What are the functions of the crystal report through the code?

1, I use the crystal report only through the enhanced report class and srystulReportviewer control of the data display, and the drawing of the table. I would like to ask, what kind of functions can Crystal Reports achieve? I hope you can summarize them. Thank you
2. I found that when a crystal report file CRTest is created, the design window and code window of CRTest1.cs and CRTest1.resx seem to be tables. What's the use in it? Can you add some code in CRTest1.cs code designer to achieve some functions?
3. By the way, how to realize print preview, method and source code can be used, thank you.

I mainly targeted the window program above, and I didn't find the print preview function on the Internet.
