This is entirely dependant upon the intended lifetime of the component.
1. if it lives within a single method call. No Owner, free it yourself using
a finally block.
2. if the lifetime exactly follows the parent then owner=parent.
3. if its lifetime follows that of an object not it's parent and that object is
not responsible for the release of your parent then Owner = object.
Owner = form is a simple model to simplify the streaming process. Objects
should be quite capable of having Owner=parent unless the object is supposed
to be released before or after the parent.
My guidelines are:
- The only excuses for consuming memory are UI response and performance.
- Release as soon as possbile - memory is valuable.
- Some components are expensive to recreate regularly, instance pooling
may speed things up - Lifetimes are managed by the instance pool.
