Gets or sets the background color for the control.
public:
virtual property System::Drawing::Color BackColor { System::Drawing::Color get(); void set(System::Drawing::Color value); };public override System.Drawing.Color BackColor { get; set; }member this.BackColor : System.Drawing.Color with get, setPublic Overrides Property BackColor As ColorProperty Value
A Color that represents the background color of the control. The default is the value of the DefaultBackColor property.
Examples
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.
// Reset all the controls to the user's default Control color.
private:
void ResetAllControlsBackColor( Control^ control )
{
control->BackColor = SystemColors::Control;
control->ForeColor = SystemColors::ControlText;
if ( control->HasChildren )
{
// Recursively call this method for each child control.
IEnumerator^ myEnum = control->Controls->GetEnumerator();
while ( myEnum->MoveNext() )
{
Control^ childControl = safe_cast<Control^>(myEnum->Current);
ResetAllControlsBackColor( childControl );
}
}
}
// Reset all the controls to the user's default Control color.
private void ResetAllControlsBackColor(Control control)
{
control.BackColor = SystemColors.Control;
control.ForeColor = SystemColors.ControlText;
if(control.HasChildren)
{
// Recursively call this method for each child control.
foreach(Control childControl in control.Controls)
{
ResetAllControlsBackColor(childControl);
}
}
}
' Reset all the controls to the user's default Control color.
Private Sub ResetAllControlsBackColor(control As Control)
control.BackColor = SystemColors.Control
control.ForeColor = SystemColors.ControlText
If control.HasChildren Then
' Recursively call this method for each child control.
Dim childControl As Control
For Each childControl In control.Controls
ResetAllControlsBackColor(childControl)
Next childControl
End If
End Sub
Remarks
The BackColor property does not support transparent colors unless the SupportsTransparentBackColor value of System.Windows.Forms.ControlStyles is set to true.
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.
Starting with Windows Vista and depending on the theme, setting this property might not change the appearance of the calendar. For example, if Windows is set to use the Aero theme, setting this property has no effect. This is because an updated version of the calendar is rendered with an appearance that is derived at run time from the current operating system theme. If you want to use this property and enable the earlier version of the calendar, you can disable visual styles for your application. Disabling visual styles might affect the appearance and behavior of other controls in your application. To disable visual styles in Visual Basic, open the Project Designer and uncheck the Enable XP visual styles check box. To disable visual styles in C#, open Program.cs and comment out Application.EnableVisualStyles();.
Notes to Inheritors
When 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.
