The event data class exposes the following methods:

Method Description
CreateDrillDownDataSource() Returns a list of records used to calculate a value for the current cell. Inherited from PivotCellBaseEventArgs.
CreateDrillDownDataSource(List<String>) Returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns to return. Inherited from PivotCellBaseEventArgs.
CreateDrillDownDataSource(Int32, List<String>) Returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns and limit the number of records to return. Inherited from PivotCellBaseEventArgs.
CreateOlapDrillDownDataSource(List<String>) Obsolete. In OLAP mode, returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns to be returned. Inherited from PivotCellBaseEventArgs.
CreateOlapDrillDownDataSource(Int32, List<String>) Obsolete. In OLAP mode, returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns and limit the number of records to be returned. Inherited from PivotCellBaseEventArgs.
CreateServerModeDrillDownDataSource(List<String>) Obsolete. In server mode, returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns to be returned. Inherited from PivotCellBaseEventArgs.
CreateServerModeDrillDownDataSource(Int32, List<String>) Obsolete. In server mode, returns a list of records used to calculate a summary value for the current cell. Allows you to specify the columns and limit the number of records to be returned. Inherited from PivotCellBaseEventArgs.
CreateSummaryDataSource() Returns a summary data source. Inherited from PivotCellBaseEventArgs.
GetCellValue(PivotGridField) Returns a cell value calculated for the current column and row field values, against the specified data field. Inherited from PivotCellBaseEventArgs.
GetCellValue(Int32, Int32) Returns a cell value by the column and row indexes. Inherited from PivotCellBaseEventArgs.
GetCellValue(Object[], Object[], PivotGridField) Returns a cell value calculated for the specified column and row field values, against the specified data field. Inherited from PivotCellBaseEventArgs.
GetColumnFields() Returns an array of column fields which correspond to the processed cell. Inherited from PivotCellBaseEventArgs.
GetColumnGrandTotal(PivotGridField) Returns a Column Grand Total value calculated for the current row field values, against the specified data field. Inherited from PivotCellBaseEventArgs.
GetColumnGrandTotal(Object[], PivotGridField) Returns a Column Grand Total value calculated for the specified row field values, against the specified data field. Inherited from PivotCellBaseEventArgs.
GetFieldValue(PivotGridField, Int32) Returns the specified column or row field’s value for the cell, addressed by its zero-based index in the Data Area. Inherited from PivotCellBaseEventArgs.
GetFieldValue(PivotGridField) Returns the value of the specified column or row field which identifies the column/row in which the processed cell resides. Inherited from PivotCellBaseEventArgs.
GetGrandTotal(PivotGridField) Gets the Grand Total for the specified field. Inherited from PivotCellBaseEventArgs.
GetNextColumnCellValue(PivotGridField) Returns the value of the cell in the same row but in the next column. Inherited from PivotCellBaseEventArgs.
GetNextRowCellValue(PivotGridField) Returns the value of the cell in the next row. Inherited from PivotCellBaseEventArgs.

InvokeEventHandler(Delegate, Object) When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
IsFieldValueExpanded(PivotGridField) Indicates whether the specified field’s value that represents a row or column header of the processed cell is expanded. Inherited from PivotCellBaseEventArgs.
IsFieldValueRetrievable(PivotGridField) Gets whether the value of the specified column or row field can be retrieved for the current cell by the PivotCellBaseEventArgs.GetFieldValue method. Inherited from PivotCellBaseEventArgs.
IsOthersFieldValue(PivotGridField) Indicates whether the processed data cell resides within the “Others” row/column when the Top N Value feature is enabled. Inherited from PivotCellBaseEventArgs.
OnSetSource(Object) When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

The CustomCellValue event fires after all control calculations when cell values are filtered, grouped, and sorted. Handle the event to replace the calculated cell values with custom values. You can create custom calculations in the event handler and assign the result to the e.Value property. Use the event parameter’s SummaryValue property to obtain the summary value calculated for the cell.

Use the following event parameter’s properties to obtain the fields that correspond to the processed cell:

Use the following event parameter’s properties to obtain the visual indices of the column and row that contain the cell:

You can also enable custom display text in the PivotGridControl.CustomCellDisplayText event that is raised after the CustomCellValue event.

Note

The Pivot Grid uses values from the CustomCellValue and CustomCellDisplayText events only to represent data. The control does not take these values into account when sorting, filtering, or calculating data because these operations have already completed when the events occur.

Example: Hide Column Totals

This example demonstrates how to handle the CustomCellValue event to hide the Discount field grand totals.

Hide column totals

private void PivotGridControl1_CustomCellValue(object sender, PivotCellValueEventArgs e) {
    if (e.ColumnValueType == FieldValueType.GrandTotal
           && e.DataField == fieldDiscount)
        e.Value = null;
}
