Predefined Dialogs

The PdfViewer uses a number of predefined dialogs to display additional information to end users and prompt them for input. Each of the dialogs is opened by using the respective key combination or by explicitly invoking the respective command.

To be displayed, the dialogs have first to be registered either through the ExtensibilityManager helper class when using code-behind or through the respective attached property of the RadPdfViewerAttachedComponents class when defined in XAML.

The Find Dialog

The FindDialog dialog allows flexible searching in the loaded PDF document. For more information, refer to the article on the search functionality of the PdfViewer.

Register the FindDialog by using ExtensibilityManager

ExtensibilityManager.RegisterPasswordRequiredDialog(new FindDialog()); 

To add the dialog through XAML, use the RegisterFindDialog property of the RadPdfViewerAttachedComponents class.
