3. How to add Crystal Reports(Standalone) to my VB.NET project?
There are 2 versions of crystal reports available
1. standalone reports like Crystal Reports 10,XI,XI R2
2. Crystal Reports which comes with Visual Studio .Net like
Crystal Reports for Visual Studio-Embedded Reports
if want to add reports, then go to Add Existing Item (right
click on the project name in the solution explorer), browse
to the .rpt file and select it or Add New Item an select
Crystal Reports from the Templates.
if you want to display reports, you should use Crystal
Repors Viewer
coding:
private ReportDocument hierarchicalGroupingReport;
protected void Page_Init(object sender,eventargs e)
{
configurecrystalreports();
}
private void configurecrystalreports()
{
hierarchicalGroupingReport=new ReportDocument();
string reportPath=server.mappath("Hierarchical
Grouping.rpt");
hierarchicalGroupingReport.Load(reportPath);
CrystalReportViewer1.ReportSource=hierarchicalGroupingReport
;
}
There are multiple ways to do that...
1. Using Report bursting indexes.
2. and Sub reports degrade the performance, So avoid using
sub reports
If I am not mistaken then this can be achieved by make
Student report as main report and your other report
familyreport as subreport of the main report opening in new
page.
For different page header of both report what you can do is
in main report dont put any thing in PageHeader or Footer
create a blank group in that create page header for main
report and in group footer create main report page footer
data and on group select option repeat on each page.
May be this will help to solve your problem if I have
understand what you are looking for.
