With List

This demo shows how to filter data in the List using the FilterBuilder component. Note that the DataSource does not support the "between" operation. Call the getFilterExpression() method to convert it into DataSource-compatible operations.

Backend API
$(() => { const currencyFormatter = new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD', minimumFractionDigits: 0, maximumFractionDigits: 0, }); const filterBuilderInstance = $('#filterBuilder').dxFilterBuilder({ fields, value: filter, }).dxFilterBuilder('instance'); $('#listWidget').dxList({ dataSource: new DevExpress.data.DataSource({ store: products, filter: filterBuilderInstance.getFilterExpression(), }), height: '100%', itemTemplate(data) { const result = $('<div>').addClass('product'); $('<img>').attr('src', data.ImageSrc).attr('alt', `Picture of ${data.Name}`).appendTo(result); $('<div>').text(data.Name).appendTo(result); $('<div>').addClass('price') .html(currencyFormatter.format(data.Price)).appendTo(result); return result; }, }); $('#apply').dxButton({ text: 'Apply Filter', type: 'default', onClick() { const filter = filterBuilderInstance.getFilterExpression(); const dataSource = $('#listWidget').dxList('instance').getDataSource(); dataSource.filter(filter); dataSource.load(); }, }); });
