MVC Binding to checkbox

Question

I have found so many questions about this, but none of them go over or seem to go over my scenario. I have a model:

public class CheckBoxModel
{
                     


        

Answer 1

Try like this:

<%= Html.CheckBoxFor(x => x.IsSelected) %>

Also if you want to pass along the id don't forget to do so:

<%= Html.HiddenFor(x => x.Id) %>

And if you had a collection of those:

public class MyViewModel
{
    public CheckBoxModel[] CheckBoxes { get; set; }
}

you could:

<% for (var i = 0; i < Model.CheckBoxes.Length; i++) { %>
    

        <%= Html.HiddenFor(x => x.CheckBoxes[i].Id) %>
        <%= Html.CheckBoxFor(x => x.CheckBoxes[i].IsSelected) %>
    
<% } %>

which will successfully bind to:

[HttpPost]
public ActionResult MyAction(MyViewModel model) 
{
    // model.CheckBoxes will contain everything you need here
    ...
}
