Inheritance
System.Object
CalculatorControl
Namespace: Syncfusion.Windows.Forms.Tools
Assembly: Syncfusion.Tools.Windows.dll
Syntax
public class CalculatorControl : ContainerControl, ICalculatorEngineParent, ICalculatorButtonParent, IThemeProvider, IVisualStyle
Remarks

The calculator control can be used in two different layouts. See CalculatorLayoutTypes for more information.

The default property of the Calculator Control class is the Value property. This property is of type CalculatorValue.

The Calculator Control uses a Syncfusion.Windows.Forms.Tools.CalculatorControl.CalculatorEngine object to perform the calculations and maintain the state of the calculations. The CalculatorControl implements the ICalculatorEngineParent interface to receive notifications from the Calculator Engine.

The calculator buttons are of type Syncfusion.Windows.Forms.Tools.CalculatorButton and the buttons maintain their own information about the action that is to be performed when clicked.
