Databound ListBox Won't Update on Clear?

[VagabondSW]

I have a ListBox control bound to an ArrayList:

 

  Dim m_expressionFilters As ArrayList
 Dim m_expressionBindingManager As BindingManagerBase
 m_expressionFilters = New ArrayList
 m_expressionBindingManager = BindingContext(m_expressionFilters)
 lstboxFilters.DataSource = m_expressionFilters

When I add an Item to the ArrayList, that change is immediately reflected in

the ListBox:

 

  m_expressionBindingManager.SuspendBinding()
 m_expressionFilters.Add(CurrentFilter)
 m_expressionBindingManager.ResumeBinding()

However, when I call the Clear method of the ArrayList, the changes are not

reflected in the ListBox:

 

  m_expressionBindingManager.SuspendBinding()
 m_expressionFilters.Clear()
 m_expressionBindingManager.ResumeBinding()

At this point, the m_expressionFilters ArrayList has a Count of zero, but

the Items formerly held in the ArrayList are still listed on the form in the

ListBox. I have tried calling the Refresh and Update methods on the

ListBox, but that produced no visible changes at all.

 

Any help or advice would be greatly appreciated.
