NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation
#Declaration
#Remarks
The UpdateTotalSummary method can be used to force summary values recalculation. Such manual summary updates should be used in the following cases.
- When a View displays a large amount of data, automatic summary updates may slow down your application. Thus, you may disable automatic updates using the GridOptionsBehavior.AutoUpdateTotalSummary option. In this case, you should manually call the UpdateTotalSummary method each time summary values need to recalculated.
- When a custom aggregate function is implemented using the GridView.CustomSummaryCalculate event, summary values may not only depend on the data displayed by the View. If summaries depend on external data, you should call the UpdateTotalSummary method each time this external data is changed.
