Hi Martin

I can make different images appear if I use the DynamicBackcolor property to call a method that sets the picture but this is a workaround and clearly not obvious to anyone when they first try to show images.

As far as Calculated Fields go you can do as you suggested but this is of limited use. I often use a Method to return the data I wanted displayed because I may have to use data combined from several tables requiring the use of the Seek() function etc. In the past if the string you assigned to the ControlSource approach 200 or so characters strange things began to happen in the grid. It would be much better if you could simple set the ControlSource to call a method directly then you are free to do what ever you can imagine.

Regards,
Simon White

I have begun looking at it again in VFP9 but still discovered some missing pieces. For example, you have to revert to tricks to get a different image on each row of the grid.
