Hi!
I have successfully created a docx from a dotx with C#/OpenXML. I added an XML with some properties and the docx gets populated just fine with the custom values. I upload the document to SharePoint Online and can preview the document just fine. When i try to edit the document all the custom properties that have been populated are grayed out and can't be edited. I guess this is a limitation in OWA/WAC but i would like to get this confirmed and i have not been able to find any information regarding this. I've also tried to use "built in" properties like Title, Author and so on but the result is the same.
Thank you!
EDIT:
If there is any workaround for the "issue" i would appreciate any guidance. Is there any way to "print" the contents of the document to a new blank docx so that all the mappings/xml-stuff are removed? If thats possible that would absolutely be a good workaround.
