Avoid dipalying an icon at column 0 of a grid
#1
The routine which it follows displays perfectly information on a grid, with icons at columns 0 and 2. I am wondering about the best way to stop displaying the icon at all rows in column 0, under certain circumstances.




Code:
Select All      Help
Let me add that my best approach was to replace last statement in sub "IconCol0" as "col0[]=-1".
Any advice is much appreciated.
