Say I have an enum something like:
enum OrderStatus
{
AwaitingAuthorization,
InProduction,
AwaitingDespatch
}
I've also created an extension method on my enum to tidy up the displayed values in the UI, so I have something like:
public static string ToDisplayString(this OrderStatus status)
{
switch (status)
{
case Status.AwaitingAuthorization:
return "Awaiting Authorization";
case Status.InProduction:
return "Item in Production";
... etc
}
}
Inspired by the excellent post here, I want to bind my enums to a SelectList
with an extension method:
public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
however, to use the DisplayString values in the UI drop down I'd need to add a constraint along the lines of
: where TEnum has extension ToDisplayString
Obviously none of this is going to work at all with the current approach, unless there's some clever trick I don't know about.
Does anyone have any ideas about how I might be able to implement something like this?
