Call sub from child usercontrol

I've got a usercontrol which should call a Sub of the parent page when it was tapped. But I can't reach it with this.Parent (or Me.Parent) and so on.

So how can I access properties and subs from the page class?

You should not call a sub directly from the usercontrol but raise an event and then respond to this event in the Form. I have assumed you are using Winforms.

In the usercontrol:

'declare the event
Public Event ControlClick()

'raise the event when the control is clicked
Private Sub UserControl1_Click(sender As Object, e As System.EventArgs) Handles Me.Click
    RaiseEvent ControlClick()
End Sub

In the Form:

Private Sub UserControl1_ControlClick1() Handles UserControl1.ControlClick
    MessageBox.Show("Control was clicked")
End Sub
