Methods
beginUpdate()
Postpones rendering that can negatively affect performance until the endUpdate() method is called.
dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myLinearGauge").dxLinearGauge("dispose");
$("#myLinearGauge").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-linear-gauge ...
*ngIf="condition">
</dx-linear-gauge>Vue
<template>
<DxLinearGauge ...
v-if="condition">
</DxLinearGauge>
</template>
<script>
import DxLinearGauge from 'devextreme-vue/linear-gauge';
export default {
components: {
DxLinearGauge
}
}
</script>React
import React from 'react';
import LinearGauge from 'devextreme-react/linear-gauge';
function DxLinearGauge(props) {
if (!props.shouldRender) {
return null;
}
return (
<LinearGauge ... >
</LinearGauge>
);
}
class App extends React.Component {
render() {
return (
<DxLinearGauge 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 LinearGauge instance found in an element with the myLinearGauge ID:
// Modular approach
import LinearGauge from "devextreme/viz/linear_gauge";
...
let element = document.getElementById("myLinearGauge");
let instance = LinearGauge.getInstance(element) as LinearGauge;
// Non-modular approach
let element = document.getElementById("myLinearGauge");
let instance = DevExpress.viz.dxLinearGauge.getInstance(element);See Also
render()
Normally, the UI component redraws itself automatically after the browser window is resized. But on rare occasions, you may need to request the redrawing, for example, after the UI component's container is resized. For this purpose, call the render() method.
