Inherit from ParentAdapter to specify a parent-child relationship in the WPF Designer.
It is frequently the case in Windows Presentation Foundation (WPF) that moving an element from one child to another or adding an element to a parent requires specialized knowledge of the parent-child relationship. Rather than implementing container-specific logic for each container, the ParentAdapter class defines an extensibility point and supports a generic mechanism for changing the parent of one object into another.
A ParentAdapter is invoked by the Parent method. The ModelParent locates a ParentAdapter for current and proposed parent objects. If no ParentAdapter exists, an object cannot be assigned a parent.
The ParentAdapter class enables containers to perform logic when a parent is removed. For example, if an object is being moved from a Canvas to a Grid, the canvas’s attached properties can be removed automatically.
