Dropdownlist in MVC 4 - asp.net-mvc

Question

I am trying to use simple dropdownlist in my edit form, where user can correct information, with help of dropdownlist.
So I use this:
public ActionResult Edit(string zonesList)
{
using (var dbVn = new userDbEntities())
{
...
var zList = new List<string>();
var zQuery = from d in dbVn.TimeZoneTables // take data for List from table
select d.TimeZone;
zoneList.AddRange(zQuery.Distinct());
ViewBag.zonesList = new SelectList(zList);
}
}
And in View I put this code:
Zones: #Html.DropDownList("zonesList")
My question is, how in View use this:
#Html.DropDownList("zonesList")
on this code
#Html.EditorFor(model => model.TimeZoneId)
Thanks for any idea.

Answer 1

Use jquery or javascript as below:
#Html.DropDownList("zonelist", new SelectList(ViewBag.zonesList,<value>,<text>),"Select Vendor/customer",new{ #class = "form-control",required = "required",#id="zone" })
Now want to change editor for value
#Html.EditorFor(model=>model.TimezoneId,new{#id="time"})
Jquery code for above
<script type="text/JavaScript">
$(document).ready(function () {
$("#zone").change(function(){
var t =$("#zone").val();
if(t==/*somevalue*/)
{
//set value for time id
//like $("#time").val(/*new val*/)
}
});
});
</script>

As I am using Time Zones I find cool solution that works only for time zones. First I actualy don't need table with time zones saved, but simple in my View I call library of .Net timezones:
#Html.DropDownListFor(o =>o.TimeZoneId, TimeZoneInfo.GetSystemTimeZones().Select(o => new SelectListItem{Text = o.DisplayName, Value = o.Id}))
