Netexpress dialogs supports controls autosize (adjust to the dialogs size) when dialogs are extended/dragged/maximized. Is there any such facility available in Visual cobol winforms?
Windows Forms are not a Micro Focus technology. They are part of the .NET Framework which is from Microsoft. For questions relating to .NET specific topics like resizing Windows Forms it is usually best to check resources like MSDN or Google to find examples in C# or VB.NET.
It looks like the best approach that I can find is to use the Anchor or Dock properties of the controls themselves so that they are relative to the Form.
I found several videos on the subject including a real simple one here.
