Methods

Methods

Static cancelAsync

  • cancelAsync(done?: Object): void

  • Cancels the task started by the FlexGridXlsxConverter.saveAsync method.

    Parameters

    • Optional done: Object

      Callback invoked when the method finishes executing.

    Returns void

Static load

  • Loads a Workbook instance or a Blob object containing xlsx file content to the FlexGrid instance. This method works with JSZip 2.5.

    For example:

    // This sample opens an xlsx file chosen through Open File
// dialog and fills FlexGrid with the content of the first
// sheet.
 
// HTML
<input type="file"
    id="importFile"
    accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
/>
<div id="flexHost"></>
 
// JavaScript
var flexGrid = new wijmo.grid.FlexGrid("#flexHost"),
    importFile = document.getElementById('importFile');
 
importFile.addEventListener('change', function () {
    loadWorkbook();
});
 
function loadWorkbook() {
    var reader,
        file = importFile.files[0];
    if (file) {
        reader = new FileReader();
        reader.onload = function (e) {
            wijmo.grid.xlsx.FlexGridXlsxConverter.load(flexGrid, reader.result,
                { includeColumnHeaders: true });
        };
        reader.readAsArrayBuffer(file);
    }
}

    Parameters

    Returns void

Static loadAsync

  • loadAsync(grid: FlexGrid, workbook: string | ArrayBuffer | Blob | mXlsx.Workbook, options?: IFlexGridXlsxOptions, onLoaded?: Object, onError?: Object): void

  • Asynchronously loads a Workbook or a Blob representing an xlsx file into a FlexGrid.

    This method requires JSZip 3.0.

    Parameters

    • grid: FlexGrid

      FlexGrid that loads the Workbook object.

    • workbook: string | ArrayBuffer | Blob | mXlsx.Workbook

      Workbook, Blob, base-64 string, or ArrayBuffer representing the xlsx file content.

    • Optional options: IFlexGridXlsxOptions

      IFlexGridXlsxOptions object specifying the load options.

    • Optional onLoaded: Object

      Callback invoked when the method finishes executing. The callback provides access to the workbook that was loaded (passed as a parameter to the callback).

    • Optional onError: Object

      Callback invoked when there are errors saving the file. The error is passed as a parameter to the callback.

      For example:

      wijmo.grid.xlsx.FlexGridXlsxConverter.loadAsync(grid, blob, null, function (workbook) {
     // user can access the loaded workbook instance in this callback.
     var app = worksheet.application ;
     ...
}, function (reason) {
     // User can catch the failure reason in this callback.
     console.log('The reason of save failure is ' + reason);
});

    Returns void

Static save

  • Save the FlexGrid instance to the Workbook instance. This method works with JSZip 2.5.

    For example:

    // This sample exports FlexGrid content to an xlsx file.
// click.
 
// HTML
<button
    onclick="saveXlsx('FlexGrid.xlsx')">
    Save
</button>
 
// JavaScript
function saveXlsx(fileName) {
    // Save the flexGrid to xlsx file.
    wijmo.grid.xlsx.FlexGridXlsxConverter.save(flexGrid,
            { includeColumnHeaders: true }, fileName);
}

    Parameters

    • grid: FlexGrid

      FlexGrid that will be saved.

    • Optional options: IFlexGridXlsxOptions

      IFlexGridXlsxOptions object specifying the save options.

    • Optional fileName: string

      Name of the file that will be generated.

    • Optional batchSize: number

      Batching is done while saving grid rows with excel, this parameter allows customize number of rows per batch.

    Returns mXlsx.Workbook

    A Workbook object that can be used to customize the workbook before saving it (with the Workbook.save method).

Static saveAsync

  • saveAsync(grid: FlexGrid, options?: IFlexGridXlsxOptions, fileName?: string, onSaved?: Object, onError?: Object, onProgress?: Object, asyncWorkbook?: boolean, batchSize?: number): mXlsx.Workbook

  • Asynchronously saves the content of a FlexGrid to a file.

    This method requires JSZip 3.0.

    The return value depends on the {@link asyncWorkbook} parameter. If it is false (default) then the method returns the Workbook instance. If it is true then the method returns a null value and the Workbook instance should be obtained in the {@link onSaved} callback.

    If {@link asyncWorkbook} parameter is true then, once started, the task will be automatically restarted when changes in the grid are detected.

    Parameters

    • grid: FlexGrid

      FlexGrid that will be saved.

    • Optional options: IFlexGridXlsxOptions

      IFlexGridXlsxOptions object specifying the save options.

    • Optional fileName: string

      Name of the file that will be generated.

    • Optional onSaved: Object

      Callback invoked when the method finishes executing. The callback provides access to the content of the saved workbook (encoded as a base-64 string and passed as a parameter to the callback).

    • Optional onError: Object

      Callback invoked when there are errors saving the file. The error is passed as a parameter to the callback.

    • Optional onProgress: Object

      Callback function that gives feedback about the progress of a task. The function accepts a single argument, the current progress as a number between 0 and 100. Can be used only if the {@link asyncWorkbook} parameter is set to true.

    • Optional asyncWorkbook: boolean

      Indicates whether Workbook genaration should be performed asynchronously or not. The default value is false.

    • Optional batchSize: number

      Batching is done while saving grid rows with excel, this parameter allows customize number of rows per batch.

      For example:

      wijmo.grid.xlsx.FlexGridXlsxConverter.saveAsync(flexGrid,
    { includeColumnHeaders: true }, // options
    'FlexGrid.xlsx', // filename
    function (base64) { // onSaved
        // User can access the base64 string in this callback.
        document.getElementByID('export').href = 'data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' + 'base64,' + base64;
    },
    function (reason) { // onError
        // User can catch the failure reason in this callback.
        console.log('The reason of save failure is ' + reason);
    }
 );

    Returns mXlsx.Workbook
