}

　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;

        }

    }

}
