Problematic Masks:
FormatHelper:ToInputMask("CHARACTER", "!(4)x(8)")
The ! sign means that the following four letters will be uppercased.
Infragistics does not support this functionality like Progress does.
Either the full Mask will be uppercased by adding the > sign at the
beginning or nothing will be upper or lowercased.
Infragistics only supports converting all following characters.
> Convert all the characters that follow to uppercase.
< Convert all the characters that follow to lowercase.
Uppercasing the InputMask if only ! are present in the Progress
Format Expression like "!(4)" is implemented.
FormatHelper:ToInputMask("INTEGER", "HH:MM:SS.SSS+HH:MM")
The Time Mask when passed as an INTEGER is not analysed so H, M and S
will be replaced by n but the Mask will not be validated in any way.
For Time input only a Mask like "HH:MM:SSSS" without a dot within the
seconds and maximum four second placeholders is valid. The Timezone is
not supported by Infragistics.
Purpose: Protected default constructor.
Notes: There's no need to create instances of the helper classes
