GridControl.OptimizeSummaryCalculation Property

Specifies whether to optimize summary calculation. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v23.2.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

Public Property OptimizeSummaryCalculation As Boolean

Property Value

Type	Description
Boolean	true to recalculate data summaries only for the changed record; false to recalculate summaries for all records.

Remarks

We recommend that you optimize summary calculation in the following case:

• The GridControl is bound to an ObservableCollection<T> whose items implement the INotifyPropertyChanged and INotifyPropertyChanging interfaces.
• Columns with summaries are not unbound columns.
• You do not use custom summaries.
• You do not lock the GridControl to process updates in batches.

Refer to the following topic for information on how to optimize data updates within the GridControl: Frequent Data Updates.
