jQuery DataGrid - export

Configures client-side exporting.

Type:

Object

A user can click the Export button to save an Excel file with the exported data. Data types, sort, filter, and group settings are maintained.

DevExtreme HTML5 JavaScript DataGrid Export Button

The following instructions show how to enable and configure client-side export:

  1. Install or reference the required libraries
    This feature requires ExcelJS v4+ and FileSaver v2.0.2+.

    jQuery
    HTML
    <head>
        <!-- ... -->
        <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.4.0/polyfill.min.js"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/exceljs/4.1.1/exceljs.min.js"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/2.0.2/FileSaver.min.js"></script>
        <!-- reference the DevExtreme sources here -->
    </head>
    Angular
    Installation command
    tsconfig.app.json
    npm install --save exceljs file-saver
    {
        "compilerOptions": {
            // ...
            "paths": {
                // ...
                "exceljs": [
                    "node_modules/exceljs/dist/exceljs.min.js"
                ]
            }
        }
    }
    Vue
    npm install --save exceljs file-saver
    React
    npm install --save exceljs file-saver
  2. Enable the export UI
    Set the export.enabled property to true. This property enables export for all columns. Set a column's allowExporting property to false to prevent it from being exported:

    jQuery
    JavaScript
    $(function () {
        $("#dataGridContainer").dxDataGrid({
            export: {
                enabled: true
            },
            columns: [{ ...
                allowExporting: false
            }, 
                // ...
            ]
        });
    });

    @Component({
        selector: 'app-root',
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.css']
    })
    export class AppComponent {
        // ...
    }
    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule } from '@angular/core';
    import { AppComponent } from './app.component';
    
    import { DxDataGridModule } from 'devextreme-angular';
    
    @NgModule({
        declarations: [
            AppComponent
        ],
        imports: [
            BrowserModule,
            DxDataGridModule
        ],
        providers: [ ],
        bootstrap: [AppComponent]
    })
    export class AppModule { }
    Vue
    App.vue
    <template>
        <DxDataGrid ... >
            <DxExport
                :enabled="true"
            />
            <DxColumn ... 
                :allow-exporting="false"
            />
        </DxDataGrid>
    </template>
    
    <script>
    import 'devextreme/dist/css/dx.light.css';
    
    import { DxDataGrid, 
        DxExport,
        DxColumn
    } from 'devextreme-vue/data-grid';
    
    export default {
        components: {
            DxDataGrid,
            DxExport,
            DxColumn
        }
    }
    </script>
    React
    App.js
    import React from 'react';
    import 'devextreme/dist/css/dx.light.css';
    
    import DataGrid, {
        Export,
        Column
    } from 'devextreme-react/data-grid';
    
    class App extends React.Component {
        render() {
            return (
                <DataGrid ... >
                    <Export enabled={true} />
                    <Column ...
                        allowExporting={false}
                    />
                </DataGrid>
            );
        }
    }
    export default App;
  3. Export the DataGrid
    Implement the onExporting handler and call the exportDataGrid(options) method in it. In the code below, this method exports the DataGrid as is, but you can use ExcelExportDataGridProps to configure export settings, including cell customization. The DataGrid is exported to an Excel worksheet that is created using the ExcelJS API. To save the Excel document, call the FileSaver's saveAs method. The e.cancel parameter disables the deprecated built-in export implementation with fewer capabilities.

    jQuery
    JavaScript
    $('#gridContainer').dxDataGrid({
        export: {
            enabled: true
        },
        onExporting: function(e) { 
            var workbook = new ExcelJS.Workbook(); 
            var worksheet = workbook.addWorksheet('Main sheet'); 
            DevExpress.excelExporter.exportDataGrid({ 
                worksheet: worksheet, 
                component: e.component,
                customizeCell: function(options) {
                    var excelCell = options;
                    excelCell.font = { name: 'Arial', size: 12 };
                    excelCell.alignment = { horizontal: 'left' };
                } 
            }).then(function() {
                workbook.xlsx.writeBuffer().then(function(buffer) { 
                    saveAs(new Blob([buffer], { type: 'application/octet-stream' }), 'DataGrid.xlsx'); 
                }); 
            }); 
            e.cancel = true; 
        }
    });

excelFilterEnabled Deprecated

Since v20.1, we recommend ExcelJS-based export which does not use this property.

Specifies whether to enable Excel filtering for the exported data in the resulting XLSX file.

Type:

Boolean

Default Value: false

excelWrapTextEnabled Deprecated

Since v20.1, we recommend ExcelJS-based export which does not use this property.

Specifies whether to enable word wrapping for exported data in the resulting XLSX file.

Specifies the URL of the server-side proxy that streams the resulting file to the end user to enable exporting in the Safari browser.

Type:

String

Default Value: undefined

Generally, exporting is performed using client-side API in browsers. However, the Safari (integrated in Mac OS) browser does not implement an API for saving files. In this instance, the DataGrid UI component can POST the content to a server-side proxy, which will stream the file back to the end user. To enable this functionality, set the export.proxyUrl property to the proxy, which will stream the file to the end user. When implementing the proxy, take the following information into account.

  • Your proxy will receive a POST request with the following parameters in the request body: fileName, contentType (the MIME type of the file) and base64 (the base-64 encoded file content).
  • The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="".

Configures the texts of export commands, buttons, and hints.
