Collapsible Panel - Hidden Panel - Programmatically Control if it is expanded or not.

[Mark]

I want to control a collapsible panel programmatically.  Also, I want the button section at the top hidden.  So far, I have that part working.  I also have the expanding/collasping working as well, but I have run into a problem. When I collapse the panel, the panel does not collapse all the way, it still sticks out a little bit, by like 12-14 pixels (in this case, on the bottom).  This is a problem for me, as I am expecting that entire space to be gone.

 

This is the Collasible Panel, where I have hidded the Header Panel and IsExanded is set to false:

 

This is the designer.cs part.  I am not sure what I am missing. What else to I need to do to make the panel have a height of 0.
