One of the first questions that arises when the developer in the study of FastReport .NET - how to connect data to the report? Fortunately, this report generator has an intuitive interface designer. However, I'm still saving your time, by talking a little about connecting the source of the data within the report. Looking ahead, I will say that I'm going to show you how to pass the connection string from the user application. So I figuratively divided the article into two parts: connecting to a database within a report and passing the connection string to a report.
