JavaScript/jQuery Data Grid - Paging

The JavaScript DataGrid splits records into multiple pages. This technique helps optimize control performance: the client only needs to load and render one page at a time. Users can use a scroll bar or a pager to navigate between pages. This demo shows how to enable and customize the pager.

Backend API
$(() => { const dataGrid = $('#gridContainer').dxDataGrid({ dataSource: generateData(100000), keyExpr: 'id', showBorders: true, customizeColumns(columns) { columns[0].width = 70; }, scrolling: { rowRenderingMode: 'virtual', }, paging: { pageSize: 10, }, pager: { visible: true, allowedPageSizes: [5, 10, 'all'], showPageSizeSelector: true, showInfo: true, showNavigationButtons: true, }, }).dxDataGrid('instance'); $('#displayMode').dxSelectBox({ items: [{ text: "Display Mode 'full'", value: 'full' }, { text: "Display Mode 'compact'", value: 'compact' }], displayExpr: 'text', inputAttr: { 'aria-label': 'Display Mode' }, valueExpr: 'value', value: 'full', onValueChanged(data) { dataGrid.option('pager.displayMode', data.value); navButtons.option('disabled', data.value === 'compact'); }, }); $('#showPageSizes').dxCheckBox({ text: 'Show Page Size Selector', value: true, onValueChanged(data) { dataGrid.option('pager.showPageSizeSelector', data.value); }, }); $('#showInfo').dxCheckBox({ text: 'Show Info Text', value: true, onValueChanged(data) { dataGrid.option('pager.showInfo', data.value); }, }).dxCheckBox('instance'); const navButtons = $('#showNavButtons').dxCheckBox({ text: 'Show Navigation Buttons', value: true, onValueChanged(data) { dataGrid.option('pager.showNavigationButtons', data.value); }, }).dxCheckBox('instance'); });

let s = 123456789; function random() { s = (1103515245 * s + 12345) % 2147483647; return s % (10 - 1); } function generateData(count) { let i; const surnames = ['Smith', 'Johnson', 'Brown', 'Taylor', 'Anderson', 'Harris', 'Clark', 'Allen', 'Scott', 'Carter']; const names = ['James', 'John', 'Robert', 'Christopher', 'George', 'Mary', 'Nancy', 'Sandra', 'Michelle', 'Betty']; const gender = ['Male', 'Female']; const items = []; const startBirthDate = Date.parse('1/1/1975'); const endBirthDate = Date.parse('1/1/1992'); for (i = 0; i < count; i += 1) { const birthDate = new Date(startBirthDate + Math.floor( (random() * (endBirthDate - startBirthDate)) / 10, )); birthDate.setHours(12); const nameIndex = random(); const item = { id: i + 1, firstName: names[nameIndex], lastName: surnames[random()], gender: gender[Math.floor(nameIndex / 5)], birthDate, }; items.push(item); } return items; }

The pager is configured in the pager object and contains the following elements:

  • Page navigator
    Enables page navigation.

  • Page size selector
    Changes the page size. To display this element, enable the showPageSizeSelector property. You can also define the allowedPageSizes and specify the initial pageSize in the paging object.

  • Page information
    Displays the current page number and total record count. To display page information, enable the showInfo property. You can also use the infoText property to customize the information text string.

The pager supports full, compact, and adaptive (default) display modes. In compact mode, the pager changes the appearance of the page navigator and page selector to use screen space more efficiently. In adaptive mode, the pager automatically chooses between the full and compact modes based on the JavaScript DataGrid's width. Use the displayMode property to switch between modes.

In this demo, you can use the drop-down Display Mode menu to switch between full and compact display modes. You can also use the checkboxes to hide or display different pager elements. Note that when the pager is in compact mode, navigation buttons are always visible.

You can navigate between pages using the on-screen pager controls. Jump to the first/last row of each page by focusing on the data area and using Ctrl+Home or Ctrl+End. These shortcuts focus the first cell of the first row/last cell of the last row.
