Selection with groups not possible

[Michael]

Hello kendo community,

I have issues with selection on groups in kendo grid. I am trying to use groups and selection with kendo grid and it seems like the selection event trigger does not work in groups, however the checkbox does not apper to be checked. Is there any other solution or is there a way to select multiple rows which are grouped?

Here is a stackblitz demo: https://stackblitz.com/edit/angular-ujcgdv

Hope there is a fix for this.

Best, Mike

Hi Mike,

The reason the Grid is not updated when the checkbox is checked, is that the Angular change detection is not triggered, as the Grid "data" property is bound to a function. Instead, it should be bound to a data collection, a GridDataResult type (an object with "total" and "data" properties) or an Observable of any of those types:

This way the change detection will be triggered appropriately, and the changes in the selection will be reflected in the UI, e.g.:

I hope this helps.
