ValidationRuleDefinitionCollection / PartialValidationRuleDefinitionCollection

Description

A ValidationRuleDefinitionCollection is an interface that is used to store all the ValidationRuleDefinition of the DataGrid’s options. Each ValidationRuleDefinition is stored under a specific key. It extends ResourceCollection<ValidationRuleDefinition>.

Property

Property	Element	Type	Description
key		string	The identifier of the ValidationRuleDefinition.
	value	ValidationRuleDefinition	The ValidationRuleDefinition.

Example

The following validationRuleDefinitions defines three (3) ValidationRuleDefinition. Two (2) are custom by providing a validate function, and the third redefines the default range ValidationRuleDefinition by modifying its options.

const validationRuleDefinitions = {

  "greaterZero": { validate: validateGreaterZero },   //custom

  "lessTen": { validate: validateLessTen },   //custom

  "range": { options: { min: 0, max: 15, errorMessage: "Value must be between 0 and 15." } }   //redefine default

};

This validationRuleDefinitions can be used as the DataGridOptions.validationRuleDefinitions. The columns needing to use one of these ValidationRuleDefinition will need to add the validationRuleDefinition.key in their ColumnDefinition.validationRules property.

A partial type/interface is an object in which properties are optional.
