• Calculation

  The CustomSummary event fires for each data row in a grid or in a group. The event’s SummaryStage property value is Calculate. Use this stage to calculate a summary value.

  You can set the TotalValueReady property to true at the Initialization stage to skip the Calculation stage and calculate a custom summary at the Initialization or Finalization stage.
