How do you check if nothing is selected in a list?

hi im trying to make a button that deletes from a list so i use an if then else block, but i can't use listview1.selectionindex and attach it to the entire if block to do that, so what do i do?

Is list empty block

If nothing is selected, then Selection Index is zero.

So you need to pass two tests before working on the list.

Selection Index> 0

Length of list> 0

Use the green And block.
