Auto select listbox items from searchbox - powershell

Question

I cant seem to figure out how to auto select an item in my listbox from a searchbox.
I get a write-host back that an item is in the listbox when I use the searchbox, but I would like to autoselect the item that I search for.
The searchbox looks for the item that has the text in it from the searchbox. When you press the find button, the console says if the item is in the list or not.
I tried a couple of things with $objListbox.SelectedIndex, but I got as far as only selecting the first item in the listbox

I am not sure whether you want multiple items selected in the ListBox (depending on the SelectionMode) but you might have to deselect them first:
For ($i = 0; $i -lt $objListBox.Items.Count; $i++) {
$objListBox.SetSelected($i, $False)
}
