You have to use <Serializable()> attribute prefixed to the
class declaration before you keep object of this class in
viewstate. However, larger the object, slower will be
performance. There will be risk of viewstate getting
corrupted.

Eg
'' in class definiton:
<serializable()> Public Class Fruit
private sName as string
public sub new(ByVal Name as string)
sName = Name
End Sub
readonly property Name as string
Get
return sName
end get
End Class

''in code behind:
if page.ispostback = false
dim MyApple as new Fruit("Kashmiri Apple")
ViewState("oMyFruit") = MyApple
end if

'' In button click
label1.text = ctype( ViewState("oMyFruit") , Fruit).Name
