列ヘッダーのカスタマイズ

デフォルトでは、MultiRowコントロールは列ヘッダーとセルデータに同じlayoutDefinitionを使用します。

headerLayoutDefinitionプロパティを使用して、列ヘッダーのレイアウトをカスタマイズできます。

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import { MultiRow } from '@grapecity/wijmo.grid.multirow'; import { getData, getLayoutDefinition, getHeaderLayoutDefinition } from './data'; document.readyState === 'complete' ? init() : window.onload = init; function init() { // create the MultiRow let theMultiRow = new MultiRow('#theMultiRow', { layoutDefinition: getLayoutDefinition(), headerLayoutDefinition: getHeaderLayoutDefinition(), itemsSource: getData() }); // toggle custom header layout document.getElementById('cbCustomHeaders').addEventListener('click', function (e) { theMultiRow.headerLayoutDefinition = e.target.checked ? getHeaderLayoutDefinition() : null; }); }
