SetOutlineBorder - does not support bitwise operations

Something I noticed about doing borders which is kinda a pain the way you implemented it.

var r = ws.Cells.CreateRange(tr, sc, sr - tr, 1);
r.SetOutlineBorder(BorderType.TopBorder, CellBorderType.Double, Color.Red);
r.SetOutlineBorder(BorderType.BottomBorder, CellBorderType.Double, Color.Red);
r.SetOutlineBorder(BorderType.LeftBorder, CellBorderType.Double, Color.Red);
r.SetOutlineBorder(BorderType.RightBorder, CellBorderType.Double, Color.Red);

This works, but I thought we would be able to bit-wise OR these together so I could write....

r.SetOutlineBorder(BorderType.TopBorder | BorderType.BottomBorder | etc....., CellBorderType.Double, Color.Red); // does not support ORing these even though they are powers of 2.

Hi Marty,

Thanks for your posting and using Aspose.Cells.

Hopefully, it will work fine at your end. I have tried it with the following code and it works fine. I have attached the output xlsx file generated by it for your reference.

Let us know if you encounter any issue, we will look into it and help you further.


Workbook workbook = new Workbook();

Worksheet worksheet = workbook.Worksheets[0];

Range r = worksheet.Cells.CreateRange(“B2:C5”);

r.SetOutlineBorder(BorderType.TopBorder | BorderType.RightBorder, CellBorderType.Thick, Color.Red);
