Does anyone know if you use alpha numeric masking?
I am trying to add a text attribute masking to restrict the number of character, but it needs to allow alpha numeric entry.
Is there a guide somewhere that explains how the masking expressions work?

I am referring to CSAttribute - Configuration > Common Settings > Attributes
For CSAttribute of Text type you can assign an Entry Mask and Reg. Exp. (Regular Expression)
For my use case, I am using an input validation for an attribute we created for VIN (Vehicle Identification Number).
VINs are 17 characters long alpha numeric, all upper case. Thus, I did the following:
Entry Mask: >CCCCCCCCCCCCCCCCC
From what I understand, the entry mask is just that, it creates a mask. This expression creates a mask that allows any character (C) auto corrects to upper case (>) and allows up to 17 characters.
Reg. Exp.: >CCCCCCCCCCCCCCCCC{17,17}
This expression validates if the input was 17 characters long {17,17}, is uppercase and is any character.
I have never used Regular Expression before so this took some tinkering for me to figure out the correct syntax. https://learn.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/ae5bf541(v=vs.100)?redirectedfrom=MSDN
Thank you for sharing where you found the information
It is possible to specify the regular expression in the input mask value in PXUIField Attribute?
