how to make SubReports in Crystal Reports SubReport

In this example i am going to describe how to create SubReports in Crystal Reports or Crystal Reports SubReport in ASP.NET.

For this i have used two tables from MS SQL database named Employees and Projects.
Main Crystal Report is fetching data from both the tables and is grouped by Project Name

SubReport is used to display information about respective project and fetching data from Projects Table.

Schema for both the tables in shown below in images, create tables accordingly and add relevant data in it to start.

In next screen select Expand OLEDB(ADO) and Choose create new connection 

 

Select Microsoft OLEDB Provider for SQL server and click next 

 

In next screen check the Integrated security checkbox so that report doesn't ask for username and password  Enter you SQL Server name and Select DataBase from the dropdown ,

 

In next window expand and locate your tables you want to use and add them in right pane 

 

  

In next screen select the fields you want to display in main report and add them in right pane , in my case i am showing fields from two tables in main report 

 Now select the field which you want report to be grouped by ( in this example i m grouping report by Project Name)

Select the report style you want and finish the wizard

Now if you don't want to show SubReport but want to put a hyperlink instead or want to create On-Demand SubReport then do these changes in the design of report 

Right click on SubReport in Design View and select Format Object 

 

In the window opened ,Go to SubReport tab, Change the SubReport name to text you want to show as hyperlink, Check the On-demand SubReport check box and click on ok

On default.aspx page drag CrystalReportViewer from toolbox and assign CrystalReport we just created as source
Html source will go like this (AutoGenerated)

<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" 
                        AutoDataBind="True" Height="1039px" 
                        ReportSourceID="CrystalReportSource1" 
                        Width="901px" />
<CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
<Report FileName="CrystalReport.rpt">
</Report>
</CR:CrystalReportSource>
