To specify the characteristics of cell diagonal borders, use the DiagonalBorderLineStyle , Borders.DiagonalBorderColor and Borders.DiagonalBorderType properties.
If you specify the type and color of the diagonal border without setting it’s line style, the DiagonalBorderLineStyle property will be automatically set to BorderLineStyle.Thin.
If you set a color and line style of a cell diagonal border and do not select the diagonal border type, the Borders.DiagonalBorderType property will be automatically set to DiagonalBorderType.UpAndDown. Use this diagonal border type if you want to specify both diagonal-up and diagonal-down borders for a cell. If it is required to set a cell diagonal border either from bottom left to top right or from top left to bottom right, set the Borders.DiagonalBorderType property to DiagonalBorderType.Up or DiagonalBorderType.Down, respectively. Note that if you specify different formats for diagonal-up and diagonal-down borders separately, only the last specified diagonal border will be applied.
Another way to set diagonal borders for a cell or range of cells is to call the Borders.SetDiagonalBorders method with the border color, line style and type passed as parameters.
To specify any other cell borders (e.g., top, bottom, left, right, inside and outside borders), use the corresponding properties and methods of the Borders object. Access this object via the cell or cell range Formatting.Borders property.
For examples on how to specify formatting for an individual cell and cell range, or modify a style, refer to the How to: Format a Cell or Range of Cells or How to: Create or Modify a Style document, respectively.
This example demonstrates how to specify different borders for individual cells and ranges of cells by modifying the Borders object.
