c# datagridview DataGridViewCheckBoxCell 有趣的现象

Question

我在我的程序中发现了一个有趣的现象，我的程序中有两个带checkbox的datagridview，他们有一定的关联性，我想选中datagridview1中某一行的checkbox，选中后datagridview2中的相应行checkbox也被选中。
  private void dataGridView2_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex == 3)
            {
                if (dataGridView2.Rows[e.RowIndex].Cells[3].Value != null)
                {
                    if (Convert.ToBoolean(dataGridView2.Rows[e.RowIndex].Cells[3].Value.ToString()) == true)
                    {                        DataGridViewCheckBoxCell checkCell1 = (DataGridViewCheckBoxCell)dataGridView2.Rows[e.RowIndex].Cells["是否被选"];
                        checkCell1.Value = false;
                        DataGridViewCheckBoxCell checkCell2 = (DataGridViewCheckBoxCell)dataGridView5.Rows[e.RowIndex].Cells["是否被选"];
                        checkCell2.Value = false;
                      
                    }
                    else
                    {
                        DataGridViewCheckBoxCell checkCell3 = (DataGridViewCheckBoxCell)dataGridView2.Rows[e.RowIndex].Cells["是否被选"];
                        checkCell3.Value = true;
                        DataGridViewCheckBoxCell checkCell4 = (DataGridViewCheckBoxCell)dataGridView5.Rows[e.RowIndex].Cells["是否被选"];
                        checkCell4.Value = true;
                    }                }
                else
                {
  
                    this.dataGridView5["是否被选", e.RowIndex].Value = true;
                
                }
            }
        }但是我每次操作第一次无效，从第二次开始才能有效，不知为什么！ 即我第一次选中datagridview1中的某一行 datagridview2中相应行没有被选中，而从第二次开始才能被选中 哪位高手能告诉我这是为什么？

Answer 1

datagridview1和datagridview2都在前加上datagridview1.EndEdit()
datagridview2.EndEdit()
加在  if (dataGridView2.Rows[e.RowIndex].Cells[3].Value != null) 前面

Answer 2

帮你改好了我在本地测试过了，没有问题
        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            dataGridView1.BeginEdit();
            dataGridView2.BeginEdit();
            if (e.ColumnIndex == 0)
            {
                if (dataGridView1.Rows[e.RowIndex].Cells["Column1"].Value == "true")
                {                    DataGridViewCheckBoxCell checkCell1 = (DataGridViewCheckBoxCell)dataGridView1.Rows[e.RowIndex].Cells["Column1"];
                    checkCell1.Value = true;
                    DataGridViewCheckBoxCell checkCell2 = (DataGridViewCheckBoxCell)dataGridView2.Rows[e.RowIndex].Cells["Column2"];
                    checkCell2.Value = true;                }
                else
                {
                    DataGridViewCheckBoxCell checkCell3 = (DataGridViewCheckBoxCell)dataGridView1.Rows[e.RowIndex].Cells["Column1"];
                    checkCell3.Value = false;
                    DataGridViewCheckBoxCell checkCell4 = (DataGridViewCheckBoxCell)dataGridView2.Rows[e.RowIndex].Cells["Column2"];
                    checkCell4.Value = false;
                }
            }
        }

谢谢，我发现不是datagridview的问题，是tabcontrol的问题，我把两个datagridview分别放入tabcontrol中会出现这个问题，如果把tabcontrol去掉那种现象消失
