How to: Load and Use Custom Fonts in the Spreadsheet Control

  • 3 minutes to read

The WPF Spreadsheet control ships with the DXFontRepository class that allows you to use fonts that are not installed on the current operating system. When you load a document that uses such fonts, the Spreadsheet substitutes missing fonts with the fonts available on the current machine. The DXFontRepository class allows you to load and use custom fonts in your application to prevent font substitution when documents are displayed, printed, or exported to PDF.

Use the DXFontRepository.Instance static property to access a DXFontRepository instance.

Add Fonts to the Font Repository

Use the DXFontRepository.AddFont method to add fonts to the font repository. The WPF Spreadsheet control allows you load fonts only from files. Loaded fonts are available to all SpreadsheetControl instances within your project.

Supported font formats include:

  • TrueType fonts (.TTF)

  • OpenType fonts that use CFF (Compact Font Format) glyph outlines (.OTF)

  • OpenType Font Collections (.TTC, .OTC) that contain multiple fonts in a single file

To avoid excessive document layout recalculations, add the required fonts to DXFontRepository before you load a document that uses these fonts.

The code sample below adds the following Google fonts fonts to DXFontRepository and uses these fonts to format cells in a workbook:

using DevExpress.Drawing;
using DevExpress.Spreadsheet;

namespace WpfSpreadsheet
    public partial class MainWindow : DevExpress.Xpf.Core.ThemedWindow
        public MainWindow()

            IWorkbook workbook = spreadsheetControl1.Document;
            workbook.LoadDocument(@"Documents\SalesReport.xlsx", DocumentFormat.Xlsx);

            Worksheet worksheet = workbook.Worksheets["Report"];

            // Return the cell that contains the document title.
            Cell cell = worksheet.Cells["B2"];

            // Specify font settings (font name and size).
            cell.Font.Name = "Advent Pro";
            cell.Font.Size = 26;

            // Return the cell range that contains report data.
            CellRange range = worksheet.Range["B4:F20"];

            // Start range format update. 
            var rangeFormatting = range.BeginUpdateFormatting();
            // Specify font settings (font name and size).
            rangeFormatting.Font.Name = "Roboto Light";
            rangeFormatting.Font.Size = 14;
            // End range format update. 

The following image demonstrates the result:

Document with Custom Fonts

Obtain Information About Fonts in the Repository

Use the DXFontRepository.GetFonts method to return a list of all fonts in the font repository. Each item in this list is a DXFontData object that contains font information.

Clear the Font Repository

Call the DXFontRepository.Clear method to remove all fonts from the font repository. Use the DXFontRepository.IsEmpty property to check whether the repository contains fonts.

using DevExpress.Drawing;
// ...

// Check whether the font repository is empty.
if (!DXFontRepository.Instance.IsEmpty)
    // If false, clear the font repository.


  1. Loaded fonts are not saved to a document. These fonts are used to display the document in the control’s UI, print the document, or export the document to PDF.

  2. Loaded fonts are not displayed in the drop-down list of the Spreadsheet control’s font editor.
