SelectList ToShortDateString视图包

Question

My project is MVC5, using EF 6.1; I generate dropdownlist using the following:

Model:

public partial class LogBook
{
    public string ID { get; set; }
    public string TheName { get; set; }
    public System.DateTime Day { get; set; }
}

Controller:

var list = db.LogBook.Where(i => i.TheName == xxx).OrderByDescending(x => x.Day).ToList();
ViewBag.Logbooks = new SelectList(list, "ID", "Day");

View:

@Html.DropDownList("logbookdate", ViewBag.LogBooks  as SelectList) 

The result shows:

11/11/2014 12:00 AM

How can I just display the date?

Answer 1

Try this:

var list = db.LogBook.Where(i => i.TheName == xxx).Select(d=> new {ID= d.TheName, Day = d.Day.ToShortDateString()).OrderByDescending(x => x.Day).ToList();
 ViewBag.Logbooks = new SelectList(list, "ID", "Day");

Haven't done practical but should work.

Edit:

IEnumerable<SelectListItem> selectList = 
    from c in db.LogBook
    where c.TheName equals xxx
    select new SelectListItem
    {
        Text = c.ID,
        Value = c.Day.ToShortDateString()
    };

Then bind it to dropdonwlist on front.

You can give it a try. I have not checked syntax. Hope its fine.

Try this:

var list = db.LogBook.Where(i => i.TheName == xxx).OrderByDescending(x => x.Day).ToList();

Change in query

IEnumerable<SelectListItem> selectList = db.LogBook
                                           .Where(i => i.TheName == xxx)
                                           .Select(c => new SelectListItem
                                           {
                                              Text = c.ID,
                                              Value = c.Day.ToShortDateString()                                                
                                           });
