Drag and Drop From ListView to ListBox

I am using TreeView to display files in ListView  which works fine. I am trying to drag a file from the ListView to a ListBox to do things with the file but I cannot make it work. I do have Allow Drop set to True in the ListBox. Below is the code I have so far.

For the ListView
Private Sub lstDirectoryInfo_ItemDrag(sender As Object, e As ItemDragEventArgs) Handles lstDirectoryInfo.ItemDrag
        Dim lvItem As ListViewItem
        lvItem = CType(e.Item, ListViewItem)
        Dim importantData As String
        importantData = lvItem.Text
        Dim drp As DragDropEffects
        drp = lstDirectoryInfo.DoDragDrop(e.Item, DragDropEffects.Copy)
        MessageBox.Show(drp.ToString())
    End Sub

For The ListBox
Private Sub lstSFTP_DragDrop(sender As Object, e As DragEventArgs) Handles lstSFTP.DragDrop
        Dim str As String = CStr(e.Data.GetData(DataFormats.StringFormat))
        lstSFTP.Items.Add(str)
    End Sub
    Private Sub lstSFTP_DragEnter(sender As Object, e As DragEventArgs) Handles lstSFTP.DragEnter
        If (e.Data.GetDataPresent(DataFormats.FileDrop)) Then
            e.Effect = DragDropEffects.Copy
        Else
            e.Effect = DragDropEffects.None
        End If
    End Sub

What I want to accomplish is have the filename in the ListBox.

Thank You
