Winforms listbox

Question

Hello,
 
I am making a program that will ask user to input date,hour,priority, description, and program displays on the list box. 
I made a list box:
(date, hour,priority, description are labels)

and I want to fill it up to something like this :

So far, got:  codes to get all the date, hour, priority, description, but only priority shows up when I do : listBox1.Items.Add(t);

Question: is there a way to "divide different categories (date, hour.. etc) within the listbox?
