Popup Editing with DateTime can not be saved

[Andreas]

In your sample: http://www.kendoui.com/code-library/mvc/grid/custom-popup-editor.aspx

When I want to save I get an error that the field birthdate must be a date.

I even set DataType.Date annotation on that model property. But still I get this error.

How can I fix your broken sample?

[Andreas]

It seems when I once set a date via datepicker then I can save and do not get an invalid modelstate.

Why is that?

[Andreas]

Odd... that seemed only to work once, when I tried to submit my form again and changing the dates before still I can not submit the form as the dates are invalid...

[Andreas]

could it be that is a culture problem?

Hello Andreas,

Indeed the issue seems to be caused by difference in the format and the validation. By default if you change the format of a widget the validation will still use the culture information and validate against it. Similar question here:

In order to tell where exactly the issue is coming from please demonstrate your case with a small demo. Thank you for the understanding.

Kind Regards,
