Hi Aykut,

I fear you may be out of luck since as far as I know the Format16bppGrayScale mode is broken, and won't be fixed in Framework 2.0 either. Most likely you will need to convert the data to 8 bit indexed bitmap and fill the palette with grayscale values.

This thread discusses displaying 16bit grayscale using a Windows Bitmap object (GDI, but the GDI+ is closely related). Although the conversion is from 16 bit to 8 bit, the principles are the same as for 12 -> 8, depending.
