Get the ID/Name of a button in a click event. VB.NET

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

Answer 1

Try CType(Sender, Button).Name. Sender is an Object you need to cast to the calling Type in this case Button. If you need more properties from the Sender then use U1199880 's answer. But usually when I am trying to handle multiple clicks I will use the Tag property, assign an index to it. Something like this.

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click
    Dim index As Integer
    If Not Integer.TryParse(CType(sender, Button).Tag.ToString, index) Then Exit Sub

    Select Case index
        Case 0

        Case 1

        Case 2
            ....
    End Select

End Sub

Answer 2

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.

Answer 3

Even simpler:

If sender is btnAnswer1 then ...
