Right. I create MyGrid class. Add prop MyColor to grid. Add code to grid AARC to set DynamicColor stuff.

I also create MyTextBox class. Add this.backcolor = this.parent.parent.MyColor to gotfocus event.

In MyGrid init add code to addobject MyTextBox to each column.

Now I drop MyGrid on a form run it and it works fine.

A side effect of this is that you can't add any code to the grids text box without doing it at the MyTextBox class level.

If I drop Mygrid on a form and want to add some code to the text box click I can't, it gets replaced at runtime.
