MVC binding to model with list property ignores other properties

Try to change the code for the Data collection to this, and let MVC take care of the naming:

<div class="editor-field">
@for (int i = 0; i < Model.Data.Count(); i++)
{
    @Html.HiddenFor(m => m.Data[i].Id)
    @Html.HiddenFor(m => m.Data[i].ParentId)
    @Html.HiddenFor(m => m.Data[i].Name)
    @Html.TextBoxFor(m => m.Data[i].Value)
}
</div>
