Gets or sets the background color for the control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Public Overridable Property BackColor As Colorpublic virtual Color BackColor { get; set; }public:
virtual property Color BackColor {
Color get ();
void set (Color value);
}abstract BackColor : Color with get, set
override BackColor : Color with get, setProperty Value
Type: System.DrawingA Color that represents the background color of the control. The default is the value of the DefaultBackColor property.
The BackColor property does not support transparent colors unless the SupportsTransparentBackColor value of System.Windows.Forms
The BackColor property is an ambient property. An ambient property is a control property that, if not set, is retrieved from the parent control. For example, a Button will have the same BackColor as its parent Form by default. For more information about ambient properties, see the AmbientProperties class or the Control class overview.
Notes to InheritorsWhen overriding the BackColor property in a derived class, use the base class's BackColor property to extend the base implementation. Otherwise, you must provide all the implementation. You are not required to override both the get and set accessors of the BackColor property; you can override only one if needed.
The following code example sets the BackColor and ForeColor of the controls to the default system colors. The code recursively calls itself if the control has any child controls. This code example requires that you have a Form with at least one child control; however, a child container control, like a Panel or GroupBox, with its own child control(s) would better demonstrate the recursion.
