Solution 3

C#

DataTable table = new DataTable();
           cmd = new SqlCommand();
           cmd.CommandText = "GetEmployee";
           cmd.CommandType = CommandType.StoredProcedure;

           table = dbConn.ExecuteQuery(cmd);
           ddlEmp.DataSource = table;
           ddlEmp.DataValueField = "DeptId";
           ddlEmp.DataTextField = "DeptName";
           ddlEmp.DataBind();
