CS C# templates: Why are DateTime properties ReadOnly?

Skafa posted on Sunday, October 01, 2006

I noticed that DateTime properties are generated with only a set {} accessor. Why is that?

Specifically, which templates are you referring to?

Remco,

The DateTime properties are intended to be used for sorting when bind into control such as datagrid.  The set accessor is available through string properties.  Through this property, you can assign empty date.

I needed to databind to the DateTime property. (not to the ..String property)

So i created the set accesor, which sets _smartDateProperty.Date to value. Does this cause any unexpected behaviour? It seems to work though.

You should be able to bind to a Smartdate with no problems -- this is a common requirement.

RJ,

Since SmartDate is now a value type (struct), it should be safe to expose a property as SmartDate.  In Csla 1.x, you'll run into problem where user can do SmartdateProperty.Date = newDateValue and avoid the code inside the set accessor.

However, I don't know how well third party control dealing with SmartDate.  I think a good one will work just fine.

If the property does not allow empty date value, then adding set accessor would work just fine.

But then if you don't allow empty date, you should just use DateTime instead of SmartDate.
