The rest (that has been reomved) is just code that does more text-coloring. This is the code-behind C#, lengthy, but it has been trimmed down to only enough to show what's going on. I'm fairly new to WPF and there's much to it that is still mysterious to me, so the solution may be obvious to someone with more experience with it. "formattedText.MaxTextWidth = this.ViewportWidth // space for scrollbar" I've tracked the problem to a line in OnRender: The scrollbar is visible and it changes the size of the drag button to show that it sees that the unwrapped text is wider than the viewing area, but since the text has already been wrapped, dragging it doesn't make any difference. I've tried adding a horizontal scrollbar but that doesn't help. In a normal TextBox, simply setting the TextWrapping property to NoWrap does the trick, but not with CodeBox (which inherits from TextBox in code-behind). I've used the CodeBox project from CodeProject and it works very well except for the fact that I can't disable text wrapping.
