TableLayoutPanel doesn't show vertical scrollbar even when AutoScroll is set to True

I have TableLayoutPanel set on a Panel and I have AutoScroll set to True for both these.

The TableLayoutPanel is made of only 1 row and 1 column at design time. At run time I am adding a chart to new row (starting at row index 1), with no columns added. The chart is docked into the row cell.

However, I don't see vertical scrollbar to scroll the charts. Initially, I didn't had the Panel, since TableLayoutPanel wasn't showing any scrollbar I added Panel, but of no use.

Can you please test the attached code and suggest fix?

Ideally I would like to use only TableLayoutPanel (without Pane) if possible.
