Check out all the latest enhancements in the Spreadsheet for Telerik UI for ASP.NET AJAX.
TheR1 2020 SP1 releaseof Telerik UI for ASP.NET AJAX was not only about the PdfViewer control – definitely thestar of the release– but also about the Spreadsheet, which brought to you four highly anticipated features:
- Built-in Import from an Excel File
- Ability to add images
- Out-of-the-box Export to PDF and Excel
- Cell comments
Let me reveal the features one by one plus the benefits for you in more detail:
Import from Excel
This important functionality is now built-in and available at the client-side:
You can make use of it through the fromFile() passing the actual Excel file to the function. For example, the RadAsyncUpload control can be used for selection of a file. In its OnClientFileSelected client-side event, you can get a reference to the selected file and supply the RadSpreadsheet with it:
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1"></telerik:RadSpreadsheet>
<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" OnClientFileSelected="OnClientFileSelected"></telerik:RadAsyncUpload>
<script>
function OnClientFileSelected(sender, args) {
var file = args.get_fileInputField().files[0]; // get the selected file from the RadAsyncUpload
var spreadsheet = $find("<%= RadSpreadsheet1.ClientID %>");
spreadsheet.fromFile(file); //supply the RadSpreadsheet control with the Excel file.
$(args.get_row()).remove(); //remove the row, visualizing the selection in the RadAsyncUpload
}
</script>
Add Images
Right now, you can not only insert images in the sheet via the Insert Image dialog, but also drag and drop them on it for repositioning.
To add the Insert Image button to the toolbar, register the InsertImage tool:
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1">
<Toolbar>
<telerik:SpreadsheetToolbarTab Text="Home">
<telerik:SpreadsheetToolbarGroup>
<telerik:SpreadsheetTool Name="InsertImage" ShowLabel="true" />
</telerik:SpreadsheetToolbarGroup>
</telerik:SpreadsheetToolbarTab>
</Toolbar>
</telerik:RadSpreadsheet>
Tip
If you want, you can delete the image by selecting it and pressing the Delete key.
Export to PDF and Excel
The brand-new ExportAs dialog allows you to export the spreadsheet content to two popular formats: PDF and XLSX.
All you have to do to enable it is to register the ExportAs tool to the toolbar, e.g.
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1">
<Toolbar>
<telerik:SpreadsheetToolbarTab Text="Home">
<telerik:SpreadsheetToolbarGroup>
<telerik:SpreadsheetTool Name="ExportAs" ShowLabel="true" />
</telerik:SpreadsheetToolbarGroup> …
The export to PDF and to Excel can be also triggered programmatically via the API of the underlying Kendo Spreadsheet widget:saveAsPDF andsaveAsExcel.
You can play with the new feature atExport to PDF andExport to Excel File demos.
Cell Comments
The comments feature allows you to insert, edit and remove comments via the provided Insert Comment dialog:
To enable the Insert Comment button add the following entry to the RadSpreadsheet declaration:
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1">
<Toolbar>
<telerik:SpreadsheetToolbarTab Text="Home">
<telerik:SpreadsheetToolbarGroup>
<telerik:SpreadsheetTool Name="InsertComment" ShowLabel="true" />
</telerik:SpreadsheetToolbarGroup>
</telerik:SpreadsheetToolbarTab>
</Toolbar>
</telerik:RadSpreadsheet>
Tips
- You can also add or remove comments via the API of the underlying Kendo widget -range.comment(). Go and test this feature at theCell Comments demo.
- The workbook with Cell Comments can also be imported and exported using the built-in import/export tools.
What’s Next?
- PdfViewer - If you have missed by any chance this super trendy component in the R1 2020 SP1 release, you can take a glance at the Show PDF Files within Your ASP.NET Web Form Page in No Time blog as well as play with thelive demos.
- Timeline – Upcoming in May, another big addition to the R2 release will be the brand-new Timeline component. You will be able to visualize series of events or chronological facts in a stylish and interactive way. It will be a server wrapper of the Kendo UI timeline widget, so if you are curious to learn more about it visitthis link.
