Hello

You can refer to the Solution here.

You need to do that by using Regex Pattern to restrict user to input only number.

Let me know if this will help

Thanks

Hi Nayan,

Note that the reason for e/E and + (and -) to be allowed is for scientific notation of numbers, e.g. 1.23e+01. So it's not just some random characters that are allowed.

You can achive this with JS to prevent letters etc.

Put this on your OnReady:

function isControlKeyCode(keyCode) {

    var backspace = 8, tab = 9, enter = 13, shift = 16, ctrl = 17, alt = 18, pauseBreak = 19, capsLock = 20, escape = 27, space = 32, pageUp = 33, pageDown = 34, end = 35, home = 36, leftArrow = 37, upArrow = 38, rightArrow = 39, downArrow = 40, insert = 45, del = 46;

    var arrControlKeys = [ backspace, tab, enter, shift, ctrl, alt, pauseBreak, capsLock, escape, pageUp, pageDown, end, home, leftArrow, upArrow, rightArrow, downArrow, insert, del ];

    return arrControlKeys.indexOf(keyCode) > -1;

}

function restrictCharacter(regExPermitedCharacters, event) {

    var ok = true;

    var key = event.charCode || event.keyCode;

    if (!isControlKeyCode(key)) {

        ok = regExPermitedCharacters.test(String.fromCharCode(key));

    }

    if (!ok && !event.ctrlKey) {

        event.preventDefault();

        return false;

    }

}

var pattern = /^-?[0-9]+$/;

document.getElementById($parameters.WidgetId).addEventListener("keypress", function(e){

    restrictCharacter(new RegExp(pattern), e);

});

Hi @Nayana Sonawane,

You can restrict input to accept only numbers by setting input attribute as:

property: pattern 

value: "[0-9]*"

It's working fine for me.
