I'm trying to create a simple scrollable list of checkboxes in ASP.NET MVC 5. I got a single checkbox to work and it correctly posts back the right value to model.Checked:
Controller
using System.Web.Mvc;
using Checkbox1.Models;
namespace Checkbox1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
var model = new TestModel
{
Checked = true
};
return View(model);
}
[HttpPost]
public ActionResult Index(TestModel model)
{
return View(model);
}
}
}
View
@model Checkbox1.Models.TestModel
@using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
@Html.CheckBoxFor(m => m.Checked, Model.Checked)
<input type="submit" value="submit" />
}
Model
namespace Checkbox1.Models
{
public class TestModel
{
public bool Checked { get; set; }
}
}
But when I try the same thing with a list of bools I can't get the bool value to pass back into the Controller. It looks like the model is getting re-instantiated and nulled out when it gets posted back to the Controller:
Controller
using System.Collections.Generic;
using System.Web.Mvc;
using Checkbox2.Models;
namespace Checkbox2.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
var model = new TestModel()
{
lstChecked = new List<bool>()
};
model.lstChecked.Add(true);
return View(model);
}
[HttpPost]
public ActionResult Index(TestModel model)
{
return View(model);
}
}
}
View
@model Checkbox2.Models.TestModel
@using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
@Html.CheckBoxFor(m => m.lstChecked[0], Model.lstChecked[0])
<input type="submit" value="submit" />
}
Model
using System.Collections.Generic;
using System.Web;
namespace Checkbox2.Models
{
public class TestModel
{
public List<bool> lstChecked;
}
}
I'd like to know why this is not working but if you could point me to a simple working example of a scrollable list of checkboxes that would also be greatly appreciated!
