VS2005的datagridview控件，DataGridViewCheckBoxColumn问题？

Question

我在使用VS2005，C#开发C/S结构程序中用到了datagridview控件。并使用了DataGridViewCheckBoxColumn和DataGridViewLinkColumn，可得到显示结果的最后一行多了带CHECKBOX的空行。有什么方法不让最后带CHECKBOX的空行显示。我试了循环隐藏最后一行和移除最后一行都没有成功。忘达人指点!简单代码如下：                this.dataGridView1.DataSource = dt;  //dt为从ORACLE9I中读取的DataTable
                this.dataGridView1.AutoGenerateColumns = false;
                
                 dataGridView1.Columns.Insert(0, new DataGridViewCheckBoxColumn());
                 for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
                 {
                     
                     dataGridView1.Rows[i].Cells[0].Value = false;
                     
                 }
                
                dataGridView1.Columns[0].Resizable = DataGridViewTriState.False;
                dataGridView1.Columns[0].Frozen = true;
                dataGridView1.Columns[0].Width = 25;
                                DataGridViewLinkColumn dc = new DataGridViewLinkColumn();
                dc.Text = "详细";
                dc.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.AllCellsExceptHeader;
                dc.LinkBehavior = System.Windows.Forms.LinkBehavior.NeverUnderline;
                dc.UseColumnTextForLinkValue = true;
                dc.Frozen = true;
                dc.Width = 21;
                this.dataGridView1.Columns.Insert(1,dc);
             
                MessageBox.Show(dataGridView1.Rows.Count.ToString());                dataGridView1.Rows.RemoveAt(dataGridView1.Rows.Count-2);
                foreach (DataGridViewColumn c in dataGridView1.Columns)
                    if (c.Index != 0 && c.Index != 1) c.ReadOnly = true;

DataView dv = dt.DefaultView;//dt为从ORACLE9I中读取的DataTable
dv.AllowNew = false;
this.dataGridView1.DataSource = dv;
