Although the CalculatedField.Expression property supports numerous standard functions, operators and constants, for some tasks these may not be enough. Handle the GetValue event, to make a calculated field return a value based on your custom expression.

The GetValueEventArgs class introduces the GetValueEventArgs.Value property, which accepts the final calculated value for a calculated field, and the GetValueEventArgs.Row and GetValueEventArgs.Report properties, which enable you to obtain any information required to calculate a value for a calculated field.
