Can a custom web component be serialized? And how can the component be
serialized to xml?

Hi

Based on my understanding, you want to serialize the properties of your
custom control.
Normally, custom control is also a class, so you can just do like normal
serialization. Your custom control should implement the ISerializable
interface.
To serialize to xml or binary, this is determined by the Formatter ,
BinaryFormatter for binary serialization, SoapFormatter for xml
serialization.

For more information about serialization, please refer to Jeffrey Richter's
