[UWP][C#] Adding text to RichTextBlock

First of all I am completely new into both XAML and C#, so please forgive me for some stupid errors. An explanation is much more appreciated.

I've been struggling this last hours trying to figure out one of the simplest things: how to add text to a RichTextBlock when a button is pressed. I've tried some solutions that I found on Internet but none of them actually worked.

In particular it seems like there aren't the necessary references. For instance VS does not recognize the following code : Run myrun = new Run(); nor Paragraph mypar = new Paragraph(); or myrichtextblock.document.

What am I missing?

Solution

  • Check this example:

    Taken from MSDN documentation

    https://msdn.microsoft.com/library/windows/apps/br227565

    // Create a RichTextBlock, a Paragraph and a Run.
RichTextBlock richTextBlock = new RichTextBlock();
Paragraph paragraph = new Paragraph();
Run run = new Run();

// Customize some properties on the RichTextBlock.
richTextBlock.IsTextSelectionEnabled = true;
richTextBlock.TextWrapping = TextWrapping.Wrap;
run.Text = "This is some sample text to show the wrapping behavior.";
richTextBlock.Width = 200;

// Add the Run to the Paragraph, the Paragraph to the RichTextBlock.
paragraph.Inlines.Add(run);
richTextBlock.Blocks.Add(paragraph);

// Add the RichTextBlock to the visual tree (assumes stackPanel is decalred in XAML).
stackPanel.Children.Add(richTextBlock);

    Just see how to add text in this example and modify the code to put inside of your click event of your button
