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

dispose()
The following code disposes of an CircularGauge instance that corresponds to the element ID (or reference variable in Angular) and removes the element from the DOM:
jQuery
$("#myCircularGauge").dxCircularGauge("dispose"); $("#myCircularGauge").remove();
Angular
<dx-circular-gauge #circularGaugeVar id="myCircularGauge"></dx-circular-gauge>
import { ..., ViewChild } from "@angular/core"; import { DxCircularGaugeComponent } from "devextreme-angular"; // ... export class AppComponent { @ViewChild("circularGaugeVar") circularGauge: DxCircularGaugeComponent; removeCircularGauge (e) { this.circularGauge.instance.dispose(); document.getElementById("myCircularGauge").remove(); } }
endUpdate()
Refreshes the widget after a call of the beginUpdate() method.

ID:
// Modular approach import CircularGauge from 'devextreme/viz/circular_gauge'; ... let element = document.getElementById("myCircularGauge"); let instance = CircularGauge.getInstance(element) as CircularGauge; // Non-modular approach let element = document.getElementById("myCircularGauge"); let instance = DevExpress.viz.dxCircularGauge.getInstance(element);
