Change the cell position of the Panel dynamically

Question

Hello,

 

I want to change the cell position of the panel at runtime through programmatically, I have Used TableLayoutPanel And for inserting the records into cell i have used panel in each cell.

 

Here is my code

Dim c1 As New Control
Dim c2 As New Control
MainTableLayoutPanel1 = TryCast(c1.Parent, TableLayoutPanel)
If MainTableLayoutPanel1 Is c2.Parent Then 'AndAlso MainTableLayoutPanel1 IsNot Nothing Then
Dim PosC1 As TableLayoutPanelCellPosition = MainTableLayoutPanel1.GetCellPosition(c1)
Dim PosC2 As TableLayoutPanelCellPosition = MainTableLayoutPanel1.GetCellPosition(c2)
MainTableLayoutPanel1.GetCellPosition(PnlLinegraph)
MainTableLayoutPanel1.GetCellPosition(PnlDoughnutChart)
c1 = PnlLinegraph
c2 = PnlDoughnutChart
MainTableLayoutPanel1.SetCellPosition(c2, PosC1)
MainTableLayoutPanel1.SetCellPosition(c1, PosC2)
End If

does any one have better solution on it....?

 

I have got an error (Object Reference not set to an instance of the object)
