Comments

The Expandable property defines whether the item is expandable.

Normally, only a parent item (with dependents) is expandable. An expandable item displays an expand/collapse button and other attributes, such as the Items.ItemImageExpandable graphic.

A leaf item can be made a "temporary" parent item by setting the item's Expandable property to True. The item now displays an expand/collapse button and other attributes, such as the Items.ItemImageExpandable graphic. The item can now also generate an ItemClick event to expand the item. The application can then add child items as the user expands this "temporary" parent item, making it into a real parent item.

When setting the Expandable property, an item's dependents are always removed, unless the item is already expanded.

If an item's Expandable property is set to False, the item is collapsed (and its dependents are removed).

If an item is already expanded or has dependents when setting Expandable to True, the item remains unchanged. It is not expanded.
