The issue is difficult to explain and reproduce. I've seen this happen a few times before but can't exactly nail down the cause except to say that whenever you start moving the control around, i.e., setting the Align to different values, saving it, reopening to do more work, saving, moving the control on the form, left side, right side, client, resizing it for Windows, resizing it for Android, compiling it for different Android tablets (LG Pad 7" kitkat 4.4.2 800x1200, Acer Iconia Tab 8 kitkat 4.4.4 800x1200, and Dell Venue 8 1200x1900 kitkat 4.4.4) and the list goes on with respect to doing various work on the project.
My only way to resolve it was to rebuild the whole project from scratch and thats not something I want to keep doing for every project I'm working on. But in the project I am working on, I am too deep in the design, changes and upgrades, to rebuild from scratch all over again. And, the problem with rebuilding the navbar is having to do with the listviews, since they are each connected to a livebinding query. Even removing and rebuilding a panel in the navbar requires me to rebuild the listview and query and livebinding connections. Its a lot of work to have to do everything navbar panels decide to scramble their placement order. Otherwise, I don't know whatever to do except to rebuild the project all over again. The navbar is the center point of the application, for both windows and android. And without the navbar, there is no tool or else I would have to build it without the navbar and have all the listviews showing in the apps window, (very messy). Its much more tidier and elegant looking to use the navbar.
