Show cell value as tool tip for a Windows Form Grid

Very nice..I was looking for such a code. I added one more line to avoid error on hovering mouse elsewhere in the DataGridView.

private void gridView1_CellToolTipTextNeeded(object sender,
    DataGridViewCellToolTipTextNeededEventArgs e)
{
if (e.ColumnIndex == -1 || e.RowIndex == -1) return;
    if (e.ColumnIndex == 0)
        e.ToolTipText = "PrintPreview";
    ...
}
