Marcus's answer is correct, but you may also need to set the current cell property of the DataGridView ...
dgv.CurrentCell = dgv.Rows[0].Cells[0];
I believe this will scroll the grid. Also, to be completely safe, you can add this before another line of code ...
dgv.CurrentCell = null;
This will ensure that if the row you want is already the active row, but just scrolls out of view, it will scroll back into view.

You need to clear the old position and set the new one.
The data of the GridView1.SelectedRows collection has the currently selected rows. Depending on the MultiSelect property of the grid, you may need to loop through all the rows in the SelectedRows and mark them as unselected. If you are the only selection mode, simply set the new row as selected to clear the old selection.
To select a specific row (in this case one of the indices 0), you simply add the row dataGridView1.Rows [0] .Selected = true;

Private Sub GridSaleItem_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridSaleItem.SelectionChanged
Dim rowcount As Integer
rowcount = GridSaleItem.Rows.Count
For i As Integer = 1 To rowcount
If i = 1 Then
'
Else
If i = rowcount Then
Me.GridSaleItem.CurrentCell = Me.GridSaleItem.Rows(i - 1).Cells(0)
Me.GridSaleItem.Rows(i - 1).Selected = True
End If
End If
Next
End Sub
You seem to need not only setting the selected row, but also the displayed row. You can access the latter using a property FirstDisplayedScrollingRowIndex
in your DataGridView. One of the useful settings:
int lastShown = FirstDisplayedScrollingRowIndex + DisplayedRowCount(false) - 2;
if (lastShown < yourIndex)
FirstDisplayedScrollingRowIndex += yourIndex - lastShown;
else if (FirstDisplayedScrollingRowIndex > yourIndex)
FirstDisplayedScrollingRowIndex = yourIndex;
make sure your newly selected row doesn't disappear from the screen when scrolling up / down programmatically.
