One way to do this is manipulate the XML document that is the report definition before loading it into your Report Viewer control. You could use string find and replace code, or browse through using an XmlDocument object, adjusting all the colour values before dropping it in the viewer. You could then activate this code from elsewhere in your application.

Thank You for reply, but this way I will not be able to convert color pictures to black & white.
Any idea?

Technically, you could in the same fashion, you can alter the value of the image boxes to point to a black and white version of the image (say you had a duplicate set of images suffixed _bw, you could just add that to the filename)

If images are dynamic, you could always use GDI+ code to convert images at runtime to black and white, then save them and point the report definition to them
