Hello,
I try datetimepickerfor control on a mvc project, I set min and max values for it, when I change time, it validates for min, max values and changes automatically but not for date, so I had to write script below. 
Regards.

function dateChange(){
        if (this.value() < this.min()) {
            this.value(this.min());
        }
        else if (this.value() > this.max()) {
            this.value(this.max());
        }
    }
