How to: Set the Background of a Windows Forms Panel Using the Designer
A Windows Forms Panel control can display both a background color and a background image. The BackColor property sets the background color for controls that are contained in the panel, such as labels and radio buttons. If the BackgroundImage property is not set, the BackColor selection will fill all of the panel. If the BackgroundImage property is set, the image will be displayed behind the controls that are contained in the panel.
The following procedure requires a Windows Application project with a form that contains a Panel control. For information about how to set up such a project, see How to: Create a Windows Application Project and How to: Add Controls to Windows Forms.
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 Visual Studio Settings.
