DataGridview SelectionChanged Event : Strange Behavior

This the second time I posted, I am a MSDN Universal Subscriber, please answer my question...

When I fill a dataGridView with data, the SelectionChanged Event seems to fire too many times. If I assign the dataSource to the Grid In Form_Load, the SelectionChanged Event fires 5 times. If I assign the datasource to the Grid using a Button Press, then the SelectionChanged Event Fires 3 times.

I am expecting the event to fire only once, as the Grid Loads when first cell or row is selected.

I have the SelectionMode = RowHeaderSelect

I am using VS2005 Professional CTP July.

Is there a problem with this event?
