  //SysAssessmentSubAreaCategory is enity model class
  public List<SysAssessmentSubAreaCategory> ListSysAssessmentSubAreaCategory;   
}

            { 
              var model = new AssessmentAreaContent();
                model.ListSysAssessmentSubAreaCategory = db.SysAssessmentSubAreaCategory.Where(c => c.AssessmentAreaId == id).ToList();
                return View(model);
            }

Controller Http Post Method

 [HttpPost]
        public ActionResult AssessmentArea(Web.Models.AssessmentAreaContent assessmentAreaContent)
        {

            //assessmentAreaContent.ListSysAssessmentSubAreaCategory is null here ?? ; 
            return RedirectToAction("AssessmentArea", "AssessmentArea");
        }

@{
    ViewBag.Title = "Area";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@using (Html.BeginForm())
{
    @{ 

    if (Model != null)
                        {
       foreach (var category in Model.ListSysAssessmentSubAreaCategory)
                            {           


              <strong>@Html.EditorFor(item => category.AreaCategoryName)</strong>  
                <br />
       }

make an editor template with the name SysAssessmentSubAreaCategory. note that name of template is same as type of your list objects. in this template write something like

@model Web.Models.SysAssessmentSubAreaCategory
<strong>@Html.EditorFor(item => category.AreaCategoryName)</strong>  
                <br />

in your main view just make these changes

if (Model != null)
                        {
       Html.EditorFor(x=>x.ListSysAssessmentSubAreaCategory)
       }

leave the rest unchanged. fill out the form and post it and you will have values in the controller.

There is no input holding values for ListSysAssessmentSubAreaCategory so that in post back you have that property filled.

You need that values to be saved server side (e.g. in session ) or be represented in input form.
