Remarks

The CustomCellDisplayText event allows customizing the text within data cells. A data cell displays a summary value calculated against a specific Data Field. This field is identified by the event parameter’s PivotCellEventArgsBase<TField, TData, TCustomTotal>.DataField property. The current value and its formatted text representation are specified by the event’s PivotCellEventArgsBase<TField, TData, TCustomTotal>.Value and PivotCellDisplayTextEventArgs.DisplayText properties.

Data cell format settings can be specified via the PivotGridFieldBase.CellFormat, PivotGridFieldBase.GrandTotalCellFormat and PivotGridFieldBase.TotalCellFormat properties.

Use the ASPxPivotGrid.FieldValueDisplayText event or the PivotGridFieldBase.ValueFormat property to customize display text used to represent field values.

Example

The following example shows how to provide custom text for the ASPxPivotGrid’s cells by handling the ASPxPivotGrid.CustomCellDisplayText event.

In this example, if a Grand Total value is less than 50 000, ASPxPivotGrid displays the Low value instead. If the value exceeds 100 000, High is displayed; otherwise, Middle.
