Remarks
The CustomCellStyle event fires for each ASPxPivotGridControl’s cell and allows you to customize the appearance of cells dynamically (depending on their contents, position, values of other cells, etc). Use the event’s parameters to identify the processed cell.
PivotGrid allows obtaining a field’s value both for hidden and visible fields. ASPxPivotGrid does not aggregate data by hidden fields. You need to get a value from the underlying data source records corresponding to a processed cell. Use the PivotCellEventArgsBase<TField, TData, TCustomTotal>.CreateDrillDownDataSource method to obtain hidden field’s values. To get a visible field’s value, use the PivotCellEventArgsBase<TField, TData, TCustomTotal>.GetCellValue method.
Example
In this example, the ASPxPivotGrid.CustomCellStyle event is handled to specify custom style settings of individual summary cells displayed within odd rows. The PivotFieldValueStyle.TopAlignedRowValues property aligns field values to the top edge of their cells.
