="proName";
this.ddlProvince.DataValueField="proID";
this.ddlProvince.DataBind();
sdr.Close();
con.Close();
}
