Methods

This section describes the methods that can be used to manipulate the PivotGrid widget.

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.

TypeScript
import PivotGrid from 'devextreme/ui/pivot_grid';
// ...
export class AppComponent {
    constructor () {
        PivotGrid.defaultOptions({
            device: { deviceType: "desktop" },
            options: {

            }
        });
    }
}

$("#myPivotGrid").remove();
Angular
HTML
<dx-pivot-grid #pivotGridVar id="myPivotGrid"></dx-pivot-grid>
TypeScript
import { ..., ViewChild } from "@angular/core";
import { DxPivotGridComponent } from "devextreme-angular";
// ...
export class AppComponent {
    @ViewChild("pivotGridVar") pivotGrid: DxPivotGridComponent;

        this.pivotGrid.instance.dispose();
        document.getElementById("myPivotGrid").remove();
    }
}
