The type System.ComponentModel.PropertyDescriptor is not marked as serializable.

[Trapulo]

I've implemented IBindingList to permit the datagrid sort rows of my
collection.
This feature is a sort of hell (MS: a simpler way, or some sample?), but now
I've done it.

My new problem is that my collection is serialized, because I pass it via
remoting from server to client. So I've this runtime error. What can I do?

thanks

Trapulo,
I would separate the presentation (PropertyDescriptor) from the domain
(serializable collection), in other words when I needed the
PropertyDescriptors I would create them. Also, seeing as they should be the
same for all instances of the collection I would make them shared variables.
Which means I would only need to create them once.

Rockford Lhotka has a complete framework described in his book "Expert
One-on-One Visual basic .NET Business Objects" that describe how to use
IBindingList and serializable collections of business objects.

Hope this helps

My problem was that I need PropertuDescriptor to implement IBindingList, so
I cannot remote it from the collectionbase object.

Ive solved marking them as nonserializable. Smart solution
