Declaration

C#

public event CalculatorCustomErrorTextEventHandler CustomErrorText

VB.NET

Public Event CustomErrorText As CalculatorCustomErrorTextEventHandler

Event Data

The CustomErrorText event's handler receives an argument of the CalculatorCustomErrorTextEventArgs type. The following properties provide information specific to this event:

Property	Description
ErrorText	Gets or sets the error description.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

Remarks

The CustomErrorText event if fired after an error has occurred during calculations (e.g. division by zero). Handle this event to replace the default error text with custom text. To do this, use the CalculatorCustomErrorTextEventArgs.ErrorText property.

NOTE

If the calculator has the digital display (the Calculator.IsDigitalDisplay property is set to true), handling the CustomErrorText event has no effect. If there is an error, the calculator displays 'Error'.
