Remarks

The CustomizeMenuActions event enables you to customize the menu actions of the Document Viewer that is built into the Web Report Designer. When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientReportDesigner object. The second one is an object with the following structure.

• Actions
  A collection of Actions available in the Web Report Designer’ Document Viewer toolbar and menu.

• GetById
  This method allows you to obtain the required Action by its ID (ActionId value).

The following example demonstrates how to hide the existing Highlight Editing Fields toolbar command and add a new Run Slide Show command that navigates through document pages.
