What else I have to do in order to show ReadAccess enum members in this DatagridViewComboBox?
ReadAccess
ReadDataGridViewComboBoxColumn.Items.Clear(); ReadDa
You should not convert enum value to the int. Use this code if you have an error like "invalid value":
ReadDataGridViewComboBoxColumn.DataSource = new ReadAccess[] { ReadAccess.None, ReadAccess.Allowed } .Select(value => new { Display=value.ToString(), Value=value }) .ToList();
