What Are Virtual Controls?
Virtual controls are GUI controls (e.g. a check box) that don’t register any memory when used in an interface (e.g. a Table).
Virtual controls can be replicated many times, so that the control appears in different areas with different styles and values.
This allows the GUI interface such as a table to contain millions of rows and columns with controls in every cell.
