Unbound Fields and Expression Editor

Unbound Fields

You can easily add a manually calculated field whose value depends on other fields. To accomplish this task, you need to generally carry out three simple steps. Add a new field, set an option indicating that this field is not going to be bound to a data source and supply data. The third step can be accomplished by writing an event handler or using the Expression Editor dialog described in the following section.

Data Summary Expression Editor

Our WPF and WinForms Pivot Grid Controls can now use the DevExpress Expression Editor to specify summary value calculation formulas. The editor dialog allows you to construct expressions using other summary values. This eliminates the need to write code for complex summary calculation scenarios and also gives end-users control over individual calculations.
