The CustomPropertyEditor QuickStart uses this pattern liberally:
{Binding Value, RelativeSource={RelativeSource AncestorType={x:Type propgrid:IPropertyDataAccessor}}, [...]}
When I try to look this interface up in the documentation or the forums, I don't see any particulars. For example:
- Which elements should I expect to implement this interface?
- What does the interface represent? Or what does it mean to add and remove properties of a parent?
Also, AddChild "gets a value indicating whether a new child can be added to an associated collection/parent." Its signature is:
void AddChild()
How is that getting anything? How would a child be added? Is this interface so internal I shouldn't even care?
