ReportDesignerConfigurationBuilder.RegisterObjectDataSourceConstructorFilterService<T>() Method

Registers a class that implements the IObjectDataSourceConstructorFilterService interface to filter type constructors in the Report Wizard and Data Source Wizard.

Namespace: DevExpress.AspNetCore.Reporting

Assembly: DevExpress.AspNetCore.Reporting.v25.2.dll

NuGet Package: DevExpress.AspNetCore.Reporting

Declaration

C#

public ReportDesignerConfigurationBuilder RegisterObjectDataSourceConstructorFilterService<T>()
    where T : class, IObjectDataSourceConstructorFilterService

VB.NET

Public Function RegisterObjectDataSourceConstructorFilterService(Of T As {Class, IObjectDataSourceConstructorFilterService}) As ReportDesignerConfigurationBuilder

Type Parameters

Name	Description
T	The type of the class that implements the IObjectDataSourceConstructorFilterService interface.

Returns

Type	Description
ReportDesignerConfigurationBuilder	A ReportDesignerConfigurationBuilder class instance.

Remarks

A class that implements the IObjectDataSourceConstructorFilterService interface produces a filtered list of type constructors for the Report Wizard and Data Source Wizard. The RegisterObjectDataSourceConstructorFilterService<T>() method registers this class. Call this method at the application’s start.

A registered class should provide a complete list of constructors that are invoked to create an object data source. Classes passed in previous RegisterObjectDataSourceConstructorFilterService<T>() method calls are unregistered when you call this method again.

If the type’s constructor list is not provided or an IObjectDataSourceConstructorFilterService interface is not implemented or registered, the Report Wizard and Data Source Wizard display all constructors.

See the Business Object - Register Types topic for information on how to implement and register the IObjectDataSourceConstructorFilterService interface to filter type constructors.
