RuleSet.ValidateAllTargets(IObjectSpace, IEnumerable, ContextIdentifiers) Method

Silently (without raising the RuleSet.ValidationCompleted event and throwing the ValidationException) validates multiple targets and returns the result.

Namespace: DevExpress.Persistent.Validation

Assembly: DevExpress.Persistent.Base.v18.2.dll


public RuleSetValidationResult ValidateAllTargets(
    IObjectSpace targetObjectSpace,
    IEnumerable targets,
    ContextIdentifiers contextIDs
Public Function ValidateAllTargets(
    targetObjectSpace As IObjectSpace,
    targets As IEnumerable,
    contextIDs As ContextIdentifiers
) As RuleSetValidationResult


Type Name Description
IObjectSpace targetObjectSpace

An IObjectSpace used by a validation target.

IEnumerable targets

The list of objects to check.

ContextIdentifiers contextIDs

The ContextIdentifiers object which is a set of validation contexts, rules for which will be collected. Default contexts are stored in the DefaultContexts enumeration.


Type Description

The result of the RuleSet validation.


Below is the example of using the ValidateAllTargets method and handling its result.

RuleSetValidationResult validationResult = Validator.RuleSet.ValidateAllTargets(
    ObjectSpace, ObjectSpace.GetObjectsToSave(false), ContextIdentifier.Save);
ValidationResults obj = new ValidationResults(validationResult, base.Application.Model);
bool flag = validationResult.State != ValidationState.Invalid;

This method raises the RuleSet.RuleValidated event for each target.
