Other than drag and drop, it is possible to move the panels in Dashboard Layout programmatically. This can be achieved using movePanel method. The method is invoked as follows,
movePanel(id, row, col)Where,
Each time a panel’s position is changed(Programmatically or through UI interaction), the Dashboard Layout’s change event will be triggered.
The following sample demonstrates moving a panel programmatically to a new position in the Dashboard Layout’s created event.
import { DashboardLayoutComponent } from '@syncfusion/ej2-react-layouts';
import * as React from 'react';
export default class App extends React.Component<{}, {}> {
private cellSpacing: number[] = [10, 10];
private panels: any = [
{'sizeX': 1, 'sizeY': 1, 'row': 0, 'col': 0, content:'<div class="content">0</div>'},
{'sizeX': 3, 'sizeY': 2, 'row': 0, 'col': 1, content:'<div class="content">1</div>'},
{'sizeX': 1, 'sizeY': 3, 'row': 0, 'col': 4, content:'<div class="content">2</div>'},
{'sizeX': 1, 'sizeY': 1, 'row': 1, 'col': 0, content:'<div class="content">3</div>'},
{'sizeX': 2, 'sizeY': 1, 'row': 2, 'col': 0, content:'<div class="content">4</div>'},
{'sizeX': 1, 'sizeY': 1, 'row': 2, 'col': 2, content:'<div class="content">5</div>'},
{'sizeX': 1, 'sizeY': 1, 'row': 2, 'col': 3, content:'<div class="content">6</div>'}
];

onCreated(args: any) {
// movePanel("id", row, col)
this.dashboardObj.movePanel("layout_0", 1, 0);
}
//Dashboard Layout's change event function
onChange(args: any) {
