Using CheckBoxFor

Question

I have a class role as follows:

public enum Role
{                                            
    User1 = 1,
    User2 = 2,
    User3 = 3, 
    User4 = 4
}

I have the following codes in my model

public Role[] UserRoles { get; set; }
 User user = User.Load(1);
        UserRoles = user.Roles;

My question is this: I want to check the box for each role, and if Role == userRoles, the checkbox is true else false. How can I use @ HTml.CheckboxFor ... Can I get an example.

Answer 1

You are going to peel off with hard-coded values ​​if you are trying to create a list of flags based on data from the database.

You can try something like my CheckBoxListFor <> extension:

Answer 2

to use CheckBoxFor you need a ViewModel with bool properties

public class YourVM
{                                            
  public bool[] Roles {get;set;}
}

and in view

@model YourVM

@for (int i = 0; i < Model.Roles.Count(); i++) {
@Html.CheckBoxFor(m => m.Roles[i])
}
