Listview: Position selected item at top of list

I have a textbox and a listview. When you start typing in the textbox, it searches through the listview and highlights the first item that matches.

I use .ensurevisible to make sure the item is on the screen.

This all works fine, except that the highlighted item appears at the bottom of the listview. I'd like it to automatically scroll the listview so that the matching item is the first item visible in the listview.

Any idea how to achieve this? I have tried lots of things, but nothing seems to work, so I"m happy to give maximum points to whoever can give me a solution!

try this

Private Sub txtPartNoOther_KeyUp(KeyCode As Integer, Shift As Integer)
   
    Dim X As Long
   
    If Len(txtPartNoOther) <= 1 Then
        lvwOthers.ListItems.Clear
        Exit Sub

appari,

Thanks for that. It worked, but was extremely slow (with over 1000 items in the Listview). But you pointed me in the right direction - I tweaked your code to the following:


       Set itmFound = lvwOthers.ListItems(X)
       itmFound.EnsureVisible
       itmFound.Selected = True
        Dim i As Integer
        Dim blnSelected As Boolean
        blnSelected = False
'        For i = 1 To lvwOthers.ListItems.Count
'          If lvwOthers.ListItems.Item(i).Selected Then blnSelected = True
'          If blnSelected Then
'            lvwOthers.ListItems.Item(i).EnsureVisible
'           End If
'          
'        Next i
        lvwOthers.ListItems(lvwOthers.ListItems.Count - 1).EnsureVisible
        itmFound.EnsureVisible


Thanks, and here are the points!

yeah i tested it on small set of data so it was quick:), after posting i thought of the alternative, same as yours, first make last item visible then the actual item.
