| Object | An object specifying the total summary value. |
Remarks
Important
This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.
TotalValue is the total summary value that accumulates the custom calculated value. Note that this property should be initialized before the summary calculation process starts. To identify the status of the custom summary calculation, use the CustomSummaryEventArgs.SummaryProcess property. When performing calculations, you need to refresh the TotalValue property for it to be updated with the new values.
You can also modify the TotalValue property’s value when finalizing the calculation. In this case, the CustomSummaryEventArgs.SummaryProcess property returns the CustomSummaryProcess.Finalize value.
Example
This example shows how to use the GridControl.CalculateCustomSummary event to create a custom summary that counts the total number of data rows whose cells in the Shipped column (SwitchColumn) contain false.
