NuGet Package: DevExpress.Blazor

#Declaration

C#

#Property Value

Type Description
Boolean

true to skip the calculation stage; otherwise, false.

#Remarks

The summary calculation consists of three stages:

Initialization
The CustomSummary event fires once at this stage. The event’s SummaryStage property value is Start. Use this stage to initialize a summary value (for example, reset internal counters).
Calculation
The CustomSummary event fires for each data row in a TreeList. The event’s SummaryStage property value is Calculate. Use this stage to calculate a summary value.
Finalization
The CustomSummary event fires once at this stage. The event’s SummaryStage property value is Finalize. Use this stage to assign the calculated summary value to the TotalValue property.

You can interrupt summary calculations at any time. To do so, set the TotalValueReady event argument to true.

Refer to the TreeListCustomSummaryEventArgs class description for more information and an example.
