How can I get a Click event in a ListBoxItem?

Question

Is there any way to implement Clickon ListBoxItem? Exists MouseLeftButtonUp, but it’s actually not the same, I can pull it to another place and drag it to another ListBoxItem, and it still works, a little tho problem, maybe this is strange for tho users

Answer 1

Can you create a new ControlTemplate for ListBoxItem with something clickable as the root element (like Button), handle the click-event event and place the ContentPresenter inside the "clickable"?
