Example

Setting document viewer permissions in code:

C#
//allow all set of permissions (default value)
documentViewer.AllowedPermissions = DocumentViewerPermissions.All;

//allow only Download and Print permissions
documentViewer.AllowedPermissions = DocumentViewerPermissions.Download | DocumentViewerPermissions.Print;

//allow all except Download and Print permissions
documentViewer.AllowedPermissions = DocumentViewerPermissions.All;
documentViewer.DeniedPermissions = DocumentViewerPermissions.Download | DocumentViewerPermissions.Print;

//allow all set of permissions and also add OpenLocalPdf which is not included in all
//OpenLocalPdf shows "Open" menu item for opening local PDF files (client-side, useful for testing PDF files)
documentViewer.AllowedPermissions = DocumentViewerPermissions.All | DocumentViewerPermissions.OpenLocalPdf;

Setting document viewer permissions in ASPX markup:

ASPX
<%-- allow all set of permissions (default value) --%>
<GleamTech:DocumentViewerControl runat="server" 
    Width="800" 
    Height="600" 
    Document="~/Documents/Document.docx"
    AllowedPermissions="All" />

<%-- allow only Download and Print permissions --%>
<GleamTech:DocumentViewerControl runat="server" 
    Width="800" 
    Height="600" 
    Document="~/Documents/Document.docx"
    AllowedPermissions="Download, Print" />

<%-- allow all except Download and Print permissions --%>
<GleamTech:DocumentViewerControl runat="server" 
    Width="800" 
    Height="600" 
    Document="~/Documents/Document.docx"
    AllowedPermissions="All"
    DeniedPermissions="Download, Print" />

OpenLocalPdf Ability to open local PDF files, i.e. user is shown "Open" menu item which is when clicked shows browser's open dialog to choose a PDF file to load. This permission is not included in All permission so it should be added additionally.

Note that only PDF files can be opened this way and not other formats because file is not processed on the server side (no conversions), and it's loaded by client-side DocumentViewer directly (same for attachments, non-PDF attachments will trigger download only and not load). However, it can be useful to test quickly, how a specific PDF file is rendered in the DocumentViewer.

EditAnnotations Ability to edit annotations of the document. Tools like Add Signature, Highlight, Draw, Add Image will be available. If no ViewAnnotations permission, then you can add new annotations but not view and edit existing ones.
All All the permissions combined.
