I have this class:

Code:
class Toy : ListViewItem
{
//costum attributes

//constructor (this has to be like this so it can deserialize)
public Toy(SerializationInfo info, StreamingContext context) : base(info, context)
{
}

}
but then when I deserialize all my costum attributes are lost... What I'm I doing wrong?
Thank you very much (sorry for making so many questions o this foruns xD)
