SubReports

[MiddleTommy]

I have a report that takes 5 copies of a subreport and feeds it different data in the NeedsDataSource event.
lets call them subreport1 through subreport5
in Q2 this worked fine.
In Q3 subreport1 is displayed where ever the subreports 2 - 5 should be displayed. They have a conditional visibility.

Perhaps using one reference to a subreport multiple times is prohibited in the Q3 release?

Hello MiddleTommy,

We are not sure we understand your inquiry, however multiple SubReport items still can reference the same report in Q3. Generally unexpected behavior may occur if your SubReports Name properties are not serialized and because in Q3 we have introduced report data cashing (to improve the performance for the interactivity features) the name properties are required. Thus our suggestion is to change your Subreports Name property to a custom name - this way you will force the name property serialization.

For further assistance we will highly appreciate if you open a support ticket and send us a sample runnable project that exhibits the issue so we can test it locally.

I uploaded a sample that demonstrates this problem to PITS

Hello ..

I have a similar problem. In my report (master / detail) in the detail section 2 are passing away sub reports with different data sources. Unfortunately, the rendering of the report for both reports the same data source provided. I can resolve the issue through the info in the post before but if I change at any change on the subreport also the name of the report. But when I compile 2 times without changing the name of the report does not call the master of the reports.

Hi Thomas,

We've released an internal build that addresses the problem with the unique names. You can download the fix directly from your account, see the release notes here.

All the best,

I am having the same exact problem. I have a series of labels that I am dynamically populating with data... If i debug, I can tell the data passed as datasource to the subreport instance is different for each instance... Renders the same exact data for every instance... I have installed the latest internal build and it does not solve the problem. Have you found a solution yet? Thanks!

[MiddleTommy]

you have to add a new subreport for each instance of the subreport you have in the report
you can not copy and paste sub reports.
You should see a sub report at the bottom of the designer for each instance of the subreport (even if it is the same subreport used multiple times you should have that same amount of subreports in the bottom of the designer)

That fixed it for me.

Thanks for your reply... i just fixed my issue!

The problem I had was...

 

 

Dim rptLabelSubreport As SubReport = New SubReport

 

rptLabelSubreport.ReportSource =

 

New EHSReporting2011.WM_PickupLabelsChild

 

rptLabelSubreport.Name =

 

"rptLabel" & i & "_WM_PickupLabelsChild"

 

and this fixed it... (I use i as an integer variable to differentiate between the subreport instances)

 

 

Dim rptLabelSubreport As SubReport = New SubReport

 

rptLabelSubreport.ReportSource =

 

New EHSReporting2011.WM_PickupLabelsChild

 

rptLabelSubreport.ReportSource.Name =

 

"rptLabel" & i & "_WM_PickupLabelsChild"

I'm using the Q1 2012 version of Telerik Reporting.  I'm creating a report with 3 subreports in the detail section - the first two subreports are different, but the 3rd is the same class as used in the first.  When I run the report generator I get the "Object should have unique names" error.  I'm adding the subreports via the designer, not programmatically.  I made sure that the name property for each subreport is unique.  In looking at the Component Designer generated code, I can see that it creates new instances of the subreport class for each of the duplicated subreports in the detail section, but it sets the name property of each subreport object to the same literal.  Is there some property I need to set on the subreport items to force unique naming?  I've attached a snippet of the Component Designer generated code - the re-used report class name is "LimitedMeasurementRpt"  and the instance names are "limitedMeasurementRpt1" and "limitedMeasurementRpt2".  Any guidance here would be appreciated.
