WordsProcessing Protected Document Doesnt Unlock

[Erik]

I am generating a RadFlowDocument, and at the end protecting the entire document with a custom password like below..

                editor.Protect("TestPassword");

This works when I open the word document as expected, but when I go in MS Word to UNLOCK the document with my password, I am constantly told the password is incorrect.. Any advise on what I am doing wrong?

Hi, Erik,

Your question has already been answered in the support thread, Ticket ID: 1659187, you have opened on the same topic. However, I am posting the answer here as well in order the community to benefit from it.

Following the provided information, I have prepared a sample project to test the behavior on my end:

            RadFlowDocument document = new RadFlowDocument();
            RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
            editor.InsertText("Hello world!");

            editor.Protect("telerik", Telerik.Windows.Documents.Flow.Model.Protection.ProtectionMode.ReadOnly);

            Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
            string outputFilePath = "ProtectedDocument.docx";
            File.Delete(outputFilePath);
            using (Stream output = File.OpenWrite(outputFilePath))
            { 
                provider.Export(document, output);
            }
            Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });

It seems to work as expected and when I enter the password to a protected document with ProtectionMode.ReadOnly, it allows editing:

More information about the supported protection modes is available in the following section of the online documentation: Operating with Permission Ranges.

If you are observing a different behavior than the illustrated one from the above gif, please let me know what are the exact steps that are needed to observe the undesired behavior.

Dess, 

Thank you for this response! I have solved my issue.. I didn't know that there was a password length maximum on an MS Word Document..

To replicate exactly what I was doing, use a password that is 16 or more characters.. When you do so, even if the first 15 you type are correct, it says the password is incorrect.. If you insert a password that is 15 or less characters, the unlock works as expected..

Thank you again for your help!
