DataGridView 单元格中添加按钮

Question

有点BUG
以下修正        
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex.Equals(this.dataGridView1.Columns["Company"].Index))
            {                //this.dataGridView1.Controls.Clear(); 此处的清除控件应该放在CellLeave事件中处理
//
                Button btn = new Button();
                btn.Text = "...";
                btn.Font = new Font("Arial", 7);
                btn.Visible = true;
                btn.Width = this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Height;
                btn.Height = this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Height;
                
                this.dataGridView1.Controls.Add(btn);
                btn.Location = new System.Drawing.Point((this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true)
                    .Right - btn.Width), this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Y);
                btn.Click += new EventHandler(btn_Click);
            }        }
        void btn_Click(object sender, EventArgs e)
        {
            Form f = new Form();
            f.ShowDialog(this.dataGridView1);
        }        private void dataGridView1_CellLeave(object sender, DataGridViewCellEventArgs e)
        {
            this.dataGridView1.Controls.Clear();  //清除集合中控件
        }
