Why does Grid hide elements?

Question

.NET

I have a page looking like this:

<Page x:Class="Игра.NewGame"

        </Grid>
    </Grid>
</Page>

But in the constructor, Labels in the nested Grid are not displayed -
And when compiling, the stars also disappear -
I started working with C # and WPF just a couple of days ago, so I don’t know what the problem is and how to fix it.

Answer 1

Figured it out myself. It was necessary to set the Padding:"0"Labels and the absolute path to the stars.
