I haven't really started to poke around on how to accomplish this but am thinking I will need to create a subclass of MicroFour.StrataFrame.Business.BusinessLayer add a property to store the back color.

Then in some Form method\event? add the code to loop through the required fileds collection and the forms controls and set the approriate back colors on the controls that are bound to required fields. So I guess my question is what would be the appropriate event to add the code to do this. Or is there a better way to accompish this?

Any pushes/shoves in the right direction would be welcome.

Thanks

Paul
