Losing items in a ListView on clear

Visual Studio 2005
Visual Basic.net
Windows Application

I have a ListView, it is populated by a directory file list.
I change a filename, clear list, refresh and repopulate but it will not update.

My Method is the following:
User Starts program
User Selects a directory to work with
The ListView is populated with file names from the selected drirectory
The user enters search for text into a text box
The user enters replace text into a replace box
The User presses a "replace" button.
The List is updated with any changes.

Everything works except for the updating of the listview.



Form Load Code:

        MyPath = "C:\testfolder\"
        Dim dir As New DirectoryInfo(MyPath)

'Note: I have 4 listview colums set up in the design time columns collection if that makes a difference.

        ListView1.View = View.Details
        ListView1.FullRowSelect = False
        For Each file As FileInfo In dir.GetFiles()
            Dim item As New ListViewItem(file.Name)
            item.SubItems.Add(file.Name)
            item.SubItems.Add(file.LastWriteTime)
            item.SubItems.Add(file.CreationTime)
            ListView1.Items.Add(item)
        Next

Button Click:
     ListView1.clear
   ' Replace Code
   ' and other stuff here

   ' Refresh the List view with newly named files of the selected directory.
        ListView1.View = View.Details
        ListView1.FullRowSelect = False
        For Each file As FileInfo In dir.GetFiles()
            Dim item As New ListViewItem(file.Name)
            item.SubItems.Add(file.LastWriteTime)
            item.SubItems.Add(file.CreationTime)
            ListView1.Items.Add(item)
        Next

When I run the the list view is blank.
If I do not use "ListView1.Clear" I just get the same items added to the ListView
so I know the code is working, but it is the ListView.Clear that is messing things up.
I assume I have to rebuild the ListView or something?
