C # Use panel to switch sub-Forms

During today's programming, we encountered a problem: loading two different forms in the same form area, displaying only one subform at a time, and being able to switch between the two subforms.

The panel control is very simple to solve this problem. You only need to clear the child form on the panel control each time and load another child form. The Code is as follows:

Panel1.Clear (); // clears the child form on the current panel.

Panel1.Add (subtabcontrol); // subtabcontrol is another subform.
