Another Data Grid problem

[Len Morgan]

  I have set a button to contain the custom behavior for my data grid 
table.  However, the selectionChanged is never getting sent.  All of the 
other handlers are being called in that button so I'm not sure what's 
going on.  What I need to do is when a new line is selected, I need to 
get the contents of the first column of the (now) selected row, then get 
the data for that from the database.

Thanks again!
