Extending ListView class

Question

I want to have a ListView that in addition to "item.Text" and "item.Name" should have some more custom properties for each ListViewItem.

How can I do that (syntax and etc...)

Also is it possible to set a List<string> or List<class> as a property of an listview item?

Thanks.

Avoid using a control as a collection class. Separate the data from the view. — Hans Passant

You can inherit from ListViewItem class.

public class MyListViewItem : ListViewItem {
    public List<object> Tags {get; set;}
}

// ... elsewhere

var item = new MyListViewItem {
    Text = "Hello world!",
    Tags = new List<object> { null, true, 15, "asdf", 78.7 }
};
this.listView1.Items.Add(item);

hmm, I was thinking of the whole ListView class, not the item only. will this do the same thing? I want all the items have same proprety attributes.

The ListViewItem is another class than ListView. You can not "add property" to every item in listview. The every item can be instance of different class derived from ListView.
