Crystal Reports - Dynamically add parameter link between subreport and main report

Hi everyone, here's my issue:

I have a Crystal Report with a sub report in the page footer that has a parameter field. I know that to pass a parameter to a sub report you have to have a parameter on the main report and link the two parameters.

My problem is that there are a number of different sub reports so they are added to the report at runtime based on the user's selection along with the parameter passed to the main report.

How can I perform a link between the dynamically added subreport's parameter and them main report's parameter. I see that there is a .Links method under the properties of the subreport but I don't know how to use it and what format it's looking for. Here's my code of the addition of the subreport:

VB Code:

If Not IsNull(rsReports("Footer")) Then
       'Page footer
       Set crSection = CReport.Sections.Item("PFa")
       crSection.Suppress = False
       Set crSubReport = crSection.ImportSubreport(strRoot & "\" & rsReports("Footer"), 250, 100)
       With crSubReport
        .OpenSubreport
        .LeftLineStyle = crLSSingleLine
        .RightLineStyle = crLSSingleLine
        .TopLineStyle = crLSSingleLine
        .BottomLineStyle = crLSSingleLine
        .KeepTogether = True
       [COLOR=red].Links.Add.MainReportField ("?FootData")[/COLOR]         
       End With
      End If

Any help or tips would be appreciated. Thanks a lot in advance.

Did you ever find the answer to this? How did you do it with codes?

Sorry for the late reply. I never did find a solution to this or a workaround. I abandoned the subreports and moved on. Sorry.

So what was the equilivalent solution in your other direction?

The parameters in my sub reports would have been nice but they weren’t required so I didn't persue in any further. I still have a sub report, I just don't send any parameters to it.

Thanks, was just wondering.
