[b]To implement functional drill down report follow these steps[/b]

It was like pulling teeth, because I could not find these basic instructions anywhere. I hope this will help in case one experiences the same problem.
 
To implement a functional drill down report on the web follow these steps.

[INDENT]1) create the appropriate functioning report and 
the {[I][COLOR=green]function to populate and return report[/COLOR][/I]}
 
2) place a CrystalReportViewer object on the webform 
(example: [COLOR=blue]CrystalReportViewer1[/COLOR])
 
3) Import at least these namespaces
[COLOR=blue][I]Imports CrystalDecisions.CrystalReports.Engine[/I]
[I]Imports CrystalDecisions.ReportSource[/I]
[I]Imports CrystalDecisions.Web[/I]
[I]Imports CrystalDecisions.Shared[/I][/COLOR]
[COLOR=blue]
[/COLOR]4) Declare a class variable (to hold the report) like:
[COLOR=blue]Dim report As CrystalReport1[/COLOR]
[COLOR=blue]
[/COLOR]5)call the code to populate the report from the [COLOR=red]Page_Init[/COLOR] event handler, like
[COLOR=blue]report =[/COLOR] {[I][COLOR=green]function to populate and return report[/COLOR][/I]}
 
6) bind the report to the viewer control in the [COLOR=red]Page_Load[/COLOR] event handler, like
[COLOR=blue]CrystalReportViewer1.ReportSource = report[/COLOR]

[/INDENT][COLOR=blue]
[/COLOR]That's it. This will help you to get off the ground. Take it from there.
