Is there any way to remove wordwrap feature?
I have wpf application in which there is richtextbox control. I added some multiline text with tabs and spaces into this richtextbox.
If I increase the font all my text formatting is change and a vertical scroll bar appears.
I feel this is caused because of word wrap.

Sharda.

Hi,
I have created a sample application.
To reproduce the issue please execute below steps:-
1. Run the application
2. Copy below steps in rich text box.
CodePlex is Microsoft's free open source project hosting site. You can create projects to share with the world, collaborate with others on their projects, and download open source software. Entity Framework is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects.
3. Select the complete text and increase the font by 24. Vertical scroll will appear.
4. Insert tab in front of every line.
5. Click on save.
6. Click on load. You will observe that formatting is changed.
Below is source code.
