ListViewGroupCollection

[NewsBot]

Hello!

 

I've been looking into the ListView control and there is one thing I hope someone here can answer.

 

Every instance of a ListView has a Groups property which returns a ListViewGroupCollection. It is not explicitly possible to instantiate a ListViewGroupCollection, I get the following error:

"Error*1*The type 'System.Windows.Forms.ListViewGroupCollection' has no constructors defined [...]"

But obviously has the ListView class instatiated one instance of ListViewGroupCollection; how has that been done? Some kind of friend class?

 

Another question is regarding when adding ListViewItems to a group's Items property (theListView.Groups[0].Items.Add(...)). How does "theListView" know when an item is added to the collection of items, so that it can add it to the control? Does "theListView" listen to events that*ListViewItemCollection triggers when adding, removing..? Or does the collection have a reference to "theListView"..?

 

Thanks in advance
