private void datagv_det_CellEnter(object sender, DataGridViewCellEventArgs e)
        {
             
            if (e.ColumnIndex.Equals(this.datagv_det.Columns["item"].Index))
            //判断单元格是否是"Company"列？ 
            {
                System.Windows.Forms.Button btn = new System.Windows.Forms.Button();//创建Buttonbtn 
                btn.Text = "..";//设置button文字 
                btn.Font = new System.Drawing.Font("Arial", 7);//设置文字格式 
                btn.Visible = true;//设置控件允许显示

                btn.Width = this.datagv_det.GetCellDisplayRectangle(e.ColumnIndex,
                                e.RowIndex, true).Width/5;//获取单元格高并设置为btn的宽 
                btn.Height = this.datagv_det.GetCellDisplayRectangle(e.ColumnIndex,
                                e.RowIndex, true).Height;//获取单元格高并设置为btn的高

                btn.Click += new EventHandler(btn_Click);//为btn添加单击事件

                this.datagv_det.Controls.Add(btn);//dataGridView1中添加控件btn

                btn.Location = new System.Drawing.Point(((this.datagv_det.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Right) -
                        (btn.Width)), this.datagv_det.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Y);//设置btn显示位置 

            }


        }

        private void btn_Click(object sender, EventArgs e)
        {

            frm_purchase_query f = new frm_purchase_query();
            f.ShowDialog(); 

        }

        private void datagv_det_CellLeave(object sender, DataGridViewCellEventArgs e)
        {
            this.datagv_det.Controls.Clear();//移除所有控件

        }
