Hello,
i have a strange error when i am using the grid in batch mode.
even if i have all the values in the grid fields when i press the save changes button,it appears a message box with some required validation errors.I put some validations on the viewModel
something like this
[Required(ErrorMessageResourceType = typeof(Payroll.Resources.Resources),ErrorMessageResourceName = "ValidationMessage_Required")]
public string Name { get; set; }

indeed i put that javascript code
<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);
}
}
</script>
but the validations should active only if i do not have anything in the grid fields.

Why it appears those messages?what could be the error?

Regards,
Daniel

i have a grid where the batch mode is activated code of the view looks like this:

@{
ViewBag.Title = "Measurements";
}

<h2>@ViewBag.Message</h2>

@(Html.Kendo().Grid<Payroll.ViewModels.TallyMeasurementViewModel>()
.Name("Grid")
.Columns(columns => {
columns.Bound(p => p.Code) ;
columns.Bound(p => p.Name) ;
columns.Bound(p => p.MaxLength).Title("Max length");
columns.Bound(p => p.IsActive);
columns.Bound(p => p.IsHour);
columns.Bound(p => p.Precision);
columns.Bound(p => p.Priority);
columns.Bound(p => p.Formula);
columns.Command(command => { command.Destroy().Text("Delete"); }).Width(200);
})
.ToolBar(toolbar =>
{
toolbar.Create().Text("Add");
toolbar.Save().SaveText("Save").CancelText("Cancel");
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Pageable()
.Sortable()
.Scrollable()

.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.ServerOperation(false)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.PkTallyMeasurement))
.Create(update => update.Action("EditingInline_Create", "Home"))
.Read(read => read.Action("EditingInline_Read", "Home"))
.Update(update => update.Action("EditingInline_Update", "Home"))
.Destroy(update => update.Action("EditingInline_Destroy", "Home"))
)
)
<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);
}
}
</script>

the Problem is when i add a new record pressing on Add button,i fill out all the fields with values BUT,in the controller i have an empty viewModel and because i have required on 3 fields,it's normal to get this error message.but why do i have an empty model?

the action for Create is looking like this(in inline mode is called the same action,and it's working ok)
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult EditingInline_Create([DataSourceRequest] DataSourceRequest request, TallyMeasurementViewModel measurement)
{
if (measurement != null && ModelState.IsValid)
{

_tallyMeasurementRepository.Add(AutoMapper.Mapper.Map<TallyMeasurementViewModel,TallyMeasurement>(measurement));
}
return Json(new[] { measurement }.ToDataSourceResult(request, ModelState));
}

I attached the running screen with the message,and the code behind from the controller.
Maybe i am missing some configuration to the grid in order to work in batch mode.

Regads,
Daniel
