update operation between two dropdownlist..........means dropdown shows the selected data when we perform update query.

Because DropDownList does not accept a list of strings. It accepts IEnumerable. Follow below links that may help you:

Hi Indu,

Try this code,

var gc = (from sub in context.Applications
where sub.Candidate_Id == Candidate_Id
select sub.appearing_class).toList();

ViewBag.appearing_class = new SelectList(gc,context.Applications.appearing_class,context.Applications.appearing_class,0);

public ActionResult EditData(int Candidate_Id=0)
{
Application model = context.Applications.Find(Candidate_Id);
var x = (from c in context.Applications where c.Candidate_Id == Candidate_Id select c).FirstOrDefault();
string gc = (from sub in context.Applications
where sub.Candidate_Id == Candidate_Id
select sub.appearing_class).First();
ViewBag.appearing_class = new SelectList(gc);
model.Candidate_Id = x.Candidate_Id;
return View(model);
}

VIEW :
