If a Calculation or Reference Error occurs during a calculation, ErrorValue can be used to specify a default value to be used for display or saving. When an error occurs in a calculation, this value will be assigned to the appropriate property of the Context object. For example, in the case of a TextBox's Text property, the property itself will be set to the error value so that it both displays in the TextBox and is saved if the Text property is bound. In the case of an data grid cell, this value will not be displayed, but will be saved to the underlying data source. Objects that do not display or bind, such as a NamedReference, will ignore the ErrorValue.
