I need to add a 0 to the mask's start, but it does not accept 0 as a value.
Hello Mario,
Thank you for contacting the Infragistics support!
I have tried to reproduce the described issue but I was not able to.
Can you please provide an isolated sample that reproduces this misbehavior in order for me to investigate it further? In addition, could you also tell if this is reproduced in all browsers on your side?
I am looking forward to your response!
