It seems that using “input mask” control will result in textbox field being disabled (cannot key in anything) in web view mode. So any other ideas how can to control user inputs?

If you change the @! to !!!!!! (the number of characters allowed) that works.

When using the @ functions the length of the field needs to be known and if there is no control source bound to it it does not know.


allowing only numbers? I tried “999” to no success.


Try @F

Even maxlength,maxdecimals,minvalue,maxvalue can be specified:


Some input masks are not supported in web/mobile client yet

More info:…wers-Inputmask

[EDIT] Sorry, my example works only in desktop. Stick with pure @F


@F10,0 and that will work in all clients.
