How to speed up TreeView Clear method

by  SBendBuckeye  Posted    (Edited  )

Ensure SelectedNode is nothing before calling Clear method.
Code: 
Public Shared Sub SmartClearNodes(ByVal t As TreeView)
  t.BeginUpdate()
  Try [b]
    t.SelectedNode = Nothing [/b] ' this is it ;-)
    t.Nodes.Clear()
  Finally
    t.EndUpdate()
  End Try
End Sub
