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:

• e.ColumnField
• e.DataField
• e.RowField

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

• e.ColumnIndex
• e.RowIndex

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.

View Example: Pivot Grid for WPF - Hide Column Totals

MainWindow.xaml.cs

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

MainWindow.xaml.vb

Private Sub PivotGridControl1_CustomCellValue(ByVal sender As Object, ByVal e As PivotCellValueEventArgs)
    If e.ColumnValueType = FieldValueType.GrandTotal AndAlso e.DataField Is fieldDiscount Then
        e.Value = Nothing
    End If
End Sub
