User Interaction
An end user can scroll the ScrollView content with the swipe gesture or with the scrollbar. The swipe gesture is default for touch devices, the scrollbar is default for desktops. However, you can unify the behavior of the ScrollView on all platforms. To control the swipe gesture scrolling, use the scrollByContent property. To control the scrollbar scrolling, use the scrollByThumb property.
jQuery
$(function() { $("#scrollViewContainer").dxScrollView({ scrollByContent: true, // enables the swipe gesture on all platforms scrollByThumb: true // makes the scrollbar active on all platforms }); });
<div id="scrollViewContainer"></div>
Angular
<dx-scroll-view [scrollByContent]="true" <!-- enables the swipe gesture on all platforms --> [scrollByThumb]="true"> <!-- makes the scrollbar active on all platforms --> </dx-scroll-view>
import { DxScrollViewModule } from 'devextreme-angular'; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxScrollViewModule ], // ... })
Vue
<template> <DxScrollView :scroll-by-content="true" <!-- enables the swipe gesture on all platforms --> :scroll-by-thumb="true" <!-- makes the scrollbar active on all platforms --> /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxScrollView } from 'devextreme-vue/scroll-view'; export default { components: { DxScrollView } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { ScrollView } from 'devextreme-react/scroll-view'; class App extends React.Component { render() { return ( <ScrollView scrollByContent={true} {/* enables the swipe gesture on all platforms */} scrollByThumb={true} {/* makes the scrollbar active on all platforms */} /> ); } } export default App;
API
To scroll through ScrollView content by a specified distance, call the scrollBy(distance) method and pass a Number
as a parameter. If you need to scroll in the opposite direction, the distance
parameter should be a negative number.
jQuery
$(function() { var scrollView = $("#scrollViewContainer").dxScrollView({ height: 200 }).dxScrollView("instance"); $("#scrollUpButton").dxButton({ text: "Scroll Up", onClick: function() { scrollView.scrollBy(-100); } }); $("#scrollDownButton").dxButton({ text: "Scroll Down", onClick: function() { scrollView.scrollBy(100); } }); });
<div id="scrollUpButton"></div> <div id="scrollDownButton"></div> <div id="scrollViewContainer">Content</div>
Angular
<dx-button text="Scroll Up" (onClick)="scrollUp()"> </dx-button> <dx-button text="Scroll Down" (onClick)="scrollDown()"> </dx-button> <dx-scroll-view [height]="200"> <div>Content</div> </dx-scroll-view>
import { ..., ViewChild } from '@angular/core'; import { DxScrollViewModule, DxScrollViewComponent, DxButtonModule } from 'devextreme-angular'; // ... export class AppComponent { @ViewChild(DxScrollViewComponent, { static: false }) scrollView: DxScrollViewComponent; // Prior to Angular 8 // @ViewChild(DxScrollViewComponent) scrollView: DxScrollViewComponent; scrollUp() { this.scrollView.instance.scrollBy(-100); } scrollDown() { this.scrollView.instance.scrollBy(100); } } @NgModule({ imports: [ // ... DxScrollViewModule, DxButtonModule ], // ... })
Vue
<template> <div> <DxButton text="Scroll Up" @click="scrollUp"> </DxButton> <DxButton text="Scroll Down" @click="scrollDown"> </DxButton> <DxScrollView :ref="myScrollViewRef" :height="200"> <div>Content</div> </DxScrollView> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxButton } from 'devextreme-vue'; import { DxScrollView } from 'devextreme-vue/scroll-view'; const myScrollViewRef = 'my-scroll-view'; export default { components: { DxButton, DxScrollView }, data() { return { myScrollViewRef } }, methods: { scrollUp() { this.scrollView.scrollBy(-100); } scrollDown() { this.scrollView.scrollBy(100); } }, computed: { scrollView: function() { return this.