Я пытаюсь связать данные со значениями в раскрывающемся списке из базы данных SQL.Я получаю сообщение об ошибке: DataBinding: «System.Data.Common.DataRecordInternal» не содержит свойство с именем «EmpName_vc».Я не могу понять, в чем именно проблема.Я хочу привязать данные к раскрывающемуся списку на основе пройденного запроса sql.

cmd.Parameters.AddWithValue("@intDeptId", LocId.Text);

Cnn.Open();
using (SqlDataReader dr = cmd.ExecuteReader())
