Jquery Validation and Datepicker

I get another error from the client side validation. That my date must be a date.:

"The field Date must be a date."

I use: <script src="~/Scripts/bootstrap-datepicker.min.js"></script> <script> $('input.datepicker').datepicker({ format: 'd.m.yyyy' }) </script>

and for the Html Date element i got: <div class="form-group"> @Html.LabelFor(m => m.Date, new { @class = "control-label" } ) @Html.TextBoxFor(m => m.Date, "{0:d}", new { @class = "form-control datepicker" })

Its the same error in Chrome and Edge.

I would also add that i think this issue is related to the European vs American date form. If i pick a date that work both ways I do not get an error. Like 1.1.2017. Seems like the client validation needs the US format. Can this be changed?

I think you may have to use / instead of . in your date format. So d/m/yyyy

Ahh yes, you get validation error when not using "/", thanks dude! Is there a way to use . instead of /, i like the "."-notation better.

By default the jQuery validation extension uses only the "MM/dd/yyyy" format. You can use the jQuery validation globalize (from Nuget) extension to validate the date in a different format. Here is the corresponding stack overflow entry.

According to the docs, you can pass format options when you initialise the datepicker. In the toDisplay function, you could write some code to convert the date from the datepicker to the format that you want to display. I havent tested this, by maybe something like this would do the trick:

$('input.datepicker').datepicker({
    format: {
        toDisplay: function (date, format, language) {
            var d = new Date(date);
            return date.getDate() + "." + date.getMonth() + "." + date.getFullYear();
        },
    }
});
