Unwanted border lines appearing when previewing the app

(0) ShareShare
ReportReport
Posted on by 10

On my screen, I have two components. The top banner and then a navigation bar underneath. The first image is the screen when I'm in the editing mode. See how there are no border lines, this is how it is intended to look. The second image is the screen when I enter preview mode. The lines I've circled start to appear and these are unwanted. Does anyone know why this might be? Any help is appreciated, thanks!

    You could try using a gallery as a navigation bar, which not only would reduce the ammount of components needed, but would allow you to expand the navigation panel without needing to add or modify pretty much anything. Should you find this approach interesting you can check out this video by LernenTech.

     

    Additionally, you could just use the modern navigation tab list control, and once again, should you find this approach interesting, you can check out this video by Reza

     

    Hopefully this helps you out, and if you need any further help, feel free to reply again!

    Unfortunately, that did not work. However, in the editing mode now, the lines appear and disappear seemingly at random. The way I currently have the navigation bar setup is simply 6 buttons placed right up against each, so maybe it's an issue with my approach. Do you know of any other way to try and accomplish what I'm trying to do without having the lines appear?

    Greetings!

     

    Just as a hail mary, you could try just setting the BorderStyle of the item, to 

    BorderStyle.None . . . If you are not using the borders for anything of course!
     
    Hopefully this helps you out, and feel free to ask any further thing you may need!
