Is it possible for WPF pages to share XAML snippets?

Question

Hi Microsoft Geniuses,

The attached 8 files indicate the specific scenario for my question. Please remove the ".txt" extension at the end of each file name and add "." before the left extensions.

Thanks

Hi Jenny,
to solve your problem you can use Binding instead of assign in CodeBehind.

• in page use ContentControl bound to property in DataContext <Grid x:Name="grd" HorizontalAlignment="Center">
  <!-- common XAML to be shared -->
  <ContentControl Content="{Binding LoadedXaml}"/>
  <!-- end common XAML to be shared -->
  <TextBlock FontSize="24" TextWrapping="Wrap"
  Text="HTML" HorizontalAlignment="Center" Margin="114,80,114,140"/>
  <TextBlock HorizontalAlignment="Left" Margin="60,115,0,0" Visibility="{Binding TbExplainVisibility}"
  TextWrapping="Wrap" Text="HTML is..." VerticalAlignment="Top" Height="26" Width="148"/>
  </Grid>
• for complex XAML use UserControl (in file) with Command-Binding and Interactivity.dll:

• and in CodeBehind include properties for Binding and use CodeBehind as DataContext:

The code in my XamlWithControls.xaml is :

1.If you want to get the Button's content[Button from XamlWithControls], you can add a ContentControl in the Page.xaml and bind the data like below:

        <ContentControl Content="{Binding LoadedXaml}"></ContentControl>  

2.If you want get the all xaml code as the picture shown, add the below code:

 public string LoadedXamlCode  
        {  
            get => XamlWriter.Save((XamlReader.Load(new FileStream("XamlWithControls.xaml", FileMode.Open))));  
        }  

Then bind the data to the ContentControl like:

 <ContentControl Content="{Binding LoadedXamlCode}"></ContentControl>  

3.If you want to show the Button in the Page1, you can name your gird as MyGrid and add the below code in the cs:
