Hi all

I'm using the BackStyle_Access method made popular by Craig Boyd and Burkhard Stiller. The method is added to a container in a column. By the way, is it only the container that makes the grid check the back_style? As you might know, the access method fires twice per row. I'm trying to avoid that, if possible. I will have to add the access method to a container that is very widely used. That means the access method will fire for every row and every column, even if I only want it for one column. It's also making tracing a bit of a pain since if I set step on, each of the calls to BackStyle_Access fires.

I thought I remembered that I could BindEvent to the BackStyle property so that when the grid interrogates the value on the container in the one column, I could trigger my routine. The help says we can bind to properties. It fires the delegate if I change a property, but not when I interrogate it. Is there flag I missed? The help does not mention that interrogating a property's value will not trigger the delegate.

Thanks for any advice.
