I think the property is expecting for a single number value that represents the color.

Are you doing something like the following?

lcBackColor = "RGB(255,255,255)"
Grid.Column1.DynamicBackColor = &lcBackColor

I haven't tested it but think I remember from creating a class way back that you should probably let the RGB() function execute:

Grid.Column1.DynamicBackColor = RGB(255,255,255)

or 

lnBackColor = RGB(255,255,255)
Grid.Column1.DynamicBackColor = lnBackColor

I'm not sure this will work but just something off the top of my head.

Aloha,
