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.

dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myGantt").dxGantt("dispose"); $("#myGantt").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-gantt ... *ngIf="condition"> </dx-gantt>
Vue
<template> <DxGantt ... v-if="condition"> </DxGantt> </template> <script> import DxGantt from 'devextreme-vue/gantt'; export default { components: { DxGantt } } </script>
