  7. <h2>Index</h2>
  9. @using (Html.BeginForm("Index", "Employee", FormMethod.Post))
  10. {
  12. for (int i = 0; i < Model.Count; i++)
  13. {
  14. @Html.HiddenFor(m => m[i].DepartmentName)
  15. @Html.CheckBoxFor(m => m[i].IsSelected)
  16. @Html.DisplayTextFor(m => m[i].DepartmentName)
  17. <br />
