I try many coding, but not work, because i have no more knowledge about this.
And search on google but many example are on Datagridview, but I used Listview
please help me sir.......

Fiestly please show the code what you did.

Secondly, for every catagory at the end the subtotals should be added as a listitem for that catagory. Or you have to create an User Control for your use.
