NonPersistentObjectSpace.GetObjectsCount(Type, CriteriaOperator) Method

Returns the number of objects specified.

Namespace: DevExpress.ExpressApp
Assembly: DevExpress.ExpressApp.v18.1.dll
public override int GetObjectsCount(Type objectType, CriteriaOperator criteria)
Type Name Description
Type objectType

A Type object that identifies the type of objects against which the calculation will be performed.

CriteriaOperator criteria

The CriteriaOperator that specifies the criteria for object selection.

Type Description

An integer value that is the count of non-persistent objects that satisfy the specified criteria.

You can handle the NonPersistentObjectSpace.ObjectsCountGetting event to supply custom logic for calculating the GetObjectsCount result. If the ObjectsCountGetting event is not handled, or if the ObjectsCountGettingEventArgs.Count is null, the GetObjectsCount method calls the IObjectSpace.CreateCollection method to calculate the count.
