My setting is that i use virtual scrolling in grid with selection. My problem is I will select all entries not only the first page of virtual scrolling. But the event parameter of onSelectionChange had no indicator for selection all click. When noting is selection this example works:
public onSelectionChange(event: SelectionEvent) {
    if (event.selectedCells.length === this.pageSize) {
      // selected all click?
        this.selectedKeys= this.data.map(data => data.id);
    }
    if (event.deselectedCells.length === this.variableDataService.pageSize) {
      // selected nothing click?
        this.selectedKeys= [];
    }

Hello Steffen,

For more details on how to select all rows regardless of the page size, please check the following article from our documentation:

Here is an example with virtual scrolled Grid:
