Am clase de Companie, Țară și Stat. Statul este legat de Țară Statul și Țara sunt cheia străină pentru companie
Problema Vizualizarea companiei afișează atât statul, cât și țara ca meniuri derulante separate. Dar mă aștept, când selectez Stat, Țara corespunzătoare să se schimbe sau invers. Este posibil acest lucru în modelul MVC5 EF.
Clasa companiei
public class Company
{
public int CompanyID { get; set; }
[Required]
[StringLength(100,MinimumLength=3)]
public string Name { get; set; }
[StringLength(200)]
public string Address { get; set; }
public int? StateID { get; set; }
public virtual State State { get; set; }
public int? CountryID { get; set;}
public virtual Country Country { get; set; }
public int CompanyTypeID { get; set; }
public virtual CompanyType CompanyType { get; set; }
}
Clasa de țară
public class Country
{
public int CountryID { get; set; }
[Required]
[StringLength(100)]
public string Name { get; set; }
public virtual ICollection<State> States { get; set; }
public virtual ICollection<Company> Companies { get; set; }
}
Clasa de stat
public class State
{
public int StateID { get; set; }
[Required]
[StringLength(100)]
public string Name { get; set; }
public int CountryID { get; set; }
public virtual Country Country { get; set; }
public virtual ICollection<Company> Companies { get; set; }
}
Am schelă și am generat vizualizarea și vizualizarea companiei pentru referință
