Question

我尝试将所选行从一个数据网格视图传输到另一个数据网格视图。我使用combobox textchange事件将所选数据加载到datagrid。因此，转移代码需要为dataGridView1.AllowUserToAddRows = false;执行dataGridView。但由于使用了combobox textchange事件，我无法禁用添加新行。怎么解决这个？我使用以下代码来传输值：

private void btnaddtoanother_Click(object sender, EventArgs e)
    {
        for (int i = 0; i <= dataGridView2.Rows.Count - 1; i++)
        {
            bool rowAlreadyExist = false;
            bool checkedCell = (bool)dataGridView2.Rows[i].Cells[0].Value;
            if (checkedCell == true)
            {
                DataGridViewRow row = dataGridView2.Rows[i];
                if (dataGridView1.Rows.Count != 0)
                {
                    for (int j = 0; j <= dataGridView1.Rows.Count - 1; j++)
                    {
                        if (row.Cells[0].Value.ToString() == dataGridView1.Rows[j].Cells[0].Value.ToString())
                        {
                            rowAlreadyExist = true;
                            break;
                        }
                    }
                    if (rowAlreadyExist == false)
                    {
                        dataGridView2.Rows.Add(row.Cells[0].Value.ToString());
                        dataGridView2.Rows.Add(row.Cells[1].Value.ToString());
                        dataGridView2.Rows.Add(row.Cells[3].Value.ToString());
                    }
                }
                else
                {
                    dataGridView2.Rows.Add(row.Cells[0].Value.ToString());
                    dataGridView2.Rows.Add(row.Cells[1].Value.ToString());
                    dataGridView2.Rows.Add(row.Cells[3].Value.ToString());
                }
            }
        }
    }

在尝试将其添加到新网格之前，先从网格中删除该行。

foreach (GridViewRow row in fromGridView.SelectedRows.OfType<DataGridViewRow>().ToArray())
{
    fromGridView.Rows.Remove(row);
    toGridView.Rows.Add(row);
}

如何将选定的行从一个datagridview传输到另一个？
