JavaScript/jQuery RangeSlider Options
An object defining configuration properties for the RangeSlider UI component.
See Also
accessKey
Specifies the shortcut key that sets focus on the UI component.
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
Specifies whether the UI component changes its visual state as a result of user interaction.
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
disabled
Specifies whether the UI component responds to user interaction.

attribute of the HTML element that underlies the UI component.
validationError
Information on the broken validation rule. Contains the first item from the validationErrors array.
See Also
validationErrors
An array of validation errors.
Array<any>
RangeSlider updates this property automatically as it validates values. You can also update validationErrors manually to display custom errors and implement custom validation logic. The following code snippet demonstrates how to define items in this array:
jQuery
$('#range-slider').dxRangeSlider({ isValid: false, validationErrors: [{ message: "Custom validation error" }], })
Angular
<dx-range-slider [isValid]="false" [validationErrors]="validationErrors" ></dx-range-slider>
import { DxRangeSliderComponent } from 'devextreme-angular/ui/range-slider' export class AppComponent { validationErrors = [ { message: 'Custom validation error' } ]; }
Vue
<script setup lang="ts"> import { DxRangeSlider } from 'devextreme-vue/range-slider'; const validationErrors = [ { message: 'Custom validation error' } ]; </script> <template> <DxRangeSlider :is-valid="false" :validation-errors="validationErrors" /> </template>
React
import { RangeSlider } from 'devextreme-react/range-slider'; const validationErrors = [ { message: 'Custom validation error' } ]; function App(): JSX.Element { return ( <RangeSlider isValid={false} validationErrors={validationErrors} /> ) }
validationMessageMode
Specifies how the message about the validation rules that are not satisfied by this editor's value is displayed.
The following property values are possible:
- auto
The tooltip with the message is displayed when the editor is in focus. - always
The tooltip with the message is not hidden when the editor loses focus.
validationMessagePosition
Specifies the position of a validation message relative to the component. The validation message describes the validation rules that this component's value does not satisfy.
The following example positions a validation message at the component's right:
jQuery
$(function() { $("#rangeSliderContainer").dxRangeSlider({ // ... validationMessagePosition: 'right' }).dxValidator({ validationRules: [{ type: 'required', message: 'Required', }], }); });
Angular
<dx-range-slider ... validationMessagePosition="right"> <dx-validator> <dxi-validation-rule type="required" message="Required" > </dxi-validation-rule> </dx-validator> </dx-range-slider>
Vue
<template> <DxRangeSlider ... validation-message-position="right" > <DxValidator> <DxRequiredRule message="Required" /> </DxValidator> </DxRangeSlider> </template> <script> // ... </script>
React
import React from 'react'; // ... function App() { return ( <RangeSlider ... validationMessagePosition="right" > <Validator> <RequiredRule message="Required" /> </Validator> </RangeSlider> ); }; export default App;
validationStatus
Indicates or specifies the current validation status.
The following table illustrates the validation status indicators:
validationStatus | Indicator |
---|---|
"pending" |
![]() |
"valid" |
![]() |
"invalid" |
![]() |
When you assign "invalid" to validationStatus, you can also use the validationErrors array to set an error message as shown below:
jQuery
$(function() { const rangeSlider = $("#rangeSliderContainer").dxRangeSlider({ // ... }).dxRangeSlider("instance"); function setInvalidStatus(message) { rangeSlider.option({ validationStatus: "invalid", validationErrors: [{ message: message }] }); } });
Angular
<dx-range-slider [validationStatus]="validationStatus" [validationErrors]="validationErrors"> </dx-range-slider>
// ... export class AppComponent { validationStatus: string = "valid"; validationErrors: any; // ... setInvalidStatus(message) { this.validationStatus = "invalid"; this.validationErrors = [{ message: message }]; } }
Vue
<template> <DxRangeSlider ... :validation-status="validationStatus" :validation-errors="validationErrors" /> </template> <script> // ... export default { // ... data() { return { validationStatus: "valid", validationErrors: [] } }, methods: { setInvalidStatus(message) { this.validationStatus = "invalid"; this.validationErrors = [{ message: message }]; } } } </script>
React
import React, { useState } from 'react'; // ... function App() { const [validationStatus, setValidationStatus] = useState("valid"); const [validationErrors, setValidationErrors] = useState([]); const setInvalidStatus = message => { setValidationStatus("invalid"); setValidationErrors([{ message: message }]); } return ( <RangeSlider validationStatus={validationStatus} validationErrors={validationErrors} /> ); }; export default App;
valueChangeMode
Specifies when to change the component's value.
If you want to change the component's value after a user releases the component's handle, set this property to onHandleRelease
. The moment when the onValueChanged function is called depends on this property:
jQuery
$(function() { $("#rangeSliderContainer").dxRangeSlider({ // ... valueChangeMode: 'onHandleRelease', onValueChanged: function (e) { const previousValue = e.previousValue; const newValue = e.value; // Event handling commands go here } }); });
Angular
<dx-range-slider [(value)]="value" valueChangeMode="onHandleRelease" (onValueChanged)="handleValueChange($event)"> </dx-range-slider>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { value = 25; handleValueChange (e) { const previousValue = e.previousValue; const newValue = e.value; // Event handling commands go here }; }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxRangeSliderModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxRangeSliderModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxRangeSlider v-model:value="value" value-change-mode="onHandleRelease" @value-changed="handleValueChange" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxRangeSlider } from 'devextreme-vue/slider'; export default { components: { DxRangeSlider }, data() { return { value: 25 }; }, methods: { handleValueChange(e) { const previousValue = e.previousValue; const newValue = e.value; // Event handling commands go here } } } </script>
React
import React, { useState, useCallback } from 'react'; import 'devextreme/dist/css/dx.light.css'; import { RangeSlider } from 'devextreme-react/range-slider'; function App () { const [value, setValue] = useState(25); const handleValueChange = useCallback((e) => { const previousValue = e.previousValue; const newValue = e.value; // Event handling commands go here setValue(newValue); }, [value]); render() { return ( <RangeSlider value={value} valueChangeMode="onHandleRelease" onValueChanged={handleValueChange} /> ); } } export default App;
width
Specifies the UI component's width.
This property accepts a value of one of the following types:
Number
The width in pixels.String
A CSS-accepted measurement of width. For example,"55px"
,"20vw"
,"80%"
,"auto"
,"inherit"
.
