I have one class that descends from Component which has few public propertis
where some of them are also objects with their own public properties.

The problem is that when I create in VS new descendand of this class and
open it in component desinger the only properties that are streamed are
those which are of simple types like String, Integer and so on. But all
object type properties that have their properties pblic are not stream
I have converter class and all attributes are set. ConvertTo method is
called for this ocnvertor calss but code for initializing these propeties is
not genrated in source code.

Any ideas what I have to do in order to make this thing to work?

Thanks in advance.

Take a look at these properties:

in the parent class:
[PersistenceMode(PersistenceMode.InnerProperty),
DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

in the embedded class:
[NotifyParentProperty(true)]

that should help you to fix your problem.

I tryed these attributes but they are ASP.NET specific which means I can't
use them in regular componenets only wiht ASP.NET which will be managed by
ASP.NET designer.

from what I see and read it looks like thi is not supported by the standard
serializer that is used to serialize componets in component desinger.

and probably in this case I will have to write my own serializer to supporte
object type properties into components.

and it is som simple to achive this in Delphi for example ;-(
all that stuff with attributes and type converters and all these special
serializers to support such simple think as property of type any object wiht
other public propeties inside it.

This is supported only for controls from what I see.
