Common Interface for different Reports

[JCruz063]

Hi Guys,
I'm developing a web site that allows clients to print from a variety of reports. I may have about 15 different reports, and based on what the client selects, only one of them is displayed.

As you know, when you create a Report, the Crystal Reports engine creates a class for such report. At run time, what I do is I (1)instantiate objects of the appropriate report type (based on what the user selects), (2) set a couple of its properties based on what the client has selected, and (3) assign the object to the ReportViewer so that clients can view the report. Since I have 15 different reports, the code I have to write is very lengthy and inefficient.

[COLOR=green]// Create a varible for each report[/color]
ReportType1 rpt1;
ReportType2 rpt2;
ReportType3 rpt3;
[COLOR=green]// ... 
// All the way to 15 or more

// Now see which report the user wants[/color]
if (selectedRprt == 1)
   rpt1 = [COLOR=blue]new[/color] ReportType1();
[COLOR=green]   // Do other stuff[/color]
else if (selectedRprt == 2)
   rpt2 = [COLOR=blue]new[/color] ReportType2();
[COLOR=green]   // Do other stuff[/color]
else if [COLOR=green]// and on and on and on...[/color]

It's a nightmare!!! I know I could use a switch statement instead of all the if's above but that's not the issue. I was hoping to see if I could create an interface which all my reports could implement so that the above code could be reduced. Can anybody tell me how to do this?

Thanks!
