Maintain trailing zeros in numerictextbox in EJ2 TypeScript Numerictextbox control

15 May 20233 minutes to read

By default, trailing zeros disappear when the NumericTextBox gets focus. However, you can use the following sample to maintain the trailing zeros while focusing the NumericTextBox.

import {NumericTextBox} from '@syncfusion/ej2-inputs';
//maintains trailing zeros while focusing
let numericFocus: function () {
    var numericObj = this.ej2_instances ? this.ej2_instances[0] : this;
    numericObj.element.value = numericObj.formattedValue(numericObj.decimals, +numericObj.element.value);
// Render the Numeric Textbox
let numeric: NumericTextBox = new NumericTextBox({
    value: 10,
    format: 'n2',
    placeholder: 'NumericTextbox',
    floatLabelType: 'Always' ,
    change: numericFocus
document.getElementById('numeric').addEventListener('focus', numericFocus);
