Hi Jeffrey,

I'm afraid that there is no public API function available for this operation.
However, there's an internal method of the igDataSource that you can use without any problems: _addChangesSuccessHandler.

Here's an example of how to get the status of the request after it has arrived:

<script type="text/javascript">
    $(function () {
        $("#Grid1").live("iggridrendered", function (evt, ui) {
            $("#Grid1").data("igGrid").dataSource._addChangesSuccessHandler(function (data, textStatus, jqXHR) {
                alert("Request status: " + textStatus);
            });
        });
    });
</script>

I'm also attaching an MVC3 sample demo'ing the solution.

Cheers,

                   I am batching my updates back to the server and in the event where some of my records fail server side validations(lets say 2 out of 10 modified records), i am doing a rollback  and sending the JSON response like mentioned in the sample: https://www.igniteui.com/grid/basic-editing. 

At this point none of the records are committed back to the server. My problem is after user corrects the validation error(for the two records), and saves, only the 2 correct records are there in the transactionlist... 

  List<Transaction<ResultMetaData>> transactions =
                    m.LoadTransactions<ResultMetaData>(HttpContext.Request.Form["ig_transactions"]);

Though the gird shows the changes, I am unable to access the other 8 records in my controller. 

Please advice if you need more details/clarifications and suggest how I can handle failed cases when batching my updates.

Thank You,

Hari

$('#Grid1').igGrid('option', 'dataSource')

$("#Grid1").data("igGrid").dataSource

This on the other hand gives you access to the igGrid's internal igDataSource object.
I know that may not look like an out-of-the-box solution, but actually you end up accessing internal components of any jQuery UI widget, you end doing so through data().

Cheers,
Borislav
