CalculatedField.GetValue Event

Occurs when a calculated field obtains its value, enabling you to return a custom value for this calculated field.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v18.1.dll


public event GetValueEventHandler GetValue

The event handler receives an argument of the GetValueEventHandler type.

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.
