Description Eugene Belyakov 2016-02-20 13:08:18 UTC
It seems that property FirstDisplayedScrollingRowIndex of DataGridView does not implemeted.
It does not work in both directions (setter/getter).
I can set new value to FirstDisplayedScrollingRowIndex, but nothing happens with grid.
Aslo FirstDisplayedScrollingRowIndex remains unchanged When I do scrolling manually.

I found a workaround:

//Next string does not work:
//gridView.FirstDisplayedScrollingRowIndex = index;

//Looks ugly, but works
gridView.CurrentCell = gridView.Rows [gridView.RowCount-1].Cells [0];
gridView.CurrentCell = gridView.Rows [index].Cells [0];
gridView.CurrentCell = gridView.Rows [index].Cells [0];

I tried to use "gridView.CurrentCell =..." only once, but have unexpected scrolling position after gridView.Rows.Clear() and when adding new rows.
