OnActionComplete event fires before the page change has occured?

[Patrice Tremblay]

I register a handler for the OnActionComplete where I handle the Syncfusion.Blazor.Grids.Action.Paging event, calling the following handler:

        private async Task OnPageChanged(ActionEventArgs<MeasurementListingGridItem> args)

        {

            var records = (await _gridObj.GetCurrentViewRecords()).Select(m => m.SerialNumber).ToArray();

            Logger.LogDebug($">> Page changed: {args.PreviousPage} -> {args.CurrentPage}, {records.Length} records, from {records[0]} to {records[^1]}.");

        }

Page 1 of my grid shows 10 items, Page 2 shows 7 items. 

Alternating between page 1 and 2 produces the following log:

2021-04-28 16:23:54.643 -04:00  [DBUG]  >> Page changed: 1 -> 2, 7 records, from SN06694268 to SN06690046. 

2021-04-28 16:24:05.812 -04:00  [DBUG]  >> Page changed: 2 -> 1, 7 records, from SN06694268 to SN06690046. 

2021-04-28 16:24:16.000 -04:00  [DBUG]  >> Page changed: 1 -> 2, 10 records, from SN06694281 to SN06690050.

2021-04-28 16:24:20.693 -04:00  [DBUG]  >> Page changed: 2 -> 1, 7 records, from SN06694268 to SN06690046. 

2021-04-28 16:24:49.410 -04:00  [DBUG]  >> Page changed: 1 -> 2, 10 records, from SN06694281 to SN06690050.

2021-04-28 16:24:51.271 -04:00  [DBUG]  >> Page changed: 2 -> 1, 7 records, from SN06694268 to SN06690046. 

As can be observed, the first event (1 -> 2) correctly reports 7 records with the serial numbers matching what is displayed.

But then, it's as if the GetCurrentViewRecords() was always reporting the content of the previous page. 

In the UI, the displayed content is correct (page 1 displays 10 items and page 2 displays 7 items).

Any ideas?
