Hi All

Is there a way to prevent input of certain characters in a text field using the input mask or similar function or even through the control description window in Webdev 25?

For example when user inputs data into a text field I do not want the system to accept / < > characters in the text input. It should be possible for the user to enter any other character expect the three characters mentioned above.

Is this possible in Webdev 25?

Hi Gautam,

One simple way is the use of Replace fucntion.

Replace(InitialString, ["<", ">", "//", "/", "\", "\\"], "")
This will replace the special characters you want to block, with none.

I hope to help

Regards
