Question

One way or another I need to link groupID (and one other integer) to the button I am dynamically adding.. any ideas?

What I can do;

AddHandler mybutton.Click, AddressOf PrintMessage

Private Sub PrintMessage(ByVal sender As System.Object, ByVal e As System.EventArgs)
    MessageBox.Show("Dynamic event happened!")
End Sub

What I can’t do, but want to;

AddHandler mybutton.Click, AddressOf PrintMessage(groupID)

Private Sub PrintMessage(ByVal groupID as Integer)
    MessageBox.Show("Dynamic event happened!" & groupID .tostring)
End Sub

Answer 1

There is no way to do this with AddressOf itself. What you’re looking for is a lambda expression.

AddHandler myButton.Click, Function(sender, e) PrintMessage(groupId)

Private Sub PrintMessage(ByVal groupID as Integer)
    MessageBox.Show("Dynamic event happened!" & groupID .tostring)
End Sub
