Kendo Grid Select All checkbox not working for Virtualization Angular

Question

I am working on kendo grid virtualization with Select All feature. Since virtualization is used only visible records will be checked when "Select All" checkbox is checked. I have referred this link where all records would be checked even with pagination. I am trying to achieve the same with virtualization, but as on second scroll records won't be checked by default.

Here is the stackblitz link of what i am trying to achieve https://stackblitz.com/edit/angular-3qtagj?file=app/app.component.html

Please let me know where i am going wrong?

Answer 1

you change Items to query because grid data is query .
