ASP.Net MVC checkbox values from view to custom controller method

Question

I have a view with a table that displays my model items. I\'ve extracted the relevant portions of my view:

@model System.Collections.Generic.IEnumerable

You cannot use a foreach loop to generate form controls for properties in a collection. It creates duplicate name attributes (in your case name="item.IncludeProvision") which have no relationship to your model and duplicate id attributes which is invalid html. Use either a for loop (you models needs to be IList

for(int i = 0; i < Model.Count; i++)
{
  
    ....
    @Html.CheckBoxFor(m => m[i].IncludeProvision)
  
}

or create an EditorTemplate for typeof Provision. In /Views/Shared/EditorTemplates/Provision.cshtml (note the name of the template must match the name of the type)

@model Provision

  ....
  @Html.CheckBoxFor(m => m.IncludeProvision)

and in the main view (the model can be IEnumerable)

  @Html.EditorFor(m => m)
