checkbox datagridview全选:

<pre name="code" class="csharp">/// <summary>
        /// 全选.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void chb_SelectAll_Click(object sender, EventArgs e)
        {
            foreach (DataGridViewRow row in dgv_Devices.Rows)
            {
                if (row.Cells[0] is DataGridViewCheckBoxCell)
                {
                    row.Cells[0].Value = chb_SelectAll.Checked;
                }
            }
        }

        private void dgv_Devices_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (dgv_Devices.SelectedRows.Count > 0)
            {
                DataGridViewRow dataGridViewRow = dgv_Devices.SelectedRows[0];
                if (dataGridViewRow.Cells[0] is DataGridViewCheckBoxCell)
                {
                    if (dataGridViewRow.Cells[0].Value == null)
                        dataGridViewRow.Cells[0].Value = true;
                    else
                    {
                        dataGridViewRow.Cells[0].Value = !((bool)(dataGridViewRow.Cells[0]).Value);
                    }
                }

                chb_SelectAll.Checked = dgv_Devices.Rows.Cast<DataGridViewRow>().Where(row => row.Cells[0] is DataGridViewCheckBoxCell).All(row => (bool)row.Cells[0].Value);
            }
        }
