Question

I have an event in VB.NET to handle several button clicks at once. I need to know which button from the selection kicked off the event. Any ideas how to do this? My code is below:

Private Sub Answer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAnswer1.Click, btnAnswer2.Click, btnAnswer3.Click, btnAnswer4.Click
    'output button ID that caused event
End Sub

I’ve tried sender.Id, e.Id, sender.name, e.name. None of them work

Answer 1

You have to cast the sender to the object type expected.

 Dim btn As Button = CType(sender, Button)

Then you can access what you need.
