Box Selection Lost

I am trying to set some visual feedback based on properties of selected boxes in VB.

It appears that BoxSelectionLost is fired before the selection is lost. How do I detect which box has lost selection in a loop through the selection?

e.g.
Private Sub FCX_BoxSelectionLost(ByVal box As FLOWCHARTLibCtl.IBoxItem)
dim mbox as FLOWCHARTLibCtl.IBoxItem

for each mbox in FCX.SelectedBoxes
    if not (mbox is box) then
      ...
    end if
next

This does not work. It does not equate the two boxes mbox and box. Is this because of the byVal parameter?

Basically, I need to iterate the selected boxes AFTER the box has been removed from the selection. Can you help with this please?

Thanks and regards
John

The following seems to work better:

Code
Select All
For i As Integer = 0 To FCX.SelectedBoxes.count
      mbox = FCX.SelectedBoxes.Item(i)
      If Not (mbox Is box) Then
            '...
      End If
Next i

Alternatively you can use the SelectionChanged event. It seems to fire after the selection has changed.

Regards,
Meppy
