A WebDocumentViewerClientSideEventsBuilder that can be used to further configure the Document Viewer Client Side Events.

Parameter Editor

The CustomizeParameterEditors event enables you to customize parameter editors. When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientDocumentViewer object. The second one is an object with the following structure.

  • parameter
    An object that stores information about a parameter.

  • info
    An object that stores information required to serialize a parameter editor.

The code sample below demonstrates how to customize the editor used to display integer type parameters.
