I have LoginViewModel

```
        public class LoginViewModel
{
    [Required]
    [Display(Name = "Email")]
    [EmailAddress]
    public string Email { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Display(Name = "Remember me?")]
    public bool RememberMe { get; set; }

    [Required]
    [Display(Name = "Client ID")]
    public string ClientID { get; set; }
}

```

When the user logins, he enters the name of the database he will use so using the Client ID I will construct a connection string which I will use to instantiate my dbcontext EF. How do I get the values of these Client ID from another page so I can retrieve it when I instantiate my SystemContext connection string

```
    public partial class SystemContext : DbContext
{
    public SystemContext()
        : base("name=SystemContext")
    {
    }

```
