Parameters

Type Name Description
ParametersRequestExtension extension

A ParametersRequestExtension object.

String contextName

A String value, identifying the context.

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.
