Checking dynamic button pressed?

I am learning VB.Net at college and I am trying to find a way to check the button clicked by the user in vb.net form. The problem I am currently having is that I have an array of 10x10 buttons, created dynamically in the code.

 For x = 1 To 10
        For y = 1 To 10
            Me.Width = 720
            Me.Height = 720

            boxarray(counter) = New Button
            boxarray(counter).Name = "Box" & x
            boxarray(counter).Location = New Point(x * 48, y * 48)
            boxarray(counter).Width = Me.Width / 15
            boxarray(counter).Height = Me.Height / 15
            boxarray(counter).Visible = True
            boxarray(counter).Cursor = Cursors.Hand
            boxarray(counter).PerformClick()
            Me.Controls.Add(boxarray(counter))
            counter = counter + 1
           Next
        Next

However I need to check the button that the user has clicked, without needing to create subroutines for each individual button, that could be pressed.

First add a Handler

e.g.

Private Sub ArrayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
    ' Handle your Button clicks here
End Sub

Then change boxarray(counter).PerformClick() (which simuates clicking the button) to

AddHandler boxarray(counter), AddressOf ArrayButton_Click

Now all your buttons are linked to one handler. Course now you need to know which one was clicked. Setting the tag property to ((x - 1) * 10) + y - 1 would be one way

Then you could cast sender to Button. Grab the tag and convert it back to x and y in the handler
