How to use @Html.CheckBoxFor() while dealing with a List

Question

This is my View. How to use CheckboxFor():

@using eMCViewModels;
@model eMCViewModels.RolesViewModel
@{
    ViewBag.Title = \"CreateNew\";
}

CheckBoxFor works with boolean properties only. So the first thing you need to do is to modify your view model in order to include a boolean property indicating whether the record was selected:

public class RoleAccessViewModel
{
    public int RoleID { get; set; }
    public string RoleName { get; set; }
    public int MenuID { get; set; }
    public string MenuDisplayName { get; set; }
    public string MenuDiscription { get; set; }
    public bool IsEnabled { get; set; }
}

and then I would recommend replacing your foreach loop with an editor template:

    @Html.EditorFor(x => x.RoleAccess)

and finally write the corresponding editor template which will automatically be rendered for each element of the RolesAccess collection (~/Views/Shared/EditorTemplates/RoleAccessViewModel.cshtml):

@model RoleAccessViewModel
@Html.HiddenFor(x => x.RoleID)
... might want to include additional hidden fields
... for the other properties that you want to be bound back

@Html.LabelFor(x => x.IsEnabled, Model.RoleName)
@Html.CheckBoxFor(x => x.IsEnabled)
