起因：将 作为数据源加到DatagridView时，DatagridView正常显示。
代码如下：
代码如下：
this.DayPlan_DGView.DataSource = mDataSet_CyclePlan.Tables[0]; this.DayPlan_DGView.Columns[0].FillWeight = 85; //段号 this.DayPlan_DGView.Columns[1].FillWeight = 65; //开始时间：小时 this.DayPlan_DGView.Columns[2].FillWeight = 65; //开始时间：分钟 this.DayPlan_DGView.Columns[3].FillWeight = 330; this.DayPlan_DGView.Columns[4].FillWeight = 100;
此时运行正常.如下图
然后本人想在这个数据表中添加一列，带CheckBox的列：DataGridViewCheckBoxColumn列
代码如下：
DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn(); this.DayPlan_DGView.DataSource = mDataSet_CyclePlan.Tables[0]; // this.DayPlan_DGView.ColumnHeadersDefaultCellStyle.WrapMode = DataGridViewTriState.False; this.DayPlan_DGView.Columns[0].FillWeight = 85; //段号 this.DayPlan_DGView.Columns[1].FillWeight = 65; //开始时间：小时 this.DayPlan_DGView.Columns[2].FillWeight = 65; //开始时间：分钟 this.DayPlan_DGView.Columns[3].FillWeight = 330; this.DayPlan_DGView.Columns[4].FillWeight = 100; column.HeaderText = "选中"; column.Name = ""; column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells; column.FlatStyle = FlatStyle.Standard; column.ThreeState = true; column.CellTemplate = new DataGridViewCheckBoxCell(); column.CellTemplate.Style.BackColor = Color.Beige; this.DayPlan_DGView.Columns.Insert(4, column);
此时显示如下错误：
讨教本人应该说怎么做。
