Disable caching, downloading printing etc?

[Tommy]

We need to let users view sensitive documents within our application so would like to make sure they cannot be downloaded to the local machine, printed etc. Does the Telerik PDF Viewer cater for this?

Hi Tommy,

The general idea of the component is simply to provide previewing functionality of the PDF. The PDF file has to be sent to the client browser to be previewed. One way to prevent downloading and printing from the PDFViewer would be to set the .ToolBar() configuration to false to not display a Toolbar, or configure it to display only the required controls. Other way would be to hide controls using CSS. Keep in mind that unfortunately there is no way to restrict the access to the file. If there is no file on the client, the widget will have nothing to show.
