Get the name of the button that triggered the event

I have an event handler that handles the click event of multiple buttons: 

Private Sub primeHandler(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _2s.Click, _3s.Click, _4s.Click, _5s.Click, _6s.Click

End Sub

_2s, _3s, etc are all buttons. Now I need a way to determine which button triggered the event and also get the button's name as string. Any way to do that? Thanks

You can cast sender to type Button and access the Name property.

Private Sub primeHandler(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _2s.Click, _3s.Click, _4s.Click, _5s.Click, _6s.Click
    Dim myButton As Button = CType(sender, Button)
    Dim myName As String = myButton.Name
End Sub

Use sender - it's what it's designed to do.

MessageBox.Show((sender as Button).Name);

If you're going to use it more than once, assign it to a variable to make it easier.

var button = (sender as Button);
MessageBox.Show(button.Name);
