Namespace: DevExpress.XtraReports.Extensions

Assembly: DevExpress.XtraReports.v21.2.Extensions.dll

NuGet Packages: DevExpress.Win.Design, DevExpress.Win.Reporting

Declaration

C#

public static void RegisterExtension(
    ParametersRequestExtension extension,
    string contextName
)

VB.NET

Public Shared Sub RegisterExtension(
    extension As ParametersRequestExtension,
    contextName As String
)

Parameters

Name	Type	Description
extension	ParametersRequestExtension	A ParametersRequestExtension object.

Remarks

To provide editors to parameters of custom types in a print preview, create a custom parameters request extension inherited from the ParametersRequestExtension class.

Then, register the extension (using the RegisterExtension method) and associate the report with the custom extension (using the ParametersRequestExtension.AssociateReportWithExtension method).

For a code sample, see How to create parameter editors that are dependent on each other’s values.
