Grid Editor Template Date Parse issue

[Siobhan McTear]

I have a Grid Editor Template for a Date field and it takes the format dd-MMM-yyyy. However I continuously get the error 'field [property name] is not a valid date'. I have had this issue on a regular view and got round it by using a custom date parsing function and using this to validate dates:

//Manage the JQuery/Kendo date parsing issue
            kendo.culture("en-GB");
            $.validator.addMethod('date',
                function (value, element) {

                    //return this.optional(element) || kendo.parseDate(value)
                    return this.optional(element) || Date.parse(element.value) //Custom function
                });

However this does not appear to work on the Editor Template for a Kendo grid. My Editor Template code looks like the following:

@model DateTime?

@(
    Html.Kendo().DatePickerFor(m => m).Format("dd-MMM-yyyy").ParseFormats(new [] {"dd-MMM-yyyy"})
)


<script src="@Url.Content("~/Scripts/date.js")"></script>
<script src="@Url.Content("~/Scripts/kendo/cultures/kendo.culture.en-GB.min.js")"></script>
<script type="text/javascript">


    $(document).ready(function () {

        kendo.culture("en-GB");
        $.validator.addMethod('date',
            function (value, element) {
                return this.optional(element) || Date.parse(element.value)
            })
    });


    //$('#DateStarted').kendoValidator({
    //    dateValidation: function (element) {
    //        debugger;
    //        var value = $(element).val();

    //        var date = Date.parse(value);
    //        if (!date) {
    //            return false;
    //        }

    //        return true;
    //    }
    //});


</script>

How can i resolve this issue?

Hello,

The grid does not use the jQuery validation but the Kendo Validator. The Kendo Validator uses the formats from the current Kendo culture so you should use a format from the used culture for the datepicker or override the validator mvcdate rule:

$.extend(true, kendo.ui.validator, {
    rules: {
        mvcdate: function (input) {
            if (input.is("[data-val-date]") && input.val() !== "") {
                return kendo.parseDate(input.val(), "dd-MMM-yyyy") !== null;
            }

            return true;
        }
    }
});

Another option would be to modify the short date format in the current culture or use a custom culture with the needed formats.
