Question

if I’m using a ListBox for data binding, the listbox generates a listboxitem for each item, same goes for combo box and comboBoxItem.
My question is – how do i set it myself for a given ItemsControl? (e.g. make the containing element be Border)?

After digging a little with ILSpy –

Apparently The magic is done in

    protected override DependencyObject GetContainerForItemOverride()
    {
        return new ListBoxItem();
    }

This is where ListBox does it – and in my control I should override this as well.
