Current behavior Repro steps:

• Grid uses multi-checkbox, for instance, to display 100 items
• One row is disabled using condition with displayCheck
• User checks the "Select All" checkbox at the top of the grid to select all rows (except disabled rows)
• Using "selectCheck" I can filter out the disabled rows
• BUG - At this point, the footer will show 100 selected / 100 total

Expected behavior

The expected behavior is that if there are 100 total items and one row is disabled, if the Select All checkbox is checked, then the footer should display only the count of actual selected items.

Reproduction of the problem

The bug can be reproduced via ngx-datable's own demo on your website: http://swimlane.github.io/ngx-datatable/#chkbox-selection

Screenshot attached to illustrate further.

What is the motivation / use case for changing the behavior?

To display correct information on the footer of the grid.

i have similar issue when y have checked a row and uncheck this selected label is not updated

[venimus]

it's 2023 this issue is still there. I use

onSelect({ selected }) {
    this.selected.splice(0, this.selected.length);
    this.selected.push(...selected.filter(this.displayCheck));
}

but visually it is awkward

seems that the problem is that selectCheck is not called for "select all"
