I set the maxdate property of the datepicker and it does not allow to select any date greater than when clicking the calendar image.

When I enter a date greater than maxdate, it does show the text box bounded by redline.

However, I leave the invalid date and click on save button, it does allow me to fire the event associated with the save button. How do I prevent this happenings?

Hi Raymond,

A possible approach could be to catch the OnError client event and process an appropriate actions afterwards.
Please take a look at the example attached to this post and let me know whether it works for you.
