Control DiffViewer: doesn't show text but color only

[cpallotti73]

I'm probably wrong, but the control displays the different colors in the differences lines but without text (see you image attached).
Same problem if set 'ShowInline'.
What am I doing wrong?

I use VS2019 + .net framework 4.6.1

Thanks in advance

@kingcean Can you take a look?

Hi @cpallotti73 could you please try to set Foreground property by a color or any kind of Brush to have a test?

Since I haven't heard back from @cpallotti73 , closing for now

I get this behaviour as well - no matter what I do. To begin with, I thought it was due to my high-DPI monitor but it can be consistently reproduced on all the dev machines that I have. Presumably the "ElementHost" is playing up??

Hi @Scandal-UK could you please try to set Foreground property by a color to have a test? And does this happen in WinForms or WPF application?

[Scandal-UK]

I have tried that - and even setting the font. This is WinForms (which I think just uses an ElementHost? I haven't looked closely), targeting .NET 5 or .NET Core 3.1.

Could you please confirm if you are running the project DiffPlex.WindowsForms.Demo? It is demo of WinForms application.

Of course not, I followed the instructions on the front page?? I have created my own control now with two RichTextBox instances in a SplitContainer (with synchronised scrolling), but I'd rather use your control.

Steps to reproduce:

• Create new WinForms project (targeting .NET 5 or .NET Core 3.1)
• Add NuGet package: DiffPlex.Wpf
• Drop DiffViewer from toolbox onto form (optionally set Dock to Fill)
• Add OldText and NewText values in code-behind (either in constructor or Load event)
• Run the solution

Could you please run the demo DiffPlex.WindowsForms.Demo mentioned above to have a test? Or run net5.0-windows\DiffPlex.WindowsForms.Demo.exe in DiffPlex.Win32.Demo.zip which I built locally.

• If it works well, could you please compare the code between yours and the one in demo and let me know if I can provide any help?
• If not, could you please share details information about your environment (like OS version, language and DPI scale) to me so that I can try to repro?
