All C# Crystal Reports Tutorial in this website is based on the following database - crystaldb. So before you begin this section , please take a look at the database structure of crystaldb - Click Here C# crystaldb

Here we are going to generate Crystal Reports from multiple tables in C#. Here we have three tables (ordermaster , orderdetails and product ) and we are generating a Crystal Report from these three tables by connecting each table with their related fields.

If you are new to Crystal Reports and do not know how to create Crystal Reports from C# , please take a look at the section step by step tutorial for creating a Crystal Reports from C#.

Hope you understand the basics of generating a Crystal Reports in C# , this section is the continuation of the first part, so here we avoid some basic steps and start from the table selection of Crystal Reports.

Select all table from the table list to right side list box, because we are creating report from three tables ( OrderMaster, OrderDetails, Product) . If you don't know up to this part of the tutorial , refer previous tutorial for up to selecting databese for Crystal reports.

The next step is to make relations between these selected tables. Here we are connecting the related fields from each table. For that we arrange the tables in visible area in the list (this is not necessary ) and select the fields that we want to make relation and drag to the related field of the other selected tables. After made the relations with tables the screen is look like the following picture .

You have to include CrystalDecisions.CrystalReports.Engine in your C# Source Code.

using CrystalDecisions.CrystalReports.Engine;

Copy and paste the following source code and run your C# project




using System;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            ReportDocument cryRpt = new ReportDocument();
            cryRpt.Load(PUT CRYSTAL REPORT PATH HERE\\CrystalReport1.rpt");
            crystalReportViewer1.ReportSource = cryRpt;
            crystalReportViewer1.Refresh();
        }
    }
}

NOTES:
cryRpt.Load(PUT CRYSTAL REPORT PATH HERE\\CrystalReport1.rpt");

The Crystal Reports file path in your C# project files location, there you can see CrystalReport1.rpt . So give the full path name of Crystal Reports file like c:\projects\crystalreports\CrystalReport1.rpt

After you run the source code you will get the report like this.
