Thanks Douglas.
Its looking like I need this or some other commercial software to do what I want.
Shame as I was hoping to do it in code as the app is a freebie.
[quote=469338:@Douglas Handy]Another alternative you can consider is piDog’s DataView class. It is pure Xojo code built upon a canvas, not subclassed from a ListBox. So it was able to implement TONS of stuff not easily supported by the standard Listbox class. I originally got it so I could handle column and row spans, and locked columns on the left. But since my original need, I have found it useful in so many other cases.
