How to get Value of another Page in UWP

I dont know how to begin, so i just start with a screenshot and the code of it:

The Textbox.Text-Value should also be in the Textblock at the Bottom here

MainPage.xaml

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="48"/>
    </Grid.RowDefinitions>

    <Frame x:Name="MainContent"/>

    <Grid Grid.Row="1" Background="Gray">
        <TextBlock x:Name="ResultTB"
                   VerticalAlignment="Center"
                   Text="Should also be here"
                   HorizontalAlignment="Center"/>
    </Grid>

</Grid>

MainPage.xaml.cs

public MainPage()
    {
        InitializeComponent();
        MainContent.Navigate(typeof(ContentFrame));
    }

ContentFrame.xaml

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <TextBox x:Name="Input"
             VerticalAlignment="Center"
             HorizontalAlignment="Center"
             Width="200"/>
</Grid>

Now i want to grad ResultTB the text of Input. What is the simplest and best way to do this?

For anyone looking for this in the future - a little similar answer to Alexej but simpler: For Example, lets say I want to change text of object "SomeObject" (x:Name = "SomeObject") which is in MainPage:

MainPage mainFrame = (MainPage)((Frame)Window.Current.Content).Content;
mainFrame.SomeObject = "my text";

You can use override of Navigate method: Frame.Navigate(TypeName, Object)

Where Object is parameter. You can get in another page in OnNavigatedTo event. Something like:

string txt=ResultTB.Text;
MainContent.Navigate(typeof(ContentFrame), txt);

and on another page add OnNavigatedTo event and inside:

var parameter = e.Parameter as string;