$refs[myScrollViewRef].instance; } } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Button } from 'devextreme-react'; import { ScrollView } from 'devextreme-react/scroll-view'; class App extends React.Component { constructor(props) { super(props); this.scrollViewRef = React.createRef(); } get scrollView() { return this.scrollViewRef.current.instance; } render() { return ( <Button text="Scroll Up" onClick={this.scrollUp}> </Button> <Button text="Scroll Down" onClick={this.scrollDown}> </Button> <ScrollView ref={this.scrollViewRef} height={200}> <div>Content</div> </ScrollView> ); } scrollUp = () => { this.scrollView.scrollBy(-100); } scrollDown = () => { this.scrollView.scrollBy(100); } } export default App;
To scroll content vertically and horizontally, call the scrollBy(distance) method with an object as an argument. The format of the object is the following: { left: value1, top: value2 }. In this case, set the direction property to "both":
jQuery
$(function() { var scrollView = $("#scrollViewContainer").dxScrollView({ height: 200, width: 100, direction: "both" }).dxScrollView("instance"); $("#scrollButton").dxButton({ text: "Scroll", onClick: function() { scrollView.scrollBy({ left: 100, top: 100 }); } }); });
<div id="scrollButton"></div> <div id="scrollViewContainer">Content</div>
Angular
<dx-button text="Scroll" (onClick)="scroll()"> </dx-button> <dx-scroll-view [height]="200" [width]="100" direction="both"> <div>Content</div> </dx-scroll-view>
import { ..., ViewChild } from '@angular/core'; import { DxScrollViewModule, DxScrollViewComponent, DxButtonModule } from 'devextreme-angular'; // ... export class AppComponent { @ViewChild(DxScrollViewComponent, { static: false }) scrollView: DxScrollViewComponent; // Prior to Angular 8 // @ViewChild(DxScrollViewComponent) scrollView: DxScrollViewComponent; scroll() { this.scrollView.instance.scrollBy({ left: 100, top: 100 }); } } @NgModule({ imports: [ // ... DxScrollViewModule, DxButtonModule ], // ... })
Vue
<template> <div> <DxButton text="Scroll" @click="scroll"> </DxButton> <DxScrollView :ref="myScrollViewRef" :height="200" :width="100" direction="both"> <div>Content</div> </DxScrollView> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxButton } from 'devextreme-vue'; import { DxScrollView } from 'devextreme-vue/scroll-view'; const myScrollViewRef = 'my-scroll-view'; export default { components: { DxButton, DxScrollView }, data() { return { myScrollViewRef } }, methods: { scroll() { this.scrollView.scrollBy({ left: 100, top: 100 }); } }, computed: { scrollView: function() { return this.$refs[myScrollViewRef].instance; } } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Button } from 'devextreme-react'; import { ScrollView } from 'devextreme-react/scroll-view'; class App extends React.Component { constructor(props) { super(props); this.scrollViewRef = React.createRef(); } get scrollView() { return this.scrollViewRef.current.instance; } render() { return ( <Button text="Scroll" onClick={this.scroll}> </Button> <ScrollView ref={this.scrollViewRef} height={200} width={100} direction="both"> <div>Content</div> </ScrollView> ); } scroll = () => { this.scrollView.scrollBy({ left: 100, top: 100 }); } } export default App;
To scroll the content to a specific position, call the scrollTo(targetLocation) method. Just like the scrollBy() method from the previous examples, the scrollTo() method accepts either a numeric value (when directon is "left" or "right") or an object (when direction is "both"). The object should have the following format: { left: value1, top: value2 }. Note that the top left corner of the ScrollView has the { left: 0, top: 0 } coordinates.
