I couldn't find a full example of this, I had to put bits and pieces together before I got this working.
Let's say you have a datasource, and in that datasource, one of the datamembers is a string that contains some FlowDocument XAML. For example:
<Section xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<Paragraph>This is a test.</Paragraph>
</Section>
Unfortunately, there's no way to directly bind a string to a FlowDocument object. However, XAML databinding allows the use of custom converters that allows you to take that string and convert it to whatever you like. To do this, create a class:
Namespace Converters
<ValueConversion(GetType(Object), GetType(FlowDocument))> Public Class FlowDocumentConverter
Implements IValueConverter
Public Function Convert(ByVal objValue As Object, ByVal tTarget As Type, ByVal objParam As Object, _
ByVal ciCulture As CultureInfo) As Object Implements IValueConverter.Convert
Using msDocument As New MemoryStream((New ASCIIEncoding).GetBytes(CStr(objValue)))
Dim fdDocument As New FlowDocument()
Dim trDocument As New TextRange(fdDocument.ContentStart, fdDocument.ContentEnd)
trDocument.Load(msDocument, DataFormats.Xaml)
trDocument = Nothing
Return fdDocument
End Using
End Function
Public Function ConvertBack(ByVal objValue As Object, ByVal tTarget As Type, ByVal objParam As Object, _
ByVal ciCulture As CultureInfo) As Object Implements IValueConverter.ConvertBack
Return Nothing 'Not interested in converting back from a FlowDocument to a String
End Function
End Class
End Namespace
Now add your xmlns to the page/usercontrol/window/whatever...
Just replace "PropertyName" with the name of the property or column that has the XAML FlowDocument string you wish to use.
It's a little counter-intuitive, it would be nice if you could just Document="{Binding PropertyName}" and be done with it, converting it to a FlowDocument on the fly... but the solution here is easy enough.
This is my blog where I give my thoughts and opinions on various topics and share my creative endeavors with the world. I run two personal blogs, but combine them here for ease of access.
Blogger - My oldest blog using the Blogger platform contains posts full of opinions, gaming, and code.
Tumblr - Tumblr posts are all about my creative side, containing music, videos, writings, and updates on my web creations.

In California, truck license plates are 7 characters, all numbers except for one letter in either the second or the sixth position. Whenever that letter is an X, I get nerd snipped into treating it as a multiplication problem and solving it in my head.
we should have paid more attention to the cats who, for decades, put their bodies on the line to walk on keyboards and sit on laptops and prevent us from programming
Former 2 time world champion DogPlayingTetris becomes the first player to ever rollover the level counter in NES Tetris, performing what's known in the community as "Rebirth". Final score: 29,486,164, 4216 lines, level 347 (256 + 91)... all huge world records. #tetris
I'd also love a 6 hour layover overnight instead of taking the red eye I was going to take and be 7 hours later getting into Cleveland than I wanted, why do you ask? #airporthell
Why yes, I'd love to leave at 4:40 to get to the airport at 6:20 for an 8:20 flight that got delayed to 9:05 which is too late for my connection so now I'm on a 10:20 flight instead. Why do you ask? #airporthell
@shanselman Who at Microsoft do I have to bribe to fix ADO so that those of us on dark mode who copy/paste text from one task to another can do so without our friends on light mode seeing dark text on a dark background?
I updated the blog post with a statement from Revival. While I'm not particularly happy with Revival's decision, I understand their motives. It's just a shame that it was someone from Interplay that had to go and do this. "By games for gamers" my ass.
Damn, got another Tetris world record! This time in the arcade variant developed by Atari. 6,008,005 points, 5,386 lines, round 363. Be warned, it's nearly FIVE HOURS. https://www.twitch.tv/videos/2131759212
