SYMPTOMS

A CurrencyManager object is bound to a parent table and some child tables in a Windows Forms application that was built by using the Microsoft .NET Framework 2.0. When you delete the last row from one of these tables, the CurrencyManager object triggers additional instances of the following events:
  • The CurrentChanged event
  • The CurrentItemChanged event
  • The PositionChanged event
Therefore, the applications that handle these events perform very slowly.
