React TreeMap 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 TreeMap instance that corresponds to the element ID (or reference variable in Angular) and removes the element from the DOM:
jQuery
$("#myTreeMap").dxTreeMap("dispose"); $("#myTreeMap").remove();
Angular
<dx-tree-map #treeMapVar id="myTreeMap"></dx-tree-map>
import { ..., ViewChild } from "@angular/core"; import { DxTreeMapComponent } from "devextreme-angular"; // ... export class AppComponent { @ViewChild("treeMapVar") treeMap: DxTreeMapComponent; removeTreeMap (e) { this.treeMap.instance.dispose(); document.getElementById("myTreeMap").remove(); } }
drillUp()
To learn how to implement the drill down functionality, see the drillDown() method description.
endUpdate()
Refreshes the widget after a call of the beginUpdate() method.

getInstance(element)
getInstance is a static method that the widget class supports. The following code demonstrates how to get the TreeMap instance found in an element with the myTreeMap
ID:
// Modular approach import TreeMap from "devextreme/viz/tree_map"; ... let element = document.getElementById("myTreeMap"); let instance = TreeMap.getInstance(element) as TreeMap; // Non-modular approach let element = document.getElementById("myTreeMap"); let instance = DevExpress.viz.dxTreeMap.getInstance(element);

render()
Normally, the widget redraws itself automatically after the browser window is resized. But on rare occasions, you may need to request the redrawing, for example, after the widget's container is resized. For this purpose, call the render() method.

resetDrillDown()
Calling this method makes the root level the current one. If you need to drill one level up or down, use the drillUp() method of the widget or the drillDown() method of a node.
