"selection aggregate" functionality does not display sum.

[CARLOS]

I have a grid that I make a request for and when the number column is selected, it is not displaying the sum in the toolbar.

Here's the example in stackblitz:

Hi Carlos,

Thank you for the provided example.

Firstly, I observed that both the data property and the data binding directive are being used in the Grid, which is not considered a correct configuration. The Grid should utilize either the data or the data binding directive. Documentation on the data binding:

https://www.telerik.com/kendo-angular-ui/components/grid/data-binding/local-data/

I assume that this was the setup due to an error that occurs if only the data property binding is used. It seems that when the data is slightly delayed it breaks the selection logic which is considered a bug on our side:

A workaround for this would be to ensure that the data is available before initializing the Grid component using the ngIf directive:

Our team apologizes for the inconvenience caused by the bug until it is resolved on our side.
