Change Border color DateTime Input

Hi,
I want to change the boarder color of a date time input after the user select a date? I try using in the binding of the property boarder color but doesn't work. Any suggests?? Thanks

if({this.props.value} = "" || {this.props.value} = None,"#DE1B1B","#ADADAD")

It looks as though you are confusing Python scripting and Expression Language. Python uses None. Expression uses null.
Try,

if(
    {this.props.value} = "" || {this.props.value} = null,
    "#DE1B1B",
    "#ADADAD"
)

Tips:

thanks, it's work now
