| Key | `public string Key { get; set; }` | The model-state key with `.` replaced by `_` for DOM-element-id safety. |
| Values | `public string[] Values { get; set; }` | All error messages associated with the key. |
| GridRowId | `public string GridRowId { get; set; }` | The correlated grid row identifier, or `""` when the key does not participate in grid-row correlation; see [BR-36](../../business-rules.md#br-36-error-keys-are-dom-safe). |
