Question

The ListViewItem.ListView property will automatically be set after being added to a owner ListView. However the ListViewItem.ListView property has no setter.

ListViewItem item = new ListViewItem(); // item.ListView == null here.
listView.Items.Add( item ); // item.ListView != null where no setter.

I’d like to know the implementation of ListViewItem.ListView get property.
What a private field is set inside the ListView.Items.Add() method? And how?
I’m trying craeting similar class relationship as a relationship between ListView and ListViewItem.

Thanks much for your help.

Answer 1

ListViewItemCollection.Add calls (indirectly) an internal method on ListViewItem:

internal void Host(ListView parent, int ID, int index)
{
    this.ID = ID;
    this.listView = parent;
    if (index != -1)
    {
        this.UpdateStateToListView(index);
    }
}

(you can see this code in a decompiler like Reflector or JustDecompile)
