Hello,

Welcome to our Microsoft Q&A platform!

I watched the video you provided and tried it in Visual Studio 2019.

When I opened the Document outline window for the first time, TopAppBar / BottomAppBar was not displayed, so I found it in the Document window after adding it manually, right-clicked, and nothing happened.

I rebuilt the project and restarted Visual Studio and it worked:

You can try restarting Visual Studio, or use related software (Blend for Visual Studio) for programming. But if you are a beginner, you can try to manually enter the relevant xaml tag of the CommandBar, this will help you understand its construction.

Thanks

Did you have to reinstall the Installer for it to work

Not necessary, you can copy this code into the XAML code of the page (Please put it inside the Page tag):

<Page.BottomAppBar> <CommandBar/> </Page.BottomAppBar>

Then you can find BottomAppBar in the Document Outline

Hello, the structure of the entire file looks like this:

<Page ...> <Grid> ... </Grid> <Page.BottomAppBar> <CommandBar /> </Page.BottomAppBar> </Page>

For markup languages, tags must be closed. I see that there doesn't seem to be a closed Page tag in your XAML code

Sorry, I didn't make it clear. The ellipsis refers to the reference content in the Page. These are not written, I just show a structure.

Before you start making your application, you can take a look at this document and learn about the syntax of XAML, which will be helpful for your later study.

Hello, You can type in the XAML code shown in the video. If you are learning how to make a UWP application, you may encounter many problems. If these problems are different, you can open a new thread to ask.

Hi, open a new thread means asking a new question. Regarding the problem you encountered, simply follow the code given in the video and enter it in the XAML interface.

Hello, if you encounter problems during the course of learning, you can post to the forum with detailed instructions so that we can understand your intentions and provide you with solutions.

If you are learning through instructional videos provided by other developers, in addition to asking questions on the platform, you can also directly ask the author of the video.
Learning about UWP application development is not difficult, but it may require you to try more. If you are learning media player, you can also refer to this document.

Videos published earlier may become outdated with version updates, but the documentation is always updated.

Im trying to get the code for app buttons

Soory, but it was this that puzzled me. The code for AppBarButton has been shown in the video, you just need to enter it as written in the video. Many times we don't rely on Toolbox to add controls (of course this is one way), but entering controls in XAML editor will be faster.

I can't select the add command because its grayed out. I can't save my media element I save it successfully before closing the VS after I close then reopen it after saving it disappears after saving it its not there anymore on my document outline after trying to add it from toolbox.

You already have a CommandBar in your BottomAppBar, you can delete it and try again. If you have been unable to add, you can directly enter the CommandBar tag in the XAML editor to create the control.

In addition, you said that MediaElement disappears after Visual Studio is closed. Is it because Visual Studio saves abnormally? Or you can click on the arrow which before the Grid in DocumentOutline, it may be folded.
