Property DiagonalBorderColor As Color
| Type | Description |
|---|---|
| Color |
A Color value specifying the border line color.
|
To specify characteristics of cell diagonal borders, use the DiagonalBorderColor , Borders.DiagonalBorderLineStyle and Borders.DiagonalBorderType properties.
If you set a color and line style for 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, change the Borders.DiagonalBorderType property value. Note that if you specify different formats for diagonal-up (DiagonalBorderType.Up) and diagonal-down (DiagonalBorderType.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 a 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’s or cell range’s 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.
