How to: Group Controls with the Windows Forms Panel Control Using the Designer
Windows Forms Panel controls are used to group other controls. There are three reasons to group controls. One is visual grouping of related form elements for a clear user interface; another is programmatic grouping, of radio buttons for example; the last is for moving the controls as a unit at design time.
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Customizing Development Settings in Visual Studio.
To create a group of controls
Drag a Panel control from the Windows Forms tab of the Toolbox onto a form.
Add other controls to the panel, drawing each inside the panel.
If you have existing controls that you want to enclose in a panel, you can select all the controls, cut them to the Clipboard, select the Panel control, and then paste them into the panel. You can also drag them into the panel.
