How do I show in a PropertyGrid properties from a list that contains a list of objects that identify the property itself?

Good morning, how can I create a property grid leaning on a vector of elements ?
Let me explain: I have a class ( MyPropertyItem ) that in my software that identifies a property. This class has 4 different properties :Name, Description , Category and Value
Other classes inherit from this class and through polymorphism override the Value property going to define the true type of the property (string , integer, datetime , …)
Using LayoutControl was simple to make sure that this allows me to change the various properties . (see attached screenshoot top )
I'd like to take advantage of PropertyGridControl to enhance the property's name , description, category but do not understand how you can do I can .
The documentation says to value the property " SelectedObject " , but my case is different . I have a list of properties List <MyPropertyItem> . If you check the list to the property " SelectedObject " rightly component automatically displays the list and detail of the view that in the "Value" property inserts the appropriate component to change. (see attached screenshoot bottom )
In summary :I have a list of items:list <MyPropertyClass>
the class contains properties that I use in propertygridcontrolName, Description , Category , Value
associating this list I get this:[ 0 ]- Name = [ Value of property]- Description = [ Value of Property]- Category = [ Value of Property]- Value = [ Value of Property][1 ]- Name = [ Value of property]- Description = [ Value of Property]- Category = [ Value of Property]- Value = [ Value of Property]… I would like to get :[ MypropertyClass [0].Name = [ Value of property MyProperty [0]. Value][ MypropertyClass . [1] Name = [ Value of property MyProperty . [1] Value]…
How can I do?
thanks
