Is there a chance to add support for some numeric systems? like hex, octal and/or binary. Could be a property like "NumericSystem" or "NumericBase".
Eg:
<SfInput:SfNumericEntry Value="255"
NumericSystem="Hex" /> // will show "FF", and allow the user to input caracters from '0' to '9' and 'A' to 'F'
<SfInput:SfNumericEntry Value="255" NumericSystem="Octal" /> // will show "377", and prevent de input of '8' and '9' char
<SfInput:SfNumericEntry Value="255" NumericSystem="Binary" /> // will show "11111111", and prevent the input of digits others than '0' or '1'
In addition, if possible, another property to allow "group" digits, like "CharGroup=2", so if u have a value of 65535 in 'Hex' mode, "FFFF" can be displayed as "FF FF". Tecnically could be compatible with CustomFormat property, this way can also do:
<SfInput:SfNumericEntry Value="255" NumericSystem="Hex"
CustomFormat = "0000"/> // 00FF
<SfInput:SfNumericEntry Value="15" NumericSystem="Binary" CustomFormat = "D8"
/> // 00001111
