Open a Document Read-Only
Sometimes, you may have a document that needs a review, but you do not want reviewers to randomly modify your content. Aspose.Words allows you to make the permission of your document read-only so that the content can be copied or read, but not modified. This will prevent content from being removed or added to your document.
This article explains how to make a document read-only.
Make a Document Read-Only
Aspose.Words has the public class WriteProtection that specifies write protection settings for a document. You do not create instances of this class directly.
Write protection shows whether the author has recommended opening a document as read-only and/or requiring a password to modify the document.
In Microsoft Word, you can create a Read-Only document in a similar way using both:
- “Always Open Read-Only” (File → Info → Protect Document)
- “Password to modify” (Save As → Tools → General Options → Password)
Users can also restrict document editing by selecting ProtectionType as ReadOnly, but this is another feature that provides more advanced protection capabilities. There is such a function in Microsoft Word, respectively, it is implemented in Aspose.Words.
ProtectionType will be described in detail in one of the following articles – “Restrict Document Editing”.
The ReadOnlyRecommended property is password-secured, so if you do not set a password before applying the ReadOnlyRecommended property, then other users can simply open the document as if it were unprotected. You access the document protection settings and set a write protection password via the SetPassword method.
If you need to check if a document has a write protection password that restricts it from editing, you can use the IsWriteProtected property.
The following code example shows how to make a document read-only:
Remove Read-Only Restriction
If you do not want a user to open your document as read-only, you can simply set the ReadOnlyRecommened property to false or select ProtectionType as NoProtection.
The following code example shows how to remove read-only access for a document:
