How to: Format a Cell or Range of Cells
- 3 minutes to read
Besides using styles that provide the capability to apply a predefined set of format attributes to multiple cells, you can also extend cell formatting with some explicit attributes. To perform direct cell formatting, use the Range object properties that are inherited from the Formatting interface (for example, Formatting.Fill, Formatting.Font, Formatting.Alignment and Formatting.Borders). Initially, these properties are set according to the style applied to the cell.
Thus, the actual cell appearance is determined by the format settings specified by the applied style and the cell’s format settings. Each of these formatting types provides a set of flags (Formatting.Flags). Each flag corresponds to a specific group of format attributes. You can use these flags when formatting a cell, to control whether to use attributes specified in the applied style or attributes specified directly for the cell.
| Group | Attributes | Flag |
|---|---|---|
| Alignment | Horizontal and vertical alignment of cell content, indentation and text wrap. | StyleFlags.Alignment |
| Borders | Cell border line styles and colors. | StyleFlags.Borders |
| Fill | Cell background color. | StyleFlags.Fill |
| Font | Cell font settings (name, style, color and size). | StyleFlags.Font |
| Number Format | Cell number format. | StyleFlags.Number |
| Protection | Cell protection options (Locked and Hidden). | StyleFlags.Protection |
This example demonstrates how to format cells in a worksheet.
- To format an individual cell, access the corresponding Cell object and modify its properties (for example Formatting.Font, Formatting.Fill, Formatting.Borders, Formatting.Alignment and Formatting.NumberFormat).
- To format a range of cells, access and modify the Formatting object via the Range.BeginUpdateFormatting - Range.EndUpdateFormatting paired methods.

A complete sample project is available at https://github.com/DevExpress-Examples/winforms-spreadsheetcontrol-api-e4655
// Access the cell to be formatted.
Cell cell = worksheet.Cells["B2"];
// Specify font settings (font name, color, size and style).
cell.Font.Name = "MV Boli";
cell.Font.Color = Color.Blue;
cell.Font.Size = 14;
cell.Font.FontStyle = SpreadsheetFontStyle.Bold;
// Specify cell background color.
cell.Fill.BackgroundColor = Color.LightSkyBlue;
// Specify text alignment in the cell.
cell.Alignment.Vertical = SpreadsheetVerticalAlignment.Center;
cell.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Center;
// Access the range of cells to be formatted.
Range range = worksheet.Range["C3:E6"];
// Begin updating of the range formatting.
Formatting rangeFormatting = range.BeginUpdateFormatting();
// Specify font settings (font name, color, size and style).
rangeFormatting.Font.Name = "MV Boli";
rangeFormatting.Font.Color = Color.Blue;
rangeFormatting.Font.Size = 14;
rangeFormatting.Font.FontStyle = SpreadsheetFontStyle.Bold;
// Specify cell background color.
rangeFormatting.Fill.BackgroundColor = Color.LightSkyBlue;
// Specify text alignment in cells.
rangeFormatting.Alignment.Vertical = SpreadsheetVerticalAlignment.Center;
rangeFormatting.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Center;
// End updating of the range formatting.
range.EndUpdateFormatting(rangeFormatting);
