kendo ui grid repeat the destroy action on error - asp.net-mvc

Question

I have a grid similar to the code below.
if an errors occurs on destroy action they accumulate.
for example the on the first error 1 call to destroy action, the second 2 calls, the third error 3 calls .......
after some investigation I found out that the items to be sleeted are stored in an array (_destroyed) in the dataSource,
so every time the destroy button is clicked the destroy action is called for each of these items.
I tried assigning null to the _destroyed array but this gave js error when I called destroy action again.
#(Html.Kendo().Grid<someType>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.Name);
columns.Command(command =>
{
command.Edit();
command.Destroy();
}).Width(250);
})
.Editable(editable => { editable.Mode(GridEditMode.PopUp); editable.TemplateName("myTemplate"); })
.Pageable()
.Sortable()
.Filterable()
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(50)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.Id))
.Create(update => update.Action("EditingPopup_Create", "myController"))
.Read(read => read.Action("EditingPopup_Read", "myController"))
.Update(update => update.Action("EditingPopup_Update", "myController"))
.Destroy(update => update.Action("EditingPopup_Destroy", "myController"))
)
<script type="text/javascript">
function error_handler(e) {
if (e.errors) {
var message = "Errors:\n";
$.each(e.errors, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
});
alert(message);
$(".k-grid").each(function () {
var grid = $(this).data("kendoGrid");
if (grid !== null && grid.dataSource == e.sender) {
grid.one('dataBinding', function (e) {
e.preventDefault();
});
grid.dataSource.read();
grid.refresh();
}
});
}
}

Answer 1

You can call the cancelChanges method of the data source and then read. There is no need to call grid.refresh() as it will be called automatically when dataSource.read() is done.

Answer 2

Ok I'm not sure If that's a legitimate answer but this fixed my problem
grid.dataSource._destroyed = [];
grid.dataSource.read();
grid.refresh();
I hope it saves some's time.
