Preview Crystal Report on Windows Form in C#

There is a button on a windows form called Print the Report. It should show a report as a new form on the screen if I use the button.

I have created a new form and added crystalviewer but I don’t have any code. I have defined the reportsource.

Which code should I write in click option of the button.

Thanks for your help.

thank you so much your helping,

I wanted to show the report as a form.
I like your opinions so I have finded your web side downloaded the link but it doesn't work.

And also I want to do this;
The report will show on screen and there will be a button on it. It should send to printer the report when I click the button .
