    Which part you are missing the employee.
    Are you missing in the the employee in the controller or view
    While debugging are you getting the employee from the database?
    If you are getting the employee from database there will be some issue in the JQuery ajax call or binding control.
    Can you try little bit deeper and give some information so that we can easily identify the issue.

    Hai Ahmedsa,
    There are few things which you need to remember when working with the drop-down list in MVC.
    1. Your model object should have the type of SelectList

    public SelectList Employee { get; set; }

    2. While binding in the view, you need to use the code as below:

    @Html.DropDownListFor(m=>m.SelectedEmployee , Model.Employee, "Select Employee")

    Hope it will be helpful to you.
