How to limit the number of input(Number) in a text box.

I am using Outsystems 10 and limit the number of input user give in text box by 29 digits.

Use the input's "Max. Length" property.

Thanks a lot, Max. Length option is coming when the input type is text but not when input type is number.

Hi, Pratik

You could use the text input with the max length property and a jscript running onKeyDown blocking anything that's not a number. Something like this could work:

function PreventAlphabet() {
    var key = event.which || eventkeyCode
   
    if(key > 64 && key < 91){
        event.preventDefault();
    }
};

What it's doing is preventing the insertion of characters from A to Z and a to z, using their unicodes.
