Hi, How to Add an Empty List Box and move the items from one listbox to another listbox, and save the moved data into database in asp.net MVC using EF Code first,
In my Project I have create a list box which display the data from database code is like this
In Controller:

publicActionResult Create()
        {
IEnumerable<SelectListItem> items = db.IIDBS
                .Select(c =>newSelectListItem
                {
                    Value=c.InstituteName,
                    Text=c.InstituteName
                });
ViewBag.IIDBS = items;
return View();
        }

In View:

<fieldset>
         List of Financial Institute
<%:Html.ListBox("InstituteName",(IEnumerable<SelectListItem>) ViewBag.IIDBS,"Select Financial Institute Name") %>
</fieldset>

Here I want another empty Listbox and four button which move InstituteNameof first listbox to another listboxand save those data into database.
Can anyone tell me how to do this…….
