Description

Out of the box, the Telerik for ASP.NET Core TreeList component enables you to export its data to Excel. Under the hood, the Excel export functionality builds a kendo.ooxml.Workbook. Prior to the export itself, you can further modify the file by using the built-in configuration options of the TreeList, such as exporting multiple pages, modifying the name of the Excel file, saving the exported file on the server, and more.

This demo showcases how to enable the Excel export functionality through the Toolbar() configuration option and, also, how to change the name of the Excel file on the server by setting the ProxyURL() and FileName() configuration methods.
