Printer

The printer can also be seen as an export option, especially since most modern browsers allow users to redirect the output to PDF files, cloud storage, etc. The PrintDocument class makes it easy to create documents for printing. This sample shows how you can convert a FlexGrid into a table element suitable for printing with the PrintDocument class.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import * as wjCore from '@grapecity/wijmo'; import * as wjGrid from '@grapecity/wijmo.grid'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // // render using wijmo.PrintDocument class document.getElementById('btnPrintDoc').addEventListener('click', function (e) { // // create PrintDocument var doc = new wjCore.PrintDocument({ title: 'PrintDocument Test', copyCss: false // prevent cross-origin issues in jsfiddle }); // // add CSS explicitly (since we can't use copyCss in jsfiddle) doc.append('<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">'); doc.append('<link href="https://cdn.grapecity.com/wijmo/5.latest/styles/wijmo.min.css" rel="stylesheet">'); // // add some simple text doc.append('<h1>Printing Example</h1>'); doc.append('<p>This document was created using the <b>PrintDocument</b> class.</p>'); // // add a printer-friendly version of a FlexGrid to the document var flex = wjCore.Control.getControl('#theGrid'); doc.append('<p>Here\'s a FlexGrid rendered as a table:</p>'); var tbl = renderTable(flex); doc.append(tbl); // // print the document doc.print(); }); // // create some random data var countries = 'US,Germany,UK,Japan,Italy,Greece'.split(','), data = []; for (var i = 0; i < 100; i++) { data.push({ id: i, country: countries[i % countries.length], active: i % 5 != 0, downloads: Math.round(Math.random() * 20000), sales: Math.random() * 10000, expenses: Math.random() * 5000 }); } // // show the data in a grid var theGrid = new wjGrid.FlexGrid('#theGrid', { itemsSource: data, }); // // custom grid rendering function: // renders grid as a table function renderTable(flex) { // // start table var tbl = '<table>'; // // headers if (flex.headersVisibility & wjGrid.HeadersVisibility.Column) { tbl += '<thead>'; for (var r = 0; r < flex.columnHeaders.rows.length; r++) { tbl += renderRow(flex.columnHeaders, r); } tbl += '</thead>'; } // // body tbl += '<tbody>'; for (var r = 0; r < flex.rows.length; r++) { tbl += renderRow(flex.cells, r); } tbl += '</tbody>'; // // done tbl += '</table>'; return tbl; } function renderRow(panel, r) { var tr = '', row = panel.rows[r]; if (row.renderSize > 0) { tr += '<tr>'; for (var c = 0; c < panel.columns.length; c++) { var col = panel.columns[c]; if (col.renderSize > 0) { // // get cell style, content var style = 'width:' + col.renderSize + 'px;' + 'text-align:' + col.getAlignment() + ';' + 'padding-right: 6px'; var content = panel.getCellData(r, c, true); if (!row.isContentHtml && !col.isContentHtml) { content = wjCore.escapeHtml(content); } // // add cell to row if (panel.cellType == wjGrid.CellType.ColumnHeader) { tr += '<th style="' + style + '">' + content + '</th>'; } else { // // show boolean values as checkboxes var raw = panel.getCellData(r, c, false); if (raw === true) { content = '&#9745;'; } else if (raw === false) { content = '&#9744;'; } // tr += '<td style="' + style + '">' + content + '</td>'; } } } tr += '</tr>'; } return tr; } }
