I tired your suggestion above. However, I get a "The display column 'StartDateSort' specified for the table 'Visits' does not exist." at run time. Below is my data annotation code. I kept it simple for testing. I will go back and add more fields once
I get it working:
namespace Admiral_CGDoorsModel
{
[MetadataType(typeof(VisitMetaData))]
[ScaffoldTable(true)]
[DisplayColumn("StartDateSort")]
[DisplayName("Visits")]
public partial class Visit
{
public string StartDateSort
{
get{return StartDate; }
}
public Visit()
{
RecordID = Guid.NewGuid();
}
public partial class VisitMetaData
{
[ScaffoldColumn(false)]
[Display(Name = "RecordID",Order = 10)]
public Object RecordID { get; set; }
[ScaffoldColumn(false)]
[Display(Name = "ShipID",Order = 20)]
public Object ShipID { get; set; }
[ScaffoldColumn(true)]
[Display(Name = "End Date",Order = 30)]
public Object EndDate { get; set; }
[ScaffoldColumn(true)]
[Display(Name = "Start Date",Order = 40)]
public Object StartDate { get; set; }
}
}
}
Hi SonnyTate, EF does not support custom properties and as such DD does not see them if this is a serious requirement use Computed Column in the DB or Switch to Linq to SQL

I guess I could have asked my question better. All I am trying to is to have a dropdown filter display a list of ships and start dates from my Visits table. This table has ShipName and StartDate fields. I would like dropdown to display ShipName ASC and StartDate
DESC, like this:
HMS Britannic, 1942-08-03
HMS Britannic, 1932-02-23
HMS Queen Elizabeth, 1967-07-14
HMS Queen Elizabeth, 1965-02-18
HMS Titanic, 1913-11-03
HMS Titanic, 1911-05-22
This is the code I have so far:
namespace Admiral_NSSAModel
{
[MetadataType(typeof(VisitMetaData))]
[ScaffoldTable(true)]
[DisplayColumn("ShipName", "ShipName")]
[DisplayName("Visits")]
public partial class Visit
{
public override string ToString()
{
return ShipName.ToString() + " " + string.Format("{0:yyyy-MM-dd}", StartDate);
}
public Visit()
{
VisitID = Guid.NewGuid();
}
public partial class VisitMetaData
{
[ScaffoldColumn(true)]
public Object ShipName { get; set; }
[ScaffoldColumn(true)]
[DataType(DataType.Date)]
public Object StartDate { get; set; }
}
}
}
While this works, it only sorts by ship. Is there any way I can do it by ShipName ASC StartDate DESC?

Hi Sony, I the only way I can think of doing this would be to create you own custom field template based on the ForeignKey field template.
