A developer asked me recently how to format text in Windows Store apps. Specifically he wanted to add bullet points to some article text he was displaying.
The sample templates like GridApp include a special class called RichTextColumns under the Common folder. This class wraps a normal RichTextBlock (which would run off the screen if its text got too long) to splits it into multiple columns by generating more RichTextBlocks for any overflow. There’s a property on RichTextColumns where you specify the content to be displayed called RichTextContent. It’s where any child markup in Xaml gets stored at runtime. So, in order to format the text, we need to change the content of the RichTextContent property.
