Remarks

Pivot Grid uses the Binding API to bind Pivot Grid fields to data. A data binding source can be a column in the data source or a calculated expression.

The following types of bindings are available:

Column Binding: Allows you to bind a Pivot Grid field to a data column in the data source. The Pivot Grid field obtains its values from a field in the data source.
Expression Binding: Allows you to bind a Pivot Grid field to an expression and display the calculated result. The expression can be a formula or an aggregate function.
Calculation Binding: Allows you to bind a Pivot Grid field to a window calculation and display aggregated values in the window.

The following classes are used to create calculation bindings:
