This is my DocumentController and its actions. You can find list for showing, submit, and also details, delete.

namespace PMPDI_APP.Controllers
{
    public class DocumentController : Controller
    {
        PMPDIEntities db = new PMPDIEntities();

        // CreateList
        public ActionResult List(string document)
        {
            var docum = db.Documents.Include(p => p.Project);
            var a = from p in db.Documents.Include(p => p.Project)
                    select p;

            if (!String.IsNullOrEmpty(document))
            {

                a = a.Where(
                c => c.FileDName.Contains(document)
                || c.Project.nameProject.Contains(document)
                 || c.TypeDocument.typeDocumentName.Contains(document)

                );
            }
            return View(a.ToList());
        }
        // CreateInsert

        public ActionResult submit()
        {
            ViewBag.ProjectID = new SelectList(db.Projects, "ProjectID", "nameProject");
            ViewBag.typeDocumentID = new SelectList(db.TypeDocuments, "typeDocumentID", "typeDocumentName");
            return View();
        }
