I can't find any GUI application build with .NET 4.0 Windows Forms Controls and (or) Infragistics. Freeware or somewhat chip. Are there any?

.NET 4.0 would be ideal, but 4.5 or 4.7 are acceptable. Open source is preferred.

You can grab Windows Forms Samples from the Download section under your Infragistics account if you've already signed up or alternatively you can always get a Trial and the installer will also give you the option to install samples.

Those will come as pre-built running apps with a Browser app to navigate and besides component-specific ones, also include showcase samples with multiple controls which seem to match what you're looking for. All samples come with source code projects/solutions you can explore/run and those are still .NET4. You can also have a look around our resources for docs and videos: https://www.infragistics.com/support/windows-forms-help

In any case, if you're absolutely new to this, it seems prudent to familiarize yourself with Windows Forms as a whole and Microsoft's Docs for .NET 4.x are still up. I'd stick to the designer topics as there's a lot you can do visually in Windows Forms :)
