In a DataGridView, I allow the user to change a cell, which fires the
CellValueChanged event (which I use to validate the cell contents),
followed by the EndCellEdit event, which I use to doctor the entry
(eg, change to upcase, etc).  The problem is that when I doctor the
cell contents, the CellValueChanged event is fired a second time.

I want to do the following:

In CellClick ...
[Turn off the CellValueChanged event]
BeginEdit (true);

In EndCellEdit ...
[Turn on the CellValueChanged event]
doctor the contents

The question is, how do I turn off an event.  I can think of two ways;

1.  Use a flag.
2.  m_Event = new DataGridViewCellEventHandler (ProcName);
   x.CellValueChanged -= m_Event
   x.CellValueChanged += m_Event

Is one way better / safer than the other?
