Html CheckBoxFor helper in MVC 4 Razor - Cannot implicitly convert type 'int' to 'bool'

Question

I am trying to render list of checkboxes from an external db table BUT I keep getting this error: Cannot implicitely convert type 'int' to 'bool'.

I am guessing its not happy b/c of my strongly type view which returns a list. Can anyone please help. Thank you in advance.

my model

public partial class tblCity
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int IsSelected { get; set; }
} 

my view

@model List<Demo.Models.Sample>    

@for (int i = 0; i < Model.Count; i++)
{    
   @Html.CheckBoxFor(m => m[i].ID)  **Cannot implicitly convert type 'int' to 'bool'**
}

Answer 1

This is because you are giving it an int

@for (int i = 0; i < Model.Count; i++)
{    
   @Html.CheckBoxFor(m => m[i].ID) <- ID is an Int
}

You'd need to give it a bool. Maybe IsSelected was supposed to be a bool, and that was what you were looking for?

public partial class tblCity
{
    public int ID { get; set; }
    public string Name { get; set; }
    public bool IsSelected { get; set; }
} 

Then the view

@model List<Demo.Models.Sample>    

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