VB.NET: Can I rewire button events to handle several different button clicks through one click event

I have a form with 5 buttons that simply click through a datatable.  The buttons are FIRST, LAST, PREVIOUS, NEXT and NEW.  For the sake of discussion lets say the buttons are named btnFIRST, btnLAST, etc...
Instead of coding through 5 separate button events to call one subroutine (and pass the button object to the subroutine), is there a way that I can do an AddHandler or something to allow the one added event to handle  the clicks of any and all buttons?

Sure...you can either:

    Use the "Handles" keyword and list MULTIPLE controls afterwards
    < or > 
    Wire them all up at run-time with AddHandler()

In either case, the "sender" parameter will tell you which button fired the event:
    Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFIRST.Click, btnLAST.Click, btnPREVIOUS. Click, btnNEXT.Click, btnNEW.Click

        Dim SourceButton As Button = CType(sender, Button)

        ' ... do something with "SourceButton" ...

    End Sub

First and foremost, both of your solutions are terrific because I had no cliue they existed.  I was aware of Addhandler(), and planned on wiring the events at run time... but if I did that, then anytime I clicked on one of the buttons in the GUI designer it would create a new solo event for me.

I didn't know about the multiple handles capability of HANDLES...  I added
Handles btnFIRST.Click, btnLAST.Click, btnPREVIOUS. Click, btnNEXT.Click, btnNEW.Click

Now when I click on any of the buttons the GU designer redirects me to the one event!!! It's perfect!  Thanks!!!
I'm splitting the points and getting out of here before a fight breaks out....  I got what I needed <grin>!
