Remarks

Pivot Grid allows you to create calculated fields. They do not obtain their values from fields in the data source. Instead, you specify a binding expression. The expression can be a formula or an aggregate function. You can use the following classes to create a calculated field:

• OLAPExpressionBinding
• ExpressionDataBinding

You can allow users to edit or create new custom expressions in the Expression Editor at runtime. To accomplish this, set the ShowExpressionEditorMenu property to true to add the Expression Editor command to the field’s context menu or call the ShowExpressionEditor method to invoke the Expression Editor.

Use the PivotGridOptionsBehavior.ExpressionEditorMode property to specify the Expression Editor’s version.

Note

You cannot use the Expression Editor dialog in OLAP mode.
