Recently I have coded a simple software using C# in Visual Studio 2019. In the software, there is only 1 windows from (form 1) and five User Control windows. 
As you can see, from the windows form, I can access each of the user control panel by clicking the ribbon Button on the left.
This software is running as I desired on my computer. But whenever I installed it in a computer with small display Monitor or lesser resolution, the full screen mode of the software can't adjust the windows form or control panel. It opened on full screen but many items at the bottom part gets doesn't show. Also no scrollbar comes out in the full screen mode although I have enable it in the windows form Property.
Could you please help me in this regard.
I am very new at this. I have started to learn programming recently.
