How to set the color of a cell or range to transparent?

Question

I know how to set the color to red for example:

row.Interior.Color = Color.FromArgb(255, 0, 0);

But how to set the background to transparent?

Answer 1

It can be done by using System.Drawing.Color instead of Spreadsheetgear.Drawing.Color:

row.Interior.Color = System.Drawing.Color.Transparent;
