This was a sample of my code with a MVC view.  The m is the Model instance in a foreach loop - foreach(var m in Model) 

 <script type="text/javascript">
                $(function () {
                    //function that handles the result after the updates

                 $("#Grid_@m.QuotaID").data("igGrid").dataSource._addChangesSuccessHandler(function (data, textStatus, jqXHR) {
                        alert("Request status: " + textStatus);
                        });
                    });

            </script>

            <script type="text/javascript">
                $(function () {
                    //function that handles the result after the updates

                 $("#Grid_@m.QuotaID").data("igGrid").dataSource._addChangesErrorHandler(function (data, textStatus, jqXHR) {
                        alert("Request FAILURE status: " + textStatus);
                        });
                    });

            </script>

Hello - I believe I had the same confusion about this and how to handle the FAILUREs.  I would point out that there is the ability to handle the Failure message with a 2nd function when calling the saveChanges method..  See the documentation screenshot

I can answer my own question.

I had this in my code:

$("#TimesheetGrid").data("igGrid").dataSource._addChangesSuccessHandler(changesSuccessHandler);
$("#TimesheetGrid").igHierarcichicalGrid("saveChanges");

which doesn't work. It did save the changes but didn't fire changesSuccessHandler.

I tried this:
$("#TimesheetGrid").data("igHierarcichicalGrid").dataSource._addChangesSuccessHandler(changesSuccessHandler);
$("#TimesheetGrid").igHierarcichicalGrid("saveChanges");

which didn't work either - didn't even save the changes.

I then changed the saveChanges to reference via igGrid instead of igHierarchicalGrid and it worked fine - data saved and changesSuccessHandler called:

$("#TimesheetGrid").data("igGrid").dataSource._addChangesSuccessHandler(changesSuccessHandler);
$("#TimesheetGrid").igGrid("saveChanges");

Sometimes just asking the question presents the answer.

Hi

Should this work OK with an igHierarchicalGrid?

I have got it working fine for a normal igGrid but when I use the same technique with a hierarchical grid my equivalent of the "test" function never gets called.

eg this works on my invoice page with igGrid and the function named "changesSuccessHandler" is called:

        $("#InvoiceGrid").data("igGrid").dataSource._addChangesSuccessHandler(changesSuccessHandler);

this does not work on my timesheet page with a igHierarchicalGrid - "changesSuccessHandler" is never called:

        $("#TimesheetGrid").data("igGrid").dataSource._addChangesSuccessHandler(changesSuccessHandler);

Regards,

Graeme

Hi Flavio,

change this:

$("#myGrid").data("igGrid").dataSource._addChangesSuccessHandler( test() );

to this:

$("#myGrid").data("igGrid").dataSource._addChangesSuccessHandler( test);

the handler shouldn't be a function invocation like test(), but the actual reference itself , that is "test" itself - without the quotes.

Hope it helps
