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 .
Next step is to select the fields from the selected tables ( OrderMaster,
OrderDetails, Product) . Here we are selecting the fields Customername ,
orderdate from ordermastertable , Productname from product table and quantity
from order details table. The field selection screen is look like the following
picture .
After select the fields from tables, click the Finish button because now we are
not using any other functionalities of the Crystal Reports wizard. After that you
will get the Crystal Reports designer window . You can arrange the fields in the
designer window according to your requirement to view the report .
For re-arranging fields in the designer window , you can drag the field object
on the screen . For editing right click the field object and select Edit Text
Object. The following picture shows the sample of designer window after
rearrange the field.
Now the designing part is over and the next step is to call the Crystal Reports in
C# and view it in Crystal Reports Viewer control .
Select the default form (Form1.cs) you created in C# and drag a button and a
CrystalReportViewer control to your form .
After you drag the CrystalReportViewer to your form , it will 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.
When you click the button, the application will ask the username and password.
Later in this tutorial you can find how to avoid asking username and password

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#.
Here we pass a String parameter from C# to Crystal Reports . For example ,
from C# program we pass a customer name as a parameter and show all the
orders of that customer to the Crystal Reports.
In the previous tutorial we saw how to generate a C# - Crystal Reports from
multiple tables. This program is the continuation of previous tutorial , the only
difference is that we pass a Customer Name as String parameter and get the
report of that particular Customer only . Before starting to this section just take
a look at the previous section C# Crystal Reports from multiple tables.
In the previous section we are getting the report of all orders from all customers
, that is , all orders placed by all customers . In this section we pull out the
selected customer report only by passing Customer name as argument.
Hope you understand the previous section well, if not, please click here C#
Crystal Reports from multiple tables.
Next step is to create a String parameter in Crystal report designer window .
Select the Field Explorer from CrystalReport Menu. (Up to here explained in
detail in the previous section C# Crystal Reports from multiple tables)
Then you can see Field Explorer in the Left hand side.
Select Parameter Field from Field Explorer and right Click on Parameter Field.
