Looks GetDataOfLine gets a key of a line, but the line is still a reference to the line in the data grid data, not the visible line. So if I have 15 lines with 8 visible, and I am scrolled to the bottom of the data grid and I want the last of the 8 visible lines, using getDataOfLine(8, "uniqueid") will give me uniqueid of the the 8th record, not the 15th, you see? The 8th visible line is the 15th *actual* line.
I came up with a way to do it though, but it assumes that the row height is fixed. You simple div the dgVScroll with the dgprops["row height"] and you have the number of previous (non-visible) rows. Now you can add that to the visible row number and you have the row to pass to dgDataOfLine. Kludgy but it works. Might be a nice to include in the datagrid library a dgDataOfVisibleLine property that takes into account variable row heights. I think I will add that to the QCC.
