FailureValidationResult

Description

A FailureValidationResult is an interface that exposes the result of a failure validation of a datacell’s edited content.

Properties

Property	Type	Description
errorMessage	any	The validation error message.
isValid	boolean	false to indicate that the validation failed.

Example

The validateGreaterZero function receives a ValidationContext parameter and returns a FailureValidationResult when the dataCell’s edited value (retrieved from ValidationContext.newValue) is smaller than zero.

function validateGreaterZero(validationContext)

{

  if (validationContext.newValue < 0)

  {

    return {

      isValid: false, 

      errorMessage: “integer value must be greater than 0”

    };

  }



  return { isValid: true };

}

The validateGreaterZero function should be set as a ValidationRuleDefinition.validate function. This ValidationRuleDefinition should be set in the DataGridOptions.validationRuleDefinitions as a value. The key of this value should be used as the identifier on each of the columns needing this validationRule on the ColumnDefinition.validationRules property.
