This sample demonstrates aggregate functionality of the Grid. In this sample, the aggregate value for the column “Freight” is displayed in column footer.
The Grid supports aggregates which will be displayed at the footer, group footer and group caption of the Grid. The
aggregate configurations can be provided by the
aggregates
property.
The built-in aggregates are,
SumAverageMinMaxCountTrueCountFalseCountCustom - Requires the
customAggregate
property to perform aggregation. The custom aggregate value can be accessed inside template using the
key custom
In this demo, the
footerTemplate property is used to display four different aggregates in the Grid footer. In the first
aggregate row, the sum aggregate type is used by setting the
type and
field property as Freight which will be used to perform the aggregation. The
aggregate value is accessed inside the
footerTemplate using its
type name (sum). The aggregate value will be formatted based on its
format value(C2) before being displayed.
Injecting Module:
Grid component features are segregated into individual feature-wise modules. To use aggregate feature, we need to inject
Aggregate into the provide section.