jQuery
$(function() { var scrollView = $("#scrollViewContainer").dxScrollView({ height: 200, width: 100, direction: "vertical" }).dxScrollView("instance"); $("#scrollButton").dxButton({ text: "Scroll", onClick: function() { scrollView.scrollTo(300); } }); });
<div id="scrollButton"></div> <div id="scrollViewContainer">Content</div>
Angular
<dx-button text="Scroll" (onClick)="scroll()"> </dx-button> <dx-scroll-view [height]="200" [width]="100" direction="vertical"> <div>Content</div> </dx-scroll-view>
import { ..., ViewChild } from '@angular/core'; import { DxScrollViewModule, DxScrollViewComponent, DxButtonModule } from 'devextreme-angular'; // ... export class AppComponent { @ViewChild(DxScrollViewComponent, { static: false }) scrollView: DxScrollViewComponent; // Prior to Angular 8 // @ViewChild(DxScrollViewComponent) scrollView: DxScrollViewComponent; scroll() { this.scrollView.instance.scrollTo(300); } } @NgModule({ imports: [ // ... DxScrollViewModule, DxButtonModule ], // ... })
Vue
<template> <div> <DxButton text="Scroll" @click="scroll"> </DxButton> <DxScrollView :ref="myScrollViewRef" :height="200" :width="100" direction="vertical"> <div>Content</div> </DxScrollView> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxButton } from 'devextreme-vue'; import { DxScrollView } from 'devextreme-vue/scroll-view'; const myScrollViewRef = 'my-scroll-view'; export default { components: { DxButton, DxScrollView }, data() { return { myScrollViewRef } }, methods: { scroll() { this.scrollView.scrollTo(300); } }, computed: { scrollView: function() { return this.$refs[myScrollViewRef].instance; } } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Button } from 'devextreme-react'; import { ScrollView } from 'devextreme-react/scroll-view'; class App extends React.Component { constructor(props) { super(props); this.scrollViewRef = React.createRef(); } get scrollView() { return this.scrollViewRef.current.instance; } render() { return ( <Button text="Scroll" onClick={this.scroll}> </Button> <ScrollView ref={this.scrollViewRef} height={200} width={100} direction="vertical"> <div>Content</div> </ScrollView> ); } scroll = () => { this.scrollView.scrollTo(300); } } export default App;
To scroll content to a specific element, call the scrollToElement(element) method.
jQuery
<div id="scrollButton"></div> <div id="scrollViewContainer"> <!-- Here goes long content --> <div id="end"></div> </div>
$(function() { var scrollView = $("#scrollViewContainer").dxScrollView({ height: 200, width: 100, direction: "vertical" }).dxScrollView("instance"); $("#scrollButton").dxButton({ text: "Scroll", onClick: function() { // Scrolls the content to the element with the "end" id scrollView.scrollToElement($("#end")); } }); });
Angular
<dx-button text="Scroll" (onClick)="scroll()"> </dx-button> <dx-scroll-view [height]="200" [width]="100" direction="vertical"> <!-- Here goes long content --> <div id="end"></div> </dx-scroll-view>
import { ..., ViewChild } from '@angular/core'; import { DxScrollViewModule, DxScrollViewComponent, DxButtonModule } from 'devextreme-angular'; // ... export class AppComponent { @ViewChild(DxScrollViewComponent, { static: false }) scrollView: DxScrollViewComponent; // Prior to Angular 8 // @ViewChild(DxScrollViewComponent) scrollView: DxScrollViewComponent; scroll() { // Scrolls the content to the element with the "end" id this.scrollView.instance.scrollToElement(document.querySelector('#end')); } } @NgModule({ imports: [ // ... DxScrollViewModule, DxButtonModule ], // ... })
Vue
<template> <div> <DxButton text="Scroll" @click="scroll"> </DxButton> <DxScrollView :ref="myScrollViewRef" :height="200" :width="100" direction="vertical"> <!-- Here goes long content --> <div id="end"></div> </DxScrollView> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxButton } from 'devextreme-vue'; import { DxScrollView } from 'devextreme-vue/scroll-view'; const myScrollViewRef = 'my-scroll-view'; export default { components: { DxButton, DxScrollView }, data() { return { myScrollViewRef } }, methods: { scroll() { // Scrolls the content to the element with the "end" id this.scrollView.scrollToElement(document.querySelector('#end')); } }, computed: { scrollView: function() { return this.$refs[myScrollViewRef].instance; } } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Button } from 'devextreme-react'; import { ScrollView } from 'devextreme-react/scroll-view'; class App extends React.Component { constructor(props) { super(props); this.scrollViewRef = React.createRef(); } get scrollView() { return this.scrollViewRef.current.instance; } render() { return ( <Button text="Scroll" onClick={this.scroll}> </Button> <ScrollView ref={this.scrollViewRef} height={200} width={100} direction="vertical"> {/* Here goes long content */} <div id="end"></div> </ScrollView> ); } scroll = () => { // Scrolls the content to the element with the "end" id this.scrollView.scrollToElement(document.querySelector('#end')); } } export default App;
To get the current scroll position against the top left corner, call the scrollOffset() method. It returns an object of the following format: { top: topScrollOffset, left: leftScrollOffset }. If you need to get only the top or left scroll offset, use the scrollTop() and scrollLeft() methods, respectively.
