Public Overridable Property BackColor As Color
'Usage
Dim instance As Control
Dim value As Color

value = instance.BackColor

Not applicable.

Property Value

A 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.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.

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.

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 Sub ResetAllControlsBackColor(control As Control)
   control.BackColor = SystemColors.Control
   control.ForeColor = SystemColors.ControlText
   If Me.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

// Reset all the controls to the user's default Control color.

    if (this.get_HasChildren()) {
        for (int iCtr=0; iCtr < control.get_Controls().get_Count(); iCtr++) {
            // Recursively call this method for each child control.
            Control childControl = control.get_Controls().get_Item(iCtr);
            ResetAllControlsBackColor(childControl);
        }
    }
