It would be helpful to know the use case, but it sounds like you want the user to only enter number characters with a maximum length of 12. In the "Input String" Control for Brazos UI, there are configuration options called "Input Mask Enabled", and "Input Mask Format". If you enable the first option, you can then fill in your desired pattern in the "Input Mask Format" option. Hovering over the label of this option will show you how to use the patterns.

If the case were, say, exactly 5 number characters, you would write "99999" (without the quotes). If the case were what is described above, up to 12 number characters, you would write "?999999999999" (again, without the quotes).
