I heve the flowing things in my form:
1. text box.
2. grid.
The grid name is 'grdinvres' and the grid label name is 'txtinv'.
When the user fill the text box, I have a method that populating the grid with genxtab cursor.
For example: the text box is invoice # and the grid showing details.
I want to change the grid fonts acc the product values.
I hope it's enough clear.
