Your class is so good that I just want to do more and more - sorry!

If I use a check box as per your sample form with the following code

THIS.VALUE =THIS.VALUE
THIS.PARENT.Gridhighlighter1.SetDynamicColor()
THIS.PARENT.Grid1.REFRESH()

I can get the grid to display my ccustomcondition whenever I check the box- works beautifully

How can I get the grid to show the result of this condition every time it refreshes?

Thanks

Colin
