VB.NET Crystal Reports from multiple tables
All Crystal Reports programming samples in this tutorials is based on the following database (crystaldb) . Please take a look at the database structure before you start this tutorial - Click here to see Database Structure .
Here we are going to do is to generate Crystal Reports from multiple tables. Here we have three table (ordermaster , orderdetails amd product ) and we are generating report from these three tables by connecting each tables with their related fields.
Open Visual Studio .NET and select a new Visual Basic .NET Project.
From main menu in Visual Studio select PROJECT-->Add New Item . Then Add New Item dialogue will appear and select Crystal Reports from the dialogue box.
Select Report type from Crystal Reports gallery.
Accept the default settings and click OK.
Next step is to select the appropriate connection to your database. Here we are going to select OLEDB connection for SQL Server
Select OLE DB (ADO) from Create New Connection.
Select Microsoft OLE DB Provider for SQL Server .
Next screen is the SQL Server authentication screen . Select your Sql Server name , enter userid , password and select your Database Name . Click next , Then the screen shows OLE DB Property values , leave it as it is , and click finish.
Then you will get your Server name under OLEDB Connection from there select database name (Crystaldb) and click the tables , then you can see all your tables from your database.
Select all table from the table list to right side list box, because we are creating report from three tables ( OrderMaster, OrderDetails, Product) .
The next step is to make relation 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 field we are going to make relation and drag to the related field of the other table. After made the relation the screen is look like the following picture.
Next step is to select the fields from the tables . Here we are selecting only Customername , orderdate from ordermastertable , Productname from product table and quantity from order details.
Click the Finish button because now we are not using other functionalities of this 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 rearranging you can drag the field object in 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 created Crystal Reports in VB.NET through Crystal Reports Viewer control .
Select the default form (Form1.vb) you created in VB.NET and drag a button and CrystalReportViewer control to your form.
Select Form's source code view and put the code on top.
Put the following source code in the button click event
cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt")
The Crystal Report is in your project location, there you can see CrystalReport1.rpt . So give the full path name of report here.
After you run the source code you will get the report like this.
Here we connected three tables related field and get the result . If you have any comments please contact the email address in our contact page.
