How can I combine two fields in a SelectList text description?
I want put in a selected list labels the name and surname of people of an EF model. I've tried with this:
public ActionResult Insert()
{
ViewData["accountlist"] = new SelectList(time.Anagrafica_Dipendente.ToList(), "ID_Dipendente", "Surname Name", null);
Giustificativi g = new Giustificativi();
return View(g);
}
but VS returns an error, because there isn't a attribute called "surname name". how can i concat the name and surname in the selectlist label?
thanks
you could do something like this:
ViewData["accountlist"] =
new SelectList((from s in time.Anagrafica_Dipendente.ToList() select new {
ID_Dipendente=s.ID_Dipendente,
FullName = s.Surname + " " + s.Name}),
"ID_Dipendente",
"FullName",
null);
Add a new property to time.Anagrafica_Dipendente
which will represent the concatenation of the two properties:
public string Fullname
{
get
{
return string.Format("{0} {1}", Surname, Name);
}
}
and then use this:
ViewData["accountlist"] = new SelectList(
time.Anagrafica_Dipendente.ToList(),
"ID_Dipendente",
"Fullname",
null
);
Update: As of C# 6.0, the property can be more concisely written as:
public string Fullname => string.Format("{0} {1}", Surname, Name);
