Open and Save in ASP.NET MVC Spreadsheet control

20 Jan 2022 / 5 minutes to read

To import an excel file, it needs to be read and converted to client side Spreadsheet model. The converted client side Spreadsheet model is sent as JSON which is used to render Spreadsheet. Similarly, when you save the Spreadsheet, the client Spreadsheet model is sent to the server as JSON for processing and saved. Server configuration is used for this process.

Open

The Spreadsheet component opens an Excel document with its data, style, format, and more. To enable this feature, set allowOpen as true and assign service url to the openUrl property.

User Interface:

In user interface you can open an Excel document by clicking File > Open menu item in ribbon.

The following sample shows the Open option by using the openUrl property in the Spreadsheet control. You can also use the beforeOpen event to trigger before opening an Excel file.

razor

opencontroller.cs

@Html.EJS().Spreadsheet("spreadsheet").OpenUrl("Open").AllowOpen(true).BeforeOpen("beforeOpen").Render()

<script>

    function beforeOpen(args) {
        // your code snippets here
    }

</script>

public IActionResult Open(IFormCollection openRequest)
{
    OpenRequest open = new OpenRequest();
    open.File = openRequest.Files[0];
    return Content(Workbook.Open(open));
}

Please find the below table for the beforeOpen event arguments.

Parameter	Type	Description
file	FileList or string or File	To get the file stream. `FileList` - contains length and item index. `File` - specifies the file lastModified and file name.
cancel	boolean	To prevent the open operation.
requestData	object	To provide the Form data.

Use Ctrl + O keyboard shortcut to open Excel documents.

The default value of the allowOpen property is true. For demonstration purpose, we have showcased the allowOpen property in previous code snippet.

Open an external URL excel file while initial load

You can achieve to access the remote excel file by using the created event. In this event you can fetch the excel file and convert it to a blob. Convert this blob to a file and open this file by using Spreadsheet component open method.

razor

opencontroller.cs

@Html.EJS().Spreadsheet("spreadsheet").OpenUrl("Open").AllowOpen(true).Created("created").Render()

<script>

    function created() {
        var spreadsheet = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
        fetch("https://js.syncfusion.com/demos/ejservices/data/Spreadsheet/LargeData.xlsx") // fetch the remote url
            .then((response) => {
                response.blob().then((fileBlob) => { // convert the excel file to blob
                    var file = new File([fileBlob], "Sample.xlsx"); //convert the blob into file
                    spreadsheet.open({ file: file }); // open the file into Spreadsheet
                })
            })
    }

</script>

public IActionResult Open(IFormCollection openRequest)
{
    OpenRequest open = new OpenRequest();
    open.File = openRequest.Files[0];
    return Content(Workbook.Open(open));
}

The default value of allowSave property is true. For demonstration purpose, we have showcased the allowSave property in previous code snippet.

Demo purpose only, we have used the online web service url link.

To send and receive custom params from client to server

Passing the custom parameters from client to server by using beforeSave event.

razor

customParamsController.cs

@Html.EJS().Spreadsheet("spreadsheet").SaveUrl("Save").AllowSave(true).BeforeSave("beforeSave").Sheets((sheet) =>
{
    sheet.Ranges((ranges) =>
    {
        ranges.DataSource(@ViewBag.DefaultData).Add();
    }).Add();
}).Render()

<script>

    function beforeSave(args) {
        args.customParams = { customParams: 'you can pass custom params in server side' }; // you can pass the custom params
    }

</script>
