Native Components / Inputs / NumericTextBox

Getting Started with KendoVue NumericTextBox

The KendoVue NumericTextBox lets the user edit and submit specific numeric values by typing or by using the spin buttons.

The KendoVue NumericTextBox component is part of the KendoVue library of Vue UI components. It is distributed through NPM under the kendo-vue-inputs package.

Basic Usage

The following example demonstrates the NumericTextBox in action.

<div id="vueapp" class="vue-app">
    <div>
        <label>
            <numerictextbox
                :placeholder="'please enter value'"
                v-model="value"
            >
            </numerictextbox> Kilometers
        </label>
        <br />
        <label>
            <numerictextbox
                :placeholder="'please enter value'"
                :value="computedValue"
                @change="ChangeMiles"
            >
            </numerictextbox> Miles
        </label>
    </div>
</div>
import { NumericTextBox } from '@progress/kendo-vue-inputs';

Vue.component('numerictextbox', NumericTextBox);

new Vue({
    el: '#vueapp',
    computed: {
        computedValue: function(){
            return this.value == null ? null : this.value / 1.609344;
        }
    },
    data: function(){
        return {
            value: null
        };
    },
    methods: {
         ChangeMiles(e) {
            this.value = e.value !== null ? e.value * 1.609344 : null;
        }
    }
});

Functionality and Features

Known Limitations

To keep its value, the NumericTextBox uses the Number JavaScript object. The Number JavaScript object persists its precision up to 16 digits, and units which are longer than that get converted to exponential numbers and lose their precision. Because the component relies on Number, it inherits the precision limitation and because the limitation is caused by the JavaScript logic, the NumericTextBox does not provide a workaround to handle it.
