            dataGridView2.Controls.Add(box);
            Rectangle rec = dataGridView2.GetCellDisplayRectangle(i, j, true);

如果您使用的是CellContentClick事件或您获得的任何其他事件，DataGridViewCellEventArgs那么您拥有的单元格的列ColumnIndex和RowIndex行的属性已更改

看起来您尝试在不使用 a的情况下添加纯CheckBoxes ，这种方法的解决方案很简单，如下所示：DataGridViewDataGridViewCheckBoxColumn

for (int i = 0; i < dataGridView2.ColumnCount; i++)
    {
        for (int j = 0; j < dataGridView2.RowCount; j++)
        {
            box = new CheckBox();
            box.Text = "MyDate";
            //box.Size = new System.Drawing.Size(15, 15);
            dataGridView2.Controls.Add(box);
            Rectangle rec = dataGridView2.GetCellDisplayRectangle(i, j, true);
            box.Left = rec.Left;
            box.Top = rec.Top;
            //Added code
            box.Tag = new Point(i,j);
            box.Click += CheckBoxesClicked;
        }
    }
private void CheckBoxesClicked(object sender, EventArgs e){
   CheckBox chb = sender as CheckBox;
   if(chb.Tag != null) {
      Point coord = (Point)chb.Tag;
      MessageBox.Show(string.Format("Row index: {0}\nColumn index: {1}", coord.Y, coord.X);
   }
}     

您应该使用 aDataGridViewCheckBoxColumn相反，通过这种方法，您可以处理事件CellContentClick......
