DocumentViewerControl Class

DeniedPermissions take precedence over AllowedPermissions. For instance, when AllowedPermissions is set to All and DeniedPermissions is set to Download and Print, all permissions except Download and Print will be allowed.

When combining permissions, they should be separated by comma in string and by bitwise 'or' operator in code (| in C# and OR in VB).

It is usually set as the two-letter language names like en, de, fr etc. as the bundled languages are usually for general language names. However it can be also set to specific cultures like en-US, de-DE, fr-FR etc. For example, if the property is set to a specific culture like de-CH (German in Switzerland), the component will first look for the language file translation-de-CH.json and if the file is not found, it will load the general (fallback) language file of that culture which is translation-de.json. If not set, the language file which matches the current UICulture of the host application will be loaded. If there is no language file which matches the current UICulture or its fallback, then the default language file translation-en.json is loaded.

This property can be set to:

• A plain string which contains a physical/virtual path
  (e.g. "c:\SomeFolder\SomeFile.ext", "/SomeFolder/SomeFile.ext", "~/SomeFolder/SomeFile.ext").
  
  This is parsed as a FileSystemFileProvider instance with a PhysicalLocation instance. Note that virtual paths can only be resolved in a web application.
  and on Linux paths starting with "/" are physical paths and not virtual paths.
  
  
• A plain string which contains a URL or a Data URL.
  (e.g. "http://example.com/SomeFolder/SomeFile.ext", "data:image/gif;base64,...").
  
  Strings starting with http:// or https:// are parsed as a UrlFileProvider instance.
  Strings starting with data: are parsed as a DataUrlFileProvider instance.
  
  
• A FileProvider instance created with one of the builtin file providers
  (e.g. FileSystemFileProvider, UrlFileProvider, DataUrlFileProvider, StreamFileProvider, MemoryFileProvider, DatabaseFileProvider, AssemblyResourceFileProvider, TemporaryFileProvider).
  
  You can also override FileProvider base class to implement your custom file provider.
  
  
• A provider string which defines a specific file provider
  (e.g. "Type=FileSystem; File=SomeFile.ext; Location='Type=Physical; Path=c:\SomeFolder'").
  
  

The document viewer only needs a readable file provider as it only calls GetInfo and OpenRead.

You can specify document format, password, watermarks, attachments etc.

Format language is used for the number and date/time formats. It is usually set as the specific cultures like en-US, de-DE, fr-FR etc. If not set, the current Culture of the host application will be used.

Note that using full document viewer on mobile devices would cause performance issues (slow rendering), so you should prefer mobile document viewer which is optimized for mobile devices.

For this property to be effective PageFitMode property should be set to Zoom.

The options will be reflected as default values on the print dialog of the document viewer.

If you specify a search term, an automatic search will be done when the document is displayed, i.e. the specified term will be searched and results with clickable positions will be listed on the left pane and the term will be highlighted in the pages. For example, if you launch the document viewer from a search results page, you can pass the same search term to the document viewer.
