| IsValid | Gets or sets a value which specifies whether the value is valid. |

The event data class exposes the following methods:
| Method | Description |

| SetError(Object) | Marks the processed input value as invalid and displays an error within the editor. |
Remarks
Handle the Validate event to manually validate the editor (e.g. to limit the range of valid values, implement a custom conditional validation mechanism, etc).
To specify when the editor should automatically validate its value, use the BaseEdit.ValidateOnEnterKeyPressed and BaseEdit.ValidateOnTextInput properties. To manually force the editor’s validation, call the BaseEdit.DoValidate method.
Note
The Validate event is not raised if the editor’s BaseEdit.CausesValidation property is set to false.
