NuGet Package: DevExpress.Persistent.Base

Declaration

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

VB.NET

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

Parameters

Name	Type	Description
targetObjectSpace	IObjectSpace	An IObjectSpace used by a validation target.
targets	IEnumerable	The list of objects to check.
contextIDs	ContextIdentifiers	The ContextIdentifiers object which is a set of validation contexts, rules for which will be collected. Default contexts are stored in the DefaultContexts enumeration.

Remarks

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

C#

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;

VB.NET

Dim validationResult As RuleSetValidationResult = Validator.RuleSet.ValidateAllTargets( _
ObjectSpace, ObjectSpace.GetObjectsToSave(False), ContextIdentifier.Save)
Dim obj As New ValidationResults(validationResult, MyBase.Application.Model)
Dim flag As Boolean = validationResult.State <> ValidationState.Invalid

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