Vertical Alignment with Flex Display

In most cases, the vertical alignment of content within FlexGrid cells doesn't matter, since cells contain only a single row of content. However, in some situations you may want to control the vertical alignment of some or all cells. For example, when showing wrapping text or merging cells vertically.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import * as wjGrid from '@grapecity/wijmo.grid'; import { getData } from './data'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // // column properties var theGrid = new wjGrid.FlexGrid('#theGrid', { autoGenerateColumns: false, columns: [ { binding: 'id', header: 'ID', width: 50 }, { binding: 'country', header: 'Country', }, { binding: 'product', header: 'Product', }, { binding: 'sales', header: 'Sales', format: 'c0' }, { binding: 'expenses', header: 'Expenses', format: 'c0' }, { binding: 'active', header: 'Active' } ], itemsSource: getData(), // // use formatItem to apply flex display to the cells // NOTE we could use a CSS rule for this, but we need // formatItem to justify horizontally anyway formatItem: function (s, e) { var style = e.cell.style; style.display = 'flex'; style.alignItems = 'center'; // vertical alignment switch (style.textAlign) { // horizontal alighment case 'right': style.justifyContent = 'flex-end'; break; case 'center': style.justifyContent = 'center'; break; default: style.justifyContent = ''; break; } } }); // // make rows taller to show the vertical alignment theGrid.rows.defaultSize = 45; theGrid.columnHeaders.rows.defaultSize = 65; theGrid.allowResizing = wjGrid.AllowResizing.Both; theGrid.deferResizing = true; }
