Hi,
I am making an vb.net 2010 application for a depot.
The user can put what comes in and goes out the depot.
Then you can see a listview with all the incoming and outgoing.
What you see is this as an example.

Item Amount In/Out

Apple 10 in
Apple 5 out
Apple 3 in
Shoes 90 in
Shoes 5 out
Pants 23 in
Pants 44 in
Pants 9 out

Now I want to push a button to show me only this in the same listview

Item Amount

Apple 8
Shoes 85
Pants 56

of-course the listview is never a fixed amount of items.

Thanks for the help
