Enrico,

Then create a cursor that only contains a single one character column and has as many rows as your source. A little visual fiddling with the grid and I think you can get it to look right. The grid scroll thumb works well up to a few million rows before it starts misbehaving.

>Yes, of course. But in my case I have to display anything. I only need to reflect "exactly" the position of one of my tables, and I want give the ability to change interactively this position. I thought that scroolbar was the correct control for my need, but max number of position is too limitative. Browse object need of course that I have a opened table and in some circumstance this is not true in my application.
