Let's say I want to create detached entity instance with properties matching existing entity. Classic example - in data entry details I want to create copy of the order line.
 
How do I do this? Currently I'm manually copying each property value. Is there anything built-in for this?

Yes, all DevForce entities implement ICloneable via an explicit interface implementation.   You can cast to ICloneable and call Clone:
  Customer customerCopy = ((ICloneable)aCustomer).Clone() as Customer;
 
The returned entity is in a Detached entity state.
 
More information on working with entities is in the DevForce Resource Center - http://drc.ideablade.com/xwiki/bin/view/Documentation/create-modify-delete.

Thank you for reply!
 
I tried to do it with ICloneable but it won't work. Is it SIlverlight issue?
I get error Error 6 'System.ICloneable' is inaccessible due to its protection level

Oh sorry, yes, System.ICloneable is a .NET only interface.   In SL applications you can use IdeaBlade.Core.ICloneable.
