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

Question

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

@using eMCViewModels;
@model eMCViewModels.RolesViewModel
@{
    ViewBag.Title = "CreateNew";
}
<h2>
    CreateNew<
/h2>

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>RolesViewModel</legend>
        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>
        <div>
            @foreach (RoleAccessViewModel mnu in Model.RoleAccess)
            {
                 // How to use checkboxfor here?
            }
        </div>
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}
<div>
    @Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

Model.RoleAccess is a List<RoleAccessViewModel> and I want to create checkbox using @Html.CheckBoxFor() .

This is my RoleAccessViewModel

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 string IsEnabled { get; set; } // changed to bool
}

Suppose I have 5 items in list, then I need 5 checkbox with ID=menuID and Text = menuDisplayName. How can I achieve this?

EDIT

My attempt

@Html.CheckBoxFor(x=>x.RoleAccess.SingleOrDefault(r=>r.MenuID==mnu.MenuID).IsEnabled )
@Html.LabelFor(x=>x.RoleAccess.SingleOrDefault(r=>r.MenuID==mnu.MenuID ).MenuDisplayName ) 

But after changing the type of IsEnabled from string to bool . The checkbox works. But Label prints only MenuDisplayName instead of values . Can any one helps ?

Answer 1

If I undestood right, You mean this? And IsEnabled should bool type

model

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; }
}

view

@foreach (RoleAccessViewModel mnu in Model.RoleAccess)
{
    @Html.CheckBoxFor(m => mnu.IsEnabled )
}

Answer 2

Change foreach with for

@for(int i = 0; i < Model.RoleAccess.Count; i++)
{
    Html.CheckBoxFor(Model.RoleAccess[i].IsEnabled, new { id = Model.RoleAccess[i].MenuID });
    Html.DisplayFor(Model.RoleAccess[i].MenuDisplayName); // or just Model.RoleAccess[i].MenuDisplayName
}

Answer 3

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:

<div>
    @Html.EditorFor(x => x.RoleAccess)
</div>

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)

I know it is pretty old but

In your model use DataAnotations Display Attribute

public class MyModel
   int ID{get; set;};
   [Display(Name = "Last Name")]
   string LastName {get; set;};
end class
