Description

I'm trying to implement a select all for external paging (i.e. one that selects all possible rows, even those not retrieved from the server yet). I keep a list of selected row identifiers on the client and, if needed, re-select rows when a user pages (i.e. gridRow.isSelected = true).

Is there a way to listen for when the user clicks on the select all checkmark? When the user clicks on the checkmark, I'd like to retrieve all possible row identifiers from the server and store them on the client-side. My current solution is to listen for rowSelectionChanged and rowSelectionChangedBatch and check if gridRows.length == paginationPageSize.

This is somewhat related to https://github.com/angular-ui/ui-grid/issues/1636#issuecomment-128110515

Research direction
To implement a select all event, examine the UI Grid selection logic in the source code, likely in the selection feature directory. Look for existing methods like 'toggleSelectAll' or 'isSelected'. Check the linked issue (#1636) for related discussion. Consider adding a new event emission when all rows are selected via the header checkbox. Ensure the event includes the total count or identifiers of selected rows.
