i want to add Mem_NA to dropdownlist, Viewbag contains all the user details. Problem is in View page. An error shows in model.Mem_Na. Please help me to solve this.

Answer 1

Please, change your code

from

@model IEnumerable<....Members.Models.MemberBasicData>
@Html.DropDownListFor(model => model.Mem_Na, (SelectList)ViewBag.Users, "--Select Users--")

to

@model ....Members.Models.MemberBasicData
@Html.DropDownListFor(model => model.Id,new SelectList(ViewBag.Users,"Id","Mem_NA"), "--Select Users--")

It works for me everytime

Answer 2

Your model is an IEnumerable of MemberBasicData, not an instance of MemberBasicData. This means you cannot access properties of MemberBasicData directly, as the property doesn't exist against an IEnumerable.

From what little I can see from your code I imagine you want your model to be an instance, not a list.
