文字换行不适用于WPF RichtextBox

Question

I have a WPF User Control with a RichTextBox in it. I am consuming this User Control in one the WPF pages. Alongwith it, I am using a FlowDocumentPageViewer with a ListView in it. Later on, I am assigning the data of ListView in the RichTextBox using a FlowDocument. Everything goes well but the wrap functionality does not work in it.

Answer 2

To diagnose the problem for wrap functionality, I segregated the components being used in the current XAML code into different solutions.

Please refer the following description to understand the steps followed in the analysis:-

• A solution with List View having DataGrid (with two columns and multiple rows):- The wrap functionality was working in this solution.
• A solution with FlowDocumentPageViewer having FlowDocument with the ListView used in the above solution:- The wrap functionality was working in this solution.
• A solution with the User Control(referred from MultiLinha) and above FlowDocumentPageViewer. The wrap functionality was not working in this solution.

After isolating the components in this way, I observed that while integrating the User Control with FlowDocumentPageViewer the wrap functionality stopped working.

This was resolved when I put Style with property Text Wrapping set to Wrap for the FlowDocument itself.
