Collection Properties

[Norman]

Hi,
Is there any example of how to create a
collection property so it shows in the
design property windows.
E.g. I want that the user of my component
can enter strings in the collection property.
I tried:

ArrayList strArrayList = new ArrayList();
public ArrayList SetElements
{
get
{
return strArrayList;
}
set
{
strArrayList = value;
}

}
As a result the collection property shows in
the design property window but the Collection
Object Editor cannot edit any of the elements
in the strArrayList and 'set' is never invoked.

How has such a thing to be done.
I cannot find any sample code.
MS help is just very poor.

Thanks for any help!!
