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 Resizable UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxResizable.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the Resizable properties
}
});Angular
import Resizable from "devextreme/ui/resizable";
// ...
export class AppComponent {
constructor () {
Resizable.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the Resizable properties
}
});
}
}Vue
<template>
<div>
<DxResizable id="resizable1" />
<DxResizable id="resizable2" />
</div>
</template>
<script>
import DxResizable from "devextreme-vue/resizable";
import Resizable from "devextreme/ui/resizable";
Resizable.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the Resizable properties
}
});
export default {
components: {
DxResizable
}
}
</script>React
import React, {useEffect} from "react";
import dxResizable from "devextreme/ui/resizable";
import Resizable from "devextreme-react/resizable";
export default function App() {
useEffect(() => {
dxResizable.defaultOptions({
device: { deviceType: "desktop" },
options: {
// Here go the Resizable properties
}
})
});
return (
<div>
<Resizable id="resizable1" />
<Resizable id="resizable2" />
</div>
)
}dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myResizable").dxResizable("dispose");
$("#myResizable").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-resizable ...
*ngIf="condition">
</dx-resizable>Vue
<template>
<DxResizable ...
v-if="condition">
</DxResizable>
</template>
<script>
import DxResizable from 'devextreme-vue/resizable';
export default {
components: {
DxResizable
}
}
</script>React
import React from 'react';
import Resizable from 'devextreme-react/resizable';
function DxResizable(props) {
if (!props.shouldRender) {
return null;
}
return (
<Resizable ... >
</Resizable>
);
}
class App extends React.Component {
render() {
return (
<DxResizable 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 Resizable instance found in an element with the myResizable ID:
// Modular approach
import Resizable from "devextreme/ui/resizable";
...
let element = document.getElementById("myResizable");
let instance = Resizable.getInstance(element) as Resizable;
// Non-modular approach
let element = document.getElementById("myResizable");
let instance = DevExpress.ui.dxResizable.getInstance(element);
