Thank you for your response Sir.
I was able to apply the custom Date format with that approach.
I have set the DisplayFormat to Long and have a custom property Longdateformat to "dd-MMM-yyyy" and displays the value properly.
With those property set, I can input the following and have the display format of "28-Feb-2021"
28-feb-2021
02-28-2021
But when I input 28-02-2021 it displays an error.
Is it possible to accept the 28-02-2021 since the display format is "dd-MMM-yyyy"?
