Before we start, I'm a noob and have been looking everywhere but can't seem to find any code snippets that explain how to do this. I would like to be able to pass a color to a subreport as a parameter and set the Backcolor property of several elements with that parameter. My goal is to have all the code in the jrxml. I'd like to know how to reference or set these properties from a print when expression, for example. I believe there should be some way to reference these elements using the element key, but I can't figure it out. Any help would be greatly appreciated.
