you could create a generic event and add all of the buttons to it in the
Handles clause.

The DirectCast statement simply converts the "sender" variable (which is
declared as an Object) to a Button. Essentially, if you click on Button1
you
get Button1 passed to the Click event handler as an object. Cast it back
to
a Button and you can do anything you want with it including accessing
it's
properties such as name, text, position, etc....

See this discussion for some more information. It's a very similar
problem... at least the part about adding multiple buttons...

Remember in VB.NET you can have a single event handler handle multiple
events (as above) and you can have a single event handled by multiple
handlers...

Private Sub Stuff1(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
End Sub

Private Sub Stuff2(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MenuItem2.Click
End Sub

Private Sub Stuff3(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MenuItem2.Click,
Button1.Click

End Sub

In the above if you click Button1: Stuff1 & Stuff3 will execute, if you
click MenuItem2: Stuff2 & Stuff3 will execute.

In addition to the Handles keyword, you can use AddHandler &
RemoveHandler
to handle an event.
