ReadOnly Property LeftBorder As Border

Property Value

Type	Description
Border	A Border object that specifies characteristics of a cell border.

Remarks

Use the Border.LineStyle and Border.Color properties of the object returned by LeftBorder to set the characteristics of the cell’s left border.

To specify each border of a cell or cell range individually (e.g., top, bottom, left, right, diagonal, 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.

• To specify borders of an individual cell, access the Borders object using the cell’s Formatting.Borders property directly.
• To specify borders of the cell range, modify the Borders object within the CellRange.BeginUpdateFormatting - CellRange.EndUpdateFormatting method pair.
• To share the same border settings between multiple cells in one step, apply the style with the specified borders to the required cells. To specify borders for a cell style, access the Style object from the IWorkbook.Styles collection and use the Formatting.Borders property within the Formatting.BeginUpdate-Formatting.EndUpdate paired methods to access and modify the Borders object.

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.

Example

This example demonstrates how to specify different borders for individual cells and ranges of cells by modifying the Borders object.
