ValidationCategories Enumeration
This enumeration is a parameter for the constructor of the custom attribute, ValidationMethodAttribute. It specifies the type of validation in which the rule will be invoked.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Members
| Member name | Description | |
|---|---|---|
| Menu | The method is invoked when the user selects ValidateAll on the shortcut menu. | |
| Open | The validation method is invoked when the model is opened. | |
| Save | Indicates that the validation method is invoked before a user of the domain-specific language saves the model. | |
| Custom | The method is for custom validation. To run this method, you can call ValidationController.ValidateCustom(). | |
| Load | Use this category for rules that check for conditions that will keep the model from loading. The method is invoked before a domain-specific language model is saved, to give the user a chance to correct any problems.
If a Load rule fails when the model is loaded, the model file will be opened with the XML editor rather than the DSL Designer. |
Remarks
This is a bitwise enumeration. The flags are not mutually exclusive.
Examples
The following example shows the ValidationCategory of a method in the Person class that is invoked when the user of a domain-specific language opens a model, saves a model, or clicks the validation command on the shortcut menu.
