使用：
private void dgvView_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (e.RowIndex < 0 || e.ColumnIndex > colSelect.Index) { return; }
DataRow dr = (dgvView.Rows[e.RowIndex].DataBoundItem as DataRowView)?.Row;
if (dr != null)
{
string status= DataFun.ConvertToStringByDB(dr["status"]);
if (status!= 'Doing')
{
DataGridViewDisableCheckBoxCell checkCell = (DataGridViewDisableCheckBoxCell)dgvView.Rows[e.RowIndex].Cells[colSelect.Index];
if (checkCell == null) { return; }
checkCell.Enabled = false;
checkCell.ReadOnly = true;
}
}
}
