Remarks
The CustomCellValue event fires for each cell after the control structure is calculated. You can handle the event to replace the calculated cell values with custom ones. Use the event parameter’s PivotCellBaseEventArgs.SummaryValue property to obtain the summary value calculated for the cell. The custom cell value should be provided to the PivotCellValueEventArgs.Value property. To specify whether to run the default event handler, use the event parameter’s Handled property. If it is set to false, the custom cell value is ignored.
Use the event parameter’s PivotCellBaseEventArgs.ColumnField, PivotCellBaseEventArgs.DataField and PivotCellBaseEventArgs.RowField properties to obtain the column, data and row fields that correspond to the processed cell, respectively. The PivotCellBaseEventArgs.ColumnIndex and PivotCellBaseEventArgs.RowIndex properties are used to obtain the visual indices of the column and row that contain the cell.
You can also provide custom display text by handling the PivotGridControl.CustomCellDisplayText event, which is raised after the CustomCellValue event.
Noe that you cannot use values provided by the CustomCellValue event to sort data because at this moment sorting is already completed. In this case, use the PivotGridControl.CustomSummary event instead.
