How do I put the items I picked in listview to my database? - vb.net

Question

See pic
Just new to vb.net. Anyway, I don't know how I will put the value of product and price I picked in the database since it's in the list view. I tried
Dim txtValue as String
txtValue = ListView1.FocusedItem.SubItems(0).text. To get the values of the columns.
In the picture I provided, If I the put the customername and I pick her order in the listview1 it will save in my database. And it will show it my listview2. Just disregard the address.
UPDATE I think this code works but there's still error message showing up.Error message see pic

Answer 1

Try this
txtValue = ListView1.SelectedItems(0).SubItems(1).Text
txtValue1 = ListView1.SelectedItems(0).SubItems(2).Text
To get the Product and price from the list view
I assume you have the MultiSelect set to false.
