Hi Sudipta,
Tufale Ashai is right, this question is not for this forum. Should be post to "UI Development Toolkit for HTML5 Developer Center".
With refer to your query, we can not directly control the DateTime through DatePicker API provably. For different DateFormat we have to use model and later need to bind that model into DatePicker.
In the above example you can use different pattern like "yy-MM-dd" , "yyyy-MM-dd", "dd/MM/yyyy", "yyyy/MM/dd" etc. But, if you use "dd/MM/yyyy HH:mm:ss" , you will get incorrect result.
Now, if your requirement is to get the DateTime format like "dd/MM/yyyy HH:mm:ss" into your application there is a another way to get that.
ManageDate.view.js :--
CreateDatePicker.js :--
ManageDate.controller.js :-
index.html :-
The above example is just to show a different way to get the result in that DateTime format. Hope this can help you.
Best Regards,
