Passing params to Subreport from Main Report - Crystal Reports VS 2005
Hello,
I am having trouble keeping parameter links between the main report and its sub reports.
Background:
I am developing with C# VS 2005, VS 2005 Crystal Reports and SQL Server 2000.
I have several reports (with embedded sub reports) that pass values to different SPROCS in SQL server.
Example:
One Report has three sub reports. The Main report and all three sub reports are linked to different stored procedures but pass the same parameters to their respective SPROC. My C# App passes params to the main report. The main report then passes appropriate params on to each sub report. The main report and sub reports pass appropriate params on to their stored procedures.
This all works great until I Reset the DataSource location to a copy of the same database (Same exact Stored Procedures). After doing this, the link is broken for Parameters between the main report and sub reports. I am unable to re-establish the link. I do this by going to Change Subreport links, choose the main report params and designate the sub report parms, choosing the subreports @ params not PM params.
Does anyone see what might be happening here??
Thanks,
John

No - I actually created the subreports on the fly (On Main Form only) so there is not a subreport to import.

It is probably because the report doesn't really exist.
Do you save the main report at any time?

The links work fine until I change datasource locations (Connect to the same stored procedure in a different dabase).

mlmcc - that was it...
When I first created this report, I was just figuring things out as I went so I didn't create the subreport from an existing report. Rather I created the subreport on the main report. Apparantly this works fine until you point to a different database.
I recreated a report - then imported it into the main report as a subreport and the links work. The question is will they still work when I change datasource locations again?

Thanks mlmcc!
That was exactly the problem. I recreated the subreports as "stand alone" then imported them in as subreports and all params work great.
