  Ravi -

  You need to set the BackColor for the DefaultStyle of the sheet(s) and set it to Color.FromArgb(x,x,x,x) where the first x is the opacity you want to use.

  Not sure what you mean by 'transparent to that particular spread only'.  What else is it supposed to be transparent to?

  I think I may be having the same problem where I put the Spread control over a PictureBox and I cannot make the Spread Control transparent so I can see part of the image behind it. I suspect that I’m being blind to something as I have been using the Spread COM control for many years and am new to VB.NET. I tried “Spread1.BackColor = Color.Trasnparent” and also tried “Spread1.BackColor = Color.FromArgb(0, 255, 255, 255)”.

  Are there other steps that I need?
