Issues with selecting display row in listbox

$

Listview question...

I am making a listview box of, for example, aa, aab, ba, bb, cc.  I can populate the box with no issues (call it $listbox1)

I have a seperate textbox that accepts user input.  On any text change, I want to hightlight the item in thej list box.

$mgmtgroupsall is my listbox.
$MgmtGroupLookup is a text box
--------------
$MgmtGroupLookup_TextChanged={
    $start= [int]0
    $lookup = $([string]$mgmtgrouplookup.text)
    write-debug "Starting record $($start) with a look up of ($lookup)"

for ($ct=$start;$ct-lt$mgmtgroupsall.Items.Count; $ct++)
{
   if ($([string]$mgmtgroupsall.Items[$ct]).startswith($lookup))
    {
      # This does not work...
      $MgmtGroupsAll.SelectedItem =$ct
      write-host "Line $($ct) is what should be highlighted"
      break
    }
}

What I am missing is how to programatically set the $MgmtGroupsAll listbox to have item #3 highlighted (as if I had chosen the scroll bar to show it).

In other words, I have a list of club members (about 4000).  I want to be able to type "Smith" to then have the list box take me to the first line that starts with Smith.

I can get whatline number that line is, but where to I tell the listbox that it should be displaying item 200 (or 300, etc) in the list?
