How to change segment pair attributes - IsLocked - and refresh the editor screen ??

Hi there,

I'm currently struggling with something which should be quite simple..

By clicking on a custom ribbon button I'd like to

1. loop over the segment pairs displayed in the editor
2. based on a predicate set their property to IsLocked = true
3. change the display filter to "view only locked"
4. refresh the editor grid.

My neurons are probably affected by the flu, because I couldn't make it work..

My main difficulties are:

1. I can't change and persist the IsLocked property as it switches automatically back to false
2. I can't call a refresh on the EditorController because of it's protection level applied to the AbstractViewController
3. I never found in the documentation how to change the display filter.

Any help would be much appreciated,

have a great day ...


Code :

        public class ApplyAction : AbstractViewControllerAction<EditorController>
            protected override void Execute()
                foreach (var s in Controller.ActiveDocument.SegmentPairs)
                    if (/*specific condition*/)
                        s.Properties.IsLocked = true;
                        // can be persited , it switches back to false immediately

                // Here I'd like to do 2 things
                // 1. change the editor display filter to "only locked segment"
                //    I've been looking in vain in the documentation, any hint ?       

                // 2. trigger a refresh of the editor
                //    Controller.Refresh is inaccessible due to its protection level.
