ParametersRequestExtension.RegisterExtension(ParametersRequestExtension, String) Method

Registers the custom parameters request extension, to implement custom parameter editors in a print preview.

Namespace: DevExpress.XtraReports.Extensions

Assembly: DevExpress.XtraReports.v19.1.Extensions.dll

NuGet Package: 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.
contextName	String	A String value, identifying the context.

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.
