How do I reference a runtime-created button that was pressed?

I've created five buttons with the following code:

Code:
For i As Integer = 0 To 4
            Dim PnlNavigatorButton As New System.Windows.Forms.Button
            Dim ButtonNames() As String = {"Search", "Supervising", "Shipping", "Production", "Data Entry"}

            With PnlNavigatorButton
                .Visible = True
                .Location = New System.Drawing.Point(15, 75 + x)
                .Size = New Size(96, 32)
                .Text = ButtonNames(i)
            End With

            pnlTabNavigator.Controls.Add(PnlNavigatorButton)
            x += 32

            AddHandler PnlNavigatorButton.Click, AddressOf PnlNavigatorButton_Click

        Next
Now I'm working with the PnlNavigatorButton_Click procedure. I imagine that it would look something like:

Code:
Dim control As Control
        For Each control In pnlTabNavigator.Controls
             If control = 'Here's what I'm Missing

        Next
I just don't know how to reference the system event of a button click to perform the if-then test. I know I've seen it somewhere, somewhen, but my dog ate my map back there... I keep thinking it's something like "e.buttonClicked" but none of that shows up in intellisense.
