Detect data scroll in a datagrid

[Bob Sneidar]

Hi all. 

I know I can detect dgScrollBarDragV, but that gets sent whether or not the actual data scrolls. It is possible to move the elevator box a slight bit and not have it effect the data in the datagrid. I only want to know what the visible data has changed. Any ideas? I already looked through the DG library and anything I might have used there seems to be private commands and functions.
