View State Serialization problem

Karahan Celikel · Aug 22, 2003

I have a custom collection class subclassing the CollectionBase. Even if it
is marked as [Serializable] it gives an error when I try to store it in
viewstate. Following is the error message and stack trace info.

Error:
The type 'InTouch.Wip.Web.Admin.Content.WrappedContentCollection' must be
marked as Serializable or have a TypeConverter other than ReferenceConverter
to be put in viewstate

Stack:
HttpException (0x80004005): The type
'InTouch.Wip.Web.Admin.Content.WrappedContentCollection' must be marked as
Serializable or have a TypeConverter other than ReferenceConverter to be put
in viewstate.]

Hello Karahan,

Thanks for posting in the group.

Under this situation, the framework don't know the complex object's state
management requirements and so can't provide the management automatically
by creating TypeConverter. You have to deal with IStateManager interface as
it provides the link for state management for complex objects. This has
also the benefit that you can optimize the state management so that no more
than everything absolutely required is stored to ViewState (to make less
overhead).

For your questions, I think you need to implement IStateManager on my
collection and a type converter on my collection item.

Hope that helps.
