Swap controls in TableLayoutPanel Visual Studio

Question

I have a need to swap controls in a TableLayoutPanel. They are in separate rows. I've tried the suggested code but to no avail. Is there a solution this other than removing all the controls and re adding? The answer can be in C# or VB.

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
    Dim c1 As Control = Me.tlp.GetControlFromPosition(0, 0)
    Dim c2 As Control = Me.tlp.GetControlFromPosition(0, 1)

    If c1 IsNot Nothing And c2 IsNot Nothing Then
        Me.tlp.SetRow(c2, 0)
        Me.tlp.SetRow(c1, 1)
    End If

End Sub

Here is the code to swap controls in a TableLayoutPanel - you have two options.

1) Swap by reference to controls:

Private Sub SwapControls(tlp As TableLayoutPanel, ctl1 As Control, ctl2 As Control)
  Dim ctl1pos As TableLayoutPanelCellPosition = tlp.GetPositionFromControl(ctl1)
  tlp.SetCellPosition(ctl1, tlp.GetPositionFromControl(ctl2))
  tlp.SetCellPosition(ctl2, ctl1pos)
End Sub

It does not depend on where controls are located in TableLayoutPanel - could be different rows, columns or both.

Sample usage:

SwapControls(TableLayoutPanel1, Button1, Button2)

2) Swap by column/row index:

Private Sub SwapControls(tlp As TableLayoutPanel, pos1 As TableLayoutPanelCellPosition, pos2 As TableLayoutPanelCellPosition)
  Dim ctl1 As Control = tlp.GetControlFromPosition(pos1.Column, pos1.Row)
  Dim ctl2 As Control = tlp.GetControlFromPosition(pos2.Column, pos2.Row)
  SwapControls(tlp, ctl1, ctl2)
End Sub

Sample usage:

SwapControls(TableLayoutPanel1, New TableLayoutPanelCellPosition(0, 0), New TableLayoutPanelCellPosition(1, 0))

Solutions are based around TableLayoutPanel.SetRow help article on MSDN and some research on its decompiled representation. Both were tested and deemed working.
