JavaScript/jQuery ResponsiveBox Methods
beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

defaultOptions(rule)
defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the ResponsiveBox UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxResponsiveBox.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the ResponsiveBox properties
}
});Angular
import ResponsiveBox from "devextreme/ui/responsive_box";
// ...
export class AppComponent {
constructor () {
ResponsiveBox.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the ResponsiveBox properties
}
});
}
}Vue
<template>
<div>
<DxResponsiveBox id="responsiveBox1" />
<DxResponsiveBox id="responsiveBox2" />
</div>
</template>
<script>
import DxResponsiveBox from "devextreme-vue/responsive-box";
import ResponsiveBox from "devextreme/ui/responsive_box";
ResponsiveBox.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the ResponsiveBox properties
}
});
export default {
components: {
DxResponsiveBox
}
}
</script>React
import React, {useEffect} from "react";
import dxResponsiveBox from "devextreme/ui/responsive_box";
import ResponsiveBox from "devextreme-react/responsive-box";
export default function App() {
useEffect(() => {
dxResponsiveBox.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the ResponsiveBox properties
}
})
});
return (
<div>
<ResponsiveBox id="responsiveBox1" />
<ResponsiveBox id="responsiveBox2" />
</div>
)
}dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myResponsiveBox").dxResponsiveBox("dispose");
$("#myResponsiveBox").remove();Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-responsive-box ...
*ngIf="condition">
</dx-responsive-box>Vue
<template>
<DxResponsiveBox ...
v-if="condition">
</DxResponsiveBox>
</template>
<script>
import DxResponsiveBox from 'devextreme-vue/responsive-box';
export default {
components: {
DxResponsiveBox
}
}
</script>React
import React from 'react';
import ResponsiveBox from 'devextreme-react/responsive-box';
function DxResponsiveBox(props) {
if (!props.shouldRender) {
return null;
}
return (
<ResponsiveBox ... >
</ResponsiveBox>
);
}
class App extends React.Component {
render() {
return (
<DxResponsiveBox shouldRender="condition" />
);
}
}
export default App;See Also

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the ResponsiveBox instance found in an element with the myResponsiveBox ID:
// Modular approach
import ResponsiveBox from "devextreme/ui/responsive_box";
...
let element = document.getElementById("myResponsiveBox");
let instance = ResponsiveBox.getInstance(element) as ResponsiveBox;
// Non-modular approach
let element = document.getElementById("myResponsiveBox");
let instance = DevExpress.ui.dxResponsiveBox.getInstance(element);
