添加MouseEnter()与MouseLeave()事件。

/// <summary>
/// 用来记录先前的颜色值
/// </summary>
Color colorTmp = Color.White;
/// <summary>
/// 记录鼠标形状
/// </summary>
Cursor cursorTmp = Cursor.Current;
private void dataGridView1_CellMouseEnter( object sender, DataGridViewCellEventArgs e)
{
     if (e.RowIndex >= 0)
    {
        colorTmp = dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor;
        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Silver;
         if (e.ColumnIndex == 1) // 改变第二列鼠标形状
        {
            cursorTmp = this.Cursor;
             this.Cursor = Cursors.Hand;
        }
    }
}

private void dataGridView1_CellMouseLeave( object sender, DataGridViewCellEventArgs e)

     if (e.RowIndex >= 0)
    {
        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = colorTmp;

        {
             this.Cursor = cursorTmp;
        }
    }
}
