To get the value of check boxes from a list of dynamicallly created check boxes in razor view engine - asp.net-mvc-3

Question

How to find the values of checkboxes(i.e., whether checked or not) from a list of dynamically created check boxes in razor view engine? the code runs as follows...
#foreach (var item in Model))
{
<tr>
<td class="Viewtd">
#Html.ActionLink(item.Title, "Edit", new { id = item.id})
</td>
<td>
#Html.CheckBox("ChkBox"+item.ThresholdID , false, new { id = item.id})
</td>
</tr>
}
How to get those check boxes values in the controller?

Answer 1

Do it the proper way: using view models and editor templates.
As always start by defining a view model:
public class MyViewModel
{
public string Title { get; set; }
public string Id { get; set; }
public bool IsThreshold { get; set; }
}
then a controller to populate this view model :
public class HomeController : Controller
{
public ActionResult Index()
{
var model = new[]
{
new MyViewModel
{
Id = "1",
Title = "title 1",
IsThreshold = false,
},
new MyViewModel
{
Id = "2",
Title = "title 2",
IsThreshold = true,
},
new MyViewModel
{
Id = "3",
Title = "title 3",
IsThreshold = false,
},
};
return View(model);
}
[HttpPost]
public ActionResult Edit(MyViewModel model)
{
// This action will be responsible for editing a single row
// it will be passed the id of the model and the value of the checkbox
// So here you can process them and return some view
return Content("thanks for updating", "text/plain");
}
}
and then the Index view (~/Views/Home/Index.cshtml):
#model IEnumerable<MyViewModel>
<table>
<thead>
<tr>
<th></th>
<th>Threshold</th>
</tr>
</thead>
<tbody>
#Html.EditorForModel()
</tbody>
</table>
and finally the editor template (~/Views/Home/EditorTemplates/MyViewModel.cshtml):
#model MyViewModel
#{
ViewData.TemplateInfo.HtmlFieldPrefix = "";
}
<tr>
#using (Html.BeginForm("Edit", "Home"))
{
#Html.HiddenFor(x => x.Id)
#Html.HiddenFor(x => x.Title)
<td><input type="submit" value="#Model.Title" /></td>
<td>#Html.CheckBoxFor(x => x.IsThreshold)</td>
}
</tr>
