Excel Cell Customization

Documentation

The DataGrid allows you to customize data when exporting it to an Excel file: adjust the font options, specify a cell’s background, modify exported values or specify their alignment and formatting options. In this demo, orders before "March 3, 2014" are displayed gray, and the background of 'Sale Amount' cells with a value greater than 15000 is orange. Click the Export button to see how it looks in Excel.
