Element no longer read-only after undo

[lefrac01]

Given a read-only element, after the following code is run on it and the user presses undo, the element is not set back to read-only. I want to allow the user to delete an element with a button and be able to undo this action without losing the read-only protection.

ActiveDocument.BeginMutations(“example”)
rng.Select()
rng.ReadOnlyContainer = False
rng.NonRemovableContainer = False
rng.SelectElement()
rng.Select()
ActiveDocument.DeleteSelection()
ActiveDocument.EndMutations(True)

Hi,

You still can delete an element with readonly content directly.

The following 2 lines are not needed.

rng.ReadOnlyContainer = False
rng.NonRemovableContainer = False

Hello, thanks for the reply.

The requirement is for the content and also the element itself to be readonly.

Without both those lines the element is not deleted. If I leave only rng.NonRemovableContainer = False the element is deleted but is still editable after undo.

It looks like the undo feature is re-adding the XML content but not reapplying the readonly state.

Hi,

rng.ReadOnlyContainer = False
rng.NonRemovableContainer = False

The two lines about are not executed as commands. This is why they are not undoable.

At present, there is no workaround it. I will add the issue to the backlog of XMetaL 16.

Another method is to restrict formatting and editing. Making your document a read-only file means that the document can be read or copied but not modified.doramas yt
