在请教个问题啊，查了好多资料一直没解决，我想选中时右键的快捷菜单可用，否则不可用。代码如下：但选中了还是不会变化，求解！
  private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
      {

         if (dataGridView1.IsCurrentCellDirty)
            {
               dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
            }
      }

      private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
      {

      if (dataGridView1.Rows.Count > 0)
         {
               for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {

                  string _selectValue = dataGridView1.Rows.Cells[1].EditedFormattedValue.ToString();
                     if (_selectValue= "True")
                     {
                        //MessageBox.Show("选中");
                        详细信息ToolStripMenuItem.Enabled = true;
                     }
                     else
                     {
                        //MessageBox.Show("未选中");
                        详细信息ToolStripMenuItem.Enabled = false;
                     }

            }
         }
      }

      private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
      {
         dataGridView1.CurrentCellDirtyStateChanged += new EventHandler(dataGridView1_CurrentCellDirtyStateChanged);
         dataGridView1.CellValueChanged += new DataGridViewCellEventHandler(dataGridView1_CellValueChanged);
      }

  /// <summary>
      /// 列表单机鼠标发生
      /// </summary>
      /// <param name="sender"></param>
      /// <param name="e"></param>
      private void dgvData_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
      {
         if (e.Button == System.Windows.Forms.MouseButtons.Right && e.ColumnIndex > -1 && e.RowIndex > -1)  //点击的是鼠标右键，并且不是表头
         {
            //右键选中单元格
            this.dgvData.Rows[e.RowIndex].Selected = true;
            this.skinContextMenuStrip.Show(MousePosition.X, MousePosition.Y); //MousePosition.X, MousePosition.Y 是为了让菜单在所选行的位置显示
         }
      }
这样显示右键  看清楚事件
