If you get the same error when you hardcode the value, you know that bad input is not causing the problem. Taking a look at the error message, it seemss to tell you two things: you are using BackgroundImage as a property, and BackgroundImage is actually a method. This may mean that either the declaration of BackgroundImage is incorrect, or your usage of it is incorrect. Did you produce the custom class yourself? If so, take a look at your declaration of BackgroundImage. If not, look at the documentation for the usage of BackgroundImage. Post the code, if you're in any doubt.
