How to set group headers in listview not selectable?

I need some help for my listview element, I want to use listview with groups. But i want to make the group headers not selectable, i want to use them as a separator?

How can I do this?

I've added this.lstView.SelectedIndexChanged event listener. Also I have two groups where I need every index from each item. If I debug the index with ((ListViewItem)lstView.SelectedItems[0]).Index in the event listener I get an exception if the group header is selected, so I want to disable the selecting of 开发者_如何学编程group headers.

// Adds a new group that has a left-aligned header
listView1.Groups.Add(new ListViewGroup("List item text", HorizontalAlignment.Left));
