DropDownList not selected in Edit page

Question

I Created Controller with "MVC 5 Controller with views, using Entity Framework" and modify "DropDownList" code in "Edit" view to

@Html.DropDownListFor(model=>model.prdepno,(SelectList)ViewBag.prdepno, new { @class = "form-control" })

in Controller use ViewBag

personal personal = db.personals.Find(id);

ViewBag.prdepno = new SelectList(db.prdeps, "prdepno", "prdepdes", emp_map.prdepno);

no error ,but dropdownlist not selected

I lookup from Adding a css class to select using @Html.DropDownList() and other question try to do that, but It not work (for me)

I don't know to do (sorry, in my communication.)

Answer 1

I think you need to change the name of ViewBag Object

personal personal = db.personals.Find(id);

ViewBag.DwPrdeps= new SelectList(db.prdeps, "prdepno", "prdepdes", emp_map.prdepno);

after that use ViewBag.DwPrdeps in your view

@Html.DropDownListFor(model=>model.prdepno,(SelectList)ViewBag.DwPrdeps, new { @class = "form-control" })
